At the time when William Herschel brought his sister back with him to Bath, he had established himself there as a teacher of music, numbering among his pupils many ladies of rank. He was also organist of the Octagon Chapel, and frequently composed anthems, chants, and whole services for the choir under his management. On the retirement of Mr. Linley (father of the celebrated singer, afterwards the beautiful Mrs. Sheridan) from the direction of the Public Concerts, he at once added this to his other avocations, and was consequently immersed in business of the most laborious and harassing kind during the whole of the Bath season. But he considered all this professional work only as the means to an end; devotion to music produced income and a certain degree of leisure, and these were becoming every day more imperatively necessary. Every spare moment of the day, and many hours stolen from the night, had long been devoted to the studies which were compelling him to become himself an observer of the heavens. Insufficient mechanical means roused his inventive genius; and, as all the world knows, the mirror for the mighty forty-foot telescope was the crowning result. To his pupils he was known as not a music-master alone. Some ladies had lessons in astronomy from him, and, at the invitation of his friend Dr. Watson, he became a member of a philosophical society then recently started in Bath, to which he for several years contributed a great number of papers on various scientific subjects. It soon came to pass that the gentlemen who sought interviews with him, asking for a peep through the wonderful tube, carried stories of what they had seen to London, and these were not long in finding their way to St. James’s.

It was thus at the very turning-point of her brother’s career that Caroline Herschel became his companion and fellow-worker. No contrast could be sharper than that presented by the narrow domestic routine she had left to the life of ceaseless and inexhaustible activity into which she was plunged;—unless, indeed, it be that presented by the nature of the events she has to record, and the tone in which they are recorded. For ten years she persevered at Bath, singing when she was told to sing, copying when she was told to copy, “lending a hand” in the workshop, and taking her full share in all the stirring and exciting changes by which the musician became the King’s astronomer and a celebrity; but she never, by a single word, betrays how these wonderful events affected her; nor ever indulges in the slightest approach to an original sentiment, comment, or reflection not strictly connected with the present fact. Whether it be to record the presentation of the “golden medal,” or the dishonesty of the incorrigible Betties who then, and till her life’s end, so sorely tried her peace of mind, there is no difference in the style or spirit of the “Recollections.” Partly as apology and partly as complaint, the one grievance is harped on, even when fifty years’ experience might have convinced her that she had done something more for herself and the world than earn her bread by her own labour. “In short,” she writes, “I have been throughout annoyed and hindered in my endeavours at perfecting myself in any branch of knowledge by which I could hope to gain a creditable livelihood.” It is seldom, however, that she is diverted from the main theme to write about herself otherwise than incidentally, and in a note addressed to her nephew, she says:—“My only reason for saying so much of myself is to show with what miserable assistance your father made shift to obtaining the means of exploring the heavens.”

“On the afternoon of August 28th, 1772, I arrived with my brother at his house No. 7, New King Street, Bath, where we were received only by Mr. Bulman’s family, who occupied the parlour floor, and had the management of his servant and household affairs. My brother had formerly boarded with them at Leeds, whence, on Mr. Bulman’s failure in business, they had removed to Bath, where my brother procured for him the place of Clerk at the Octagon Chapel.... On our journey he had taken every opportunity to make me hope to find in Mrs. Bulman a well-informed and well-meaning friend, and in her daughter, a few years younger than myself, an agreeable companion. But as I knew no more English than the few words which I had on our journey learned to repeat like a parrot, it may be easily supposed that it would require some time before I could feel comfortable among strangers. But as the season for the arrival of visitors to the Baths does not begin till October, my brother had leisure to try my capacity for becoming a useful singer for his concerts and oratorios, and being very well satisfied with my voice, I had two or three lessons every day, and the hours which were not spent at the harpsichord were employed in putting me in the way of managing the family.... On the second morning, on meeting my brother at breakfast, he began immediately to give me a lesson in English and arithmetic, and showed me the way of booking and keeping accounts of cash received and laid out.... By way of relaxation we talked of astronomy and the bright constellations with which I had made acquaintance during the fine nights we spent on the Postwagen travelling through Holland.

“My brother Alexander, who had been some time in England, boarded and lodged with his elder brother, and with myself, occupied the attic. The first floor, which was furnished in the newest and most handsome style, my brother kept for himself. The front room containing the harpsichord was always in order to receive his musical friends and scholars at little private concerts or rehearsals.... Sundays I received a sum for the weekly expenses, of which my housekeeping book (written in English) showed the amount laid out, and my purse the remaining cash. One of the principal things required was to market, and about six weeks after coming to England I was sent alone among fishwomen, butchers, basket-women, &c., and I brought home whatever in my fright I could pick up.... My brother Alex, who was now returned from his summer engagement, used to watch me at a distance, unknown to me, till he saw me safe on my way home. But all attempts to introduce any order in our little household proved vain, owing to the servant my brother then had—a hot-headed old Welshwoman. All the articles, tea-things, &c., which I was to take in charge, were almost all destroyed: knives eaten up by rust, heaters of the tea-urn found in the ash-hole, &c. And what still further increased my difficulty was, that my brother’s time was entirely taken up with business, so that I only saw him at meals. Breakfast was at 7 o’clock or before (much too early for me, who would rather have remained up all night than be obliged to rise at so early an hour)....

“The three winter months passed on very heavily. I had to struggle against heimweh (home sickness) and low spirits, and to answer my sister’s melancholy letters on the death of her husband, by which she became a widow with six children. I knew too little English to derive any consolation from the society of those who were about me, so that, dinner-time excepted, I was entirely left to myself.”

Introductions to her brother’s scholars led to occasional evening parties, where her voice was in demand as well for single songs as to take part in duets and glees, and one of these ladies, Mrs. Colebrook, invited her to go to London on a visit. This visit was prolonged for several weeks owing to the deep snow, which rendered the roads impassable. The Duchess of Ancaster is said to have offered any sum to have a passage cut near Devizes, but without success, her Grace was in consequence unable to be present on the 18th January, when the Queen’s birthday was kept. Operas, plays, auctions, and all the usual amusements of the town, gave Miss Herschel a glimpse of the gay world; but the expense of dress and chairmen troubled her spirit too much to allow of her finding pleasure in these dissipations; and although Mrs. Colebrook is allowed to be both “learned and clever,” her society does not appear to have contributed much more to her happiness than that of some younger ladies whose companionship was offered, but whose visits she did not encourage, because, as she bluntly explains, she “thought them very little better than idiots.”

“The time when I could hope to receive a little more of my brother’s instruction and attention was now drawing near; for after Easter, Bath becomes very empty; only a few of his scholars whose families were resident in the neighbourhood remaining. But, I was greatly disappointed; for, in consequence of the harassing and fatiguing life he had led during the winter months, he used to retire to bed with a bason of milk or glass of water, and Smith’s ‘Harmonics and Optics,’ Ferguson’s ‘Astronomy,’ &c., and so went to sleep buried under his favourite authors; and his first thoughts on rising were how to obtain instruments for viewing those objects himself of which he had been reading. There being in one of the shops a two and a half foot Gregorian telescope to be let, it was for some time taken in requisition, and served not only for viewing the heavens but for making experiments on its construction.... It soon appeared that my brother was not contented with knowing what former observers had seen, for he began to contrive a telescope eighteen or twenty feet long (I believe after Huyghens’ description).... I was much hindered in my musical practice by my help being continually wanted in the execution of the various contrivances, and I had to amuse myself with making the tube of pasteboard for the glasses which were to arrive from London, for at that time no optician had settled at Bath. But when all was finished, no one besides my brother could get a glimpse of Jupiter or Saturn, for the great length of the tube would not allow it to be kept in a straight line. This difficulty, however, was soon removed by substituting tin tubes.... My brother wrote to inquire the price of a reflecting mirror for (I believe) a five or six foot telescope. The answer was, there were none of so large a size, but a person offered to make one at a price much above what my brother thought proper to give.... About this time he bought of a Quaker resident at Bath, who had formerly made attempts at polishing mirrors, all his rubbish of patterns, tools, hones, polishers, unfinished mirrors, &c., but all for small Gregorians, and none above two or three inches diameter.

“But nothing serious could be attempted, for want of time, till the beginning of June, when some of my brother’s scholars were leaving Bath; and then to my sorrow I saw almost every room turned into a workshop. A cabinet-maker making a tube and stands of all descriptions in a handsomely furnished drawing-room; Alex putting up a huge turning machine (which he had brought in the autumn from Bristol, where he used to spend the summer) in a bedroom, for turning patterns, grinding glasses, and turning eye-pieces, &c. At the same time music durst not lie entirely dormant during the summer, and my brother had frequent rehearsals at home, where Miss Farinelli, an Italian singer, was met by several of the principal performers he had engaged for the winter concerts.... He composed glees, catches, &c., for such voices as he could secure, as it was not easy to find a singer to take the place of Miss Linley.... Sometimes, in the absence of Fisher, he gave a concerto on the oboe, or a sonata on the harpsichord; and the solos on the violoncello of my brother Alexander were divine!... He also took great delight in a choir of singers who performed the cathedral service at the Octagon Chapel, for whom he composed many excellent anthems, chants, and psalm tunes.^[5] As soon as I could pronounce English well enough I was obliged to attend the rehearsals, and on Sundays at morning and evening service, which, though I did not much like at first, I soon found to be both pleasant and useful.

“But every leisure moment was eagerly snatched at for resuming some work which was in progress, without taking time for changing dress, and many a lace ruffle was torn or bespattered by molten pitch, &c., besides the danger to which he continually exposed himself by the uncommon precipitancy which accompanied all his actions, of which we had a melancholy sample one Saturday evening, when both brothers returned from a concert between 11 and 12 o’clock, my eldest brother pleasing himself all the way home with being at liberty to spend the next day (except a few hours’ attendance at chapel) at the turning bench, but recollecting that the tools wanted sharpening, they ran with the lantern and tools to our landlord’s grindstone in a public yard, where they did not wish to be seen on a Sunday morning.... But my brother William was soon brought back fainting by Alex with the loss of one of his finger-nails. This happened in the winter of 1775, at a house situated near Walcot turnpike, to which my brother had moved at midsummer, 1774. On a grass plot behind the house preparation was immediately made for erecting a twenty-foot telescope, for which, among seven and ten foot mirrors then in hand, one of twelve foot was preparing; this house offered more room for workshops, and a place on the roof for observing.

“During this summer I lost the only female acquaintances (not friends) I ever had an opportunity of being very intimate with by Bulmer’s family returning again to Leeds. For my time was so much taken up with copying music and practising, besides attendance on my brother when polishing, since by way of keeping him alive I was constantly obliged to feed him by putting the victuals by bits into his mouth. This was once the case when, in order to finish a seven foot mirror, he had not taken his hands from it for sixteen hours together.^[6] In general he was never unemployed at meals, but was always at those times contriving or making drawings of whatever came in his mind. Generally I was obliged to read to him whilst he was at the turning lathe, or polishing mirrors, Don Quixote, Arabian Nights’ Entertainment, the novels of Sterne, Fielding, &c.; serving tea and supper without interrupting the work with which he was engaged, ... and sometimes lending a hand. I became in time as useful a member of the workshop as a boy might be to his master in the first year of his apprenticeship.... But as I was to take a part the next year in the oratorios, I had for a whole twelvemonth two lessons per week from Miss Fleming, the celebrated dancing mistress, to drill me for a gentlewoman (God knows how she succeeded). So we lived on without interruption. My brother Alex was absent from Bath for some months every summer, but when at home he took much pleasure to execute some turning or clockmaker’s work for his brother.”

News from Hanover put a sudden stop for a time to all these labours. The mother wrote, in the utmost distress, to say that Dietrich had disappeared from his home, it was supposed with the intention of going to India “with a young idler not older than himself.” His brother immediately left the lathe at which he was turning an eye-piece in cocoanut, and started for Holland, whence he proceeded to Hanover, failing to meet his brother as he expected. Meanwhile the sister received a letter to say that Dietrich was laid up very ill at an inn in Wapping. Alexander posted to town, removed him to a lodging, and after a fortnight’s nursing, brought him to Bath, where, on his brother William’s return, he found him being well cared for by his sister, who kept him to a diet of “roasted apples and barley-water.” Dietrich remained in England, his brother easily procuring him employment until 1779, when he returned to Hanover, and shortly afterwards married a Miss Reif. The family now moved to a larger house, 19, New King Street, which had a garden behind it, and open space down to the river. It is incidentally mentioned, “that here many interesting discoveries besides the Georgium Sidus were made.”

In preparation for the oratorios to be performed during Lent, Miss Herschel mentions that she copied the scores of the “Messiah” and “Judas Maccabæus” into parts for an orchestra of nearly one hundred performers, and the vocal parts of “Samson,” besides instructing the treble singers, of which she was now herself the first. On the occasion of her first public appearance, her brother presented her with ten guineas for her dress,—

“And that my choice could not have been a bad one I conclude from having been pronounced by Mr. Palmer (the then proprietor of the Bath theatre) to be an ornament to the stage. And as to acquitting myself in giving my songs and recitatives in the ‘Messiah,’ ‘Judas Maccabæus,’ &c., I had the satisfaction of being complimented by my friends, the Marchioness of Lothian, &c., who were present at the rehearsals, for pronouncing my words like an Englishwoman.”

It is evident that had she chosen to persevere, her reputation as a singer would have been secure. The following year she was first singer at the concerts, and was offered an engagement for the Birmingham Festival, which she declined, having resolved only to sing in public where her brother was conductor. At this time he had repeated proposals from London publishers to bring out some of his vocal compositions, but with the exception of “The Echo” catch, none of them ever appeared in print. Besides the regular Sunday services, concerts and oratorios had to be prepared for and performed in steady routine, sometimes at Bristol also, while the poor prima-donna-housekeeper “hobbled on” with one dishonest servant after another, until Whit Sunday, 1782, when both brother and sister played and sung for the last time, in St. Margaret’s Chapel. On this occasion, their last performance in public, the anthem selected for the day was one of the last compositions, of which mention has been made above.

The name of William Herschel was fast becoming famous, as a writer, a discoverer, and the possessor and inventor of instruments of unheard-of power. He was now about to be released from the necessity of devoting the time to music which he was eager to give to astronomical science.^[7] It came about as follows:—

... “He was now frequently interrupted by visitors who were introduced by some of his resident scholars, among whom I remember Sir Harry Engelfield, Dr. Blagden, and Dr. Maskelyne. With the latter he was engaged in a long conversation, which to me sounded like quarrelling, and the first words my brother said after he was gone was: ‘That is a devil of a fellow.’... I suppose their names were not known, or were forgotten; for it was not till the year 1782 or 1783 that a memorandum of the names of visitors was thought of.... My brother applied himself to perfect his mirrors, erecting in his garden a stand for his twenty-foot telescope; many trials were necessary before the required motions for such an unwieldy machine could be contrived. Many attempts were made by way of experiment against a mirror for an intended thirty-foot telescope could be completed, for which, between whiles (not interrupting the observations with seven, ten, and twenty-foot, and writing papers for both the Royal and Bath Philosophical Societies) gauges, shapes, weight, &c., of the mirror were calculated, and trials of the composition of the metal were made. In short, I saw nothing else and heard nothing else talked of but about these things when my brothers were together. Alex was always very alert, assisting when anything new was going forward, but he wanted perseverance, and never liked to confine himself at home for many hours together. And so it happened that my brother William was obliged to make trial of my abilities in copying for him catalogues, tables, &c., and sometimes whole papers which were lent him for his perusal. Among them was one by Mr. Michel and a catalogue of Christian Mayer in Latin, which kept me employed when my brother was at the telescope at night. When I found that a hand was sometimes wanted when any particular measures were to be made with the lamp micrometer, &c., or a fire to be kept up, or a dish of coffee necessary during a long night’s watching, I undertook with pleasure what others might have thought a hardship.... Since the discovery of the Georgium Sidus [March 13, 1781], I believe few men of learning or consequence left Bath before they had seen and conversed with its discoverer, and thought themselves fortunate in finding him at home on their repeated visits. Sir William Watson^[8] was almost an intimate, for hardly a day passed but he had something to communicate from the letters which he received from Sir Joseph Banks and other members of the Royal Society, from which it appeared that my brother was expected in town to receive the gold medal. The end of November was the most precarious season for absenting himself. But Sir William went with him, and it was arranged so that they set out with the diligence at night, and by that means his absence did not last above three or four days, when my brother returned alone, Sir William remaining with his father.

“Now a very busy winter was commencing; for my brother had engaged himself to conduct the oratorios conjointly with Ronzini, and had made himself answerable for the payment of the engaged performers, for his credit ever stood high in the opinion of every one he had to deal with. (He lost considerably by this arrangement.) But, though at times much harassed with business, the mirror for the thirty-foot reflector was never out of his mind, and if a minute could but be spared in going from one scholar to another, or giving one the slip, he called at home to see how the men went on with the furnace, which was built in a room below, even with the garden.

“The mirror was to be cast in a mould of loam prepared from horse dung, of which an immense quantity was to be pounded in a mortar and sifted through a fine sieve. It was an endless piece of work, and served me for many an hour’s exercise; and Alex frequently took his turn at it, for we were all eager to do something towards the great undertaking. Even Sir William Watson would sometimes take the pestle from me when he found me in the work-room, where he expected to find his friend, in whose concerns he took so much interest that he felt much disappointed at not being allowed to pay for the metal. But I do not think my brother ever accepted pecuniary assistance from any one of his friends, and on this occasion he declined the offer by saying it was paid for already.

“Among the Bath visitors were many philosophical gentlemen who used to frequent the levées at St. James’s, when in town. Colonel Walsh, in particular, informed my brother that from a conversation he had had with His Majesty, it appeared that in the spring he was to come with his seven-foot telescope to the King. Similar reports he received from many others, but they made no great impression nor caused any interruption in his occupation or study, and as soon as the season for the concerts was over, and the mould, &c., in readiness, a day was set apart for casting, and the metal was in the furnace, but unfortunately it began to leak at the moment when ready for pouring, and both my brothers and the caster with his men were obliged to run out at opposite doors, for the stone flooring (which ought to have been taken up) flew about in all directions, as high as the ceiling. My poor brother fell, exhausted with heat and exertion, on a heap of brickbats. Before the second casting was attempted, everything which could ensure success had been attended to, and a very perfect metal was found in the mould, which had cracked in the cooling.

“But a total stop and derangement now took place, and nearly six or seven months elapsed before my brother could return to the undisturbed enjoyment of his instruments and observations. For one morning in Passion week, as Sir William Watson was with my brother, talking about the pending journey to town, my eldest nephew^[9] arrived to pay us a visit, and brought the confirmation that his uncle was expected with his instrument in town. A chaise was at the door to take us to Bristol for a rehearsal in the forenoon, of the ‘Messiah,’ which was to be performed the same evening. The conductor being still lost in conversation with his friend, was obliged to trust to my poor abilities for filling the music box with the necessary parts for between ninety and one hundred performers. My nephew had travelled all night, but we took him with us, for we had not one night in the week, except Friday, but what was set apart for an oratorio either at Bath or Bristol. Soon after Easter a new organ being erected in St. James’s Church, it was opened with two performances of the ‘Messiah;’ this again took up some of my brother’s time....

... The Tuesday after Whit Sunday, May 8th, my brother left Bath to join Sir William Watson at his father’s in Lincoln’s Inn Fields, furnished with everything necessary for viewing double stars, of which the first catalogue had just then appeared in the ‘Philosophical Transactions.’ A new seven-foot stand and steps were made to go in a moderate sized box, to be screwed together on the spot where wanted. Flamsteed’s Atlas, in which the stars had during the winter been numbered, catalogues of double stars, micrometers, tables, &c., and everything which could facilitate reviewing objects, had been attended to in the preparation for the journey.

“But when almost double the time had elapsed which my brother could safely be absent from his scholars, Alex, as well as myself, were much at a loss how to answer their inquiries, for, from the letters we received, we could learn nothing but that he had been introduced to the King and Queen, and had permission to come to the concerts at Buckingham House, where the King conversed with him about astronomy.”

It was during his absence at this time that the three following letters were written and received:—

Dear Lina,—

I have had an audience of His Majesty this morning, and met with a very gracious reception. I presented him with the drawing of the solar system, and had the honour of explaining it to him and the Queen. My telescope is in three weeks’ time to go to Richmond, and meanwhile to be put up at Greenwich, where I shall accordingly carry it to-day. So you see, Lina, that you must not think of seeing me in less than a month. I shall write to Miss Lee myself; and other scholars who inquire for me, you may tell that I cannot wait on them till His Majesty shall be pleased to give me leave to return, or rather to dismiss me, for till then I must attend. I will also write to Mr. Palmer to acquaint him with it.

I am in a great hurry, therefore can write no more at present. Tell Alexander that everything looks very likely as if I were to stay here. The King inquired after him, and after my great speculum. He also gave me leave to come to hear the Griesbachs play at the private concert which he has every evening. My having seen the King need not be kept a secret, but about my staying here it will be best not to say anything, but only that I must remain here till His Majesty has observed the planets with my telescope.

Yesterday I dined with Colonel Walsh, who inquired after you. There were Mr. Aubert and Dr. Maskelyne. Dr. Maskelyne in public declared his obligations to me for having introduced to them the high powers, for Mr. Aubert has so much succeeded with them that he says he looks down upon 200, 300, or 400 with contempt, and immediately begins with 800. He has used 2500 very completely, and seen my fine double stars with them. All my papers are printing, with the postscript and all, and are allowed to be very valuable. You see, Lina, I tell you all these things. You know vanity is not my foible, therefore I need not fear your censure. Farewell.

Dear Lina,—

I pass my time between Greenwich and London agreeably enough, but am rather at a loss for work that I like. Company is not always pleasing, and I would much rather be polishing a speculum. Last Friday I was at the King’s concert to hear George play. The King spoke to me as soon as he saw me, and kept me in conversation for half an hour. He asked George to play a solo-concerto on purpose that I might hear him; and George plays extremely well, is very much improved, and the King likes him very much. These two last nights I have been star-gazing at Greenwich with Dr. Maskelyne and Mr. Aubert. We have compared our telescopes together, and mine was found very superior to any of the Royal Observatory. Double stars which they could not see with their instruments I had the pleasure to show them very plainly, and my mechanism is so much approved of that Dr. Maskelyne has already ordered a model to be taken from mine and a stand to be made by it to his reflector. He is, however, now so much out of love with his instrument that he begins to doubt whether it deserves a new stand. I have had the influenza, but am now quite well again. It lasted only five or six days, and I never was confined with it.... There is hardly one single person here but what has had it.

I am introduced to the best company. To-morrow I dine at Lord Palmerston’s, next day with Sir Joseph Banks, &c., &c. Among opticians and astronomers nothing now is talked of but what they call my great discoveries. Alas! this shows how far they are behind, when such trifles as I have seen and done are called great. Let me but get at it again! I will make such telescopes, and see such things—that is, I will endeavour to do so.

The letter ends abruptly with this sentence, and only one more was written during this momentous interval.

Dear Carolina,—

I have been so much employed that you will not wonder at my not writing sooner. The letter you sent me last Monday came very safe to me. As Dr. Watson has been so good as to acquaint you and Alexander with my situation, I was still more easy in my silence to you. Last night the King, the Queen, the Prince of Wales, the Princess Royal, Princess Sophia, Princess Augusta, &c., Duke of Montague, Dr. Heberden, M. de Luc, &c., &c., saw my telescope, and it was a very fine evening. My instrument gave general satisfaction. The King has very good eyes, and enjoys observations with telescopes exceedingly.

This evening, as the King and Queen are gone to Kew, the Princesses were desirous of seeing my telescope, but wanted to know if it was possible to see without going out on the grass, and were much pleased when they heard that my telescope could be carried into any place they liked best to have it. About 8 o’clock it was moved into the Queen’s apartments, and we waited some time in hopes of seeing Jupiter or Saturn. Meanwhile I showed the Princesses, and several other ladies who were present, the speculum, the micrometers, the movements of the telescope, and other things that seemed to excite their curiosity. When the evening appeared to be totally unpromising, I proposed an artificial Saturn as an object, since we could not have the real one. I had beforehand prepared this little piece, as I guessed by the appearance of the weather in the afternoon we should have no stars to look at. This being accepted with great pleasure, I had the lamps lighted up which illuminated the picture of a Saturn (cut out in pasteboard) at the bottom of the garden wall. The effect was fine, and so natural that the best astronomer might have been deceived. Their royal highnesses and other ladies seemed to be much pleased with the artifice.

I remained in the Queen’s apartment with the ladies till about half after ten, when in conversation with them I found them extremely well instructed in every subject that was introduced, and they seemed to be most amiable characters. To-morrow evening they hope to have better luck, and nothing will give me greater happiness than to be able to show them some of those beautiful objects with which the heavens are so gloriously ornamented.

Sir William Watson returned to Bath after a fortnight or three weeks’ stay. From him we heard that my brother was invited to Greenwich with the telescope, where he was met by a numerous party of astronomical and learned gentlemen, and trials of his instrument were made. In these letters he complained of being obliged to lead an idle life, having nothing to do but to pass between London and Greenwich. Sir William received many letters which he was so kind as to communicate to us. By these, and from those to Alexander or to me, we learned that the King wished to see the telescope at Windsor. At last a letter, dated July 2, arrived from Therese, and from this and several succeeding ones we gathered that the King would not suffer my brother to return to his profession again, and by his writing several times for a supply of money we could only suppose that he himself was in uncertainty about the time of his return.

In the last week of July my brother came home, and immediately prepared for removing to Datchet, where he had taken a house with a garden and grass-plot annexed, quite suitable for the purpose of an observing-place. Sir Wm. Watson spent nearly the whole time at our house, and he was not the only friend who truly grieved at my brother’s going from Bath; or feared his having perhaps agreed to no very advantageous offers; their fears were, in fact, not without reason.... The prospect of entering again on the toils of teaching, &c., which awaited my brother at home (the months of leisure being now almost gone by), appeared to him an intolerable waste of time, and by way of alternative he chose to be Royal Astronomer, with a salary of £200 a year. Sir William Watson was the only one to whom the sum was mentioned, and he exclaimed, “Never bought monarch honour so cheap!” To every other inquirer, my brother’s answer was that the King had provided for him.

Everything was immediately packed for the removal, and on the 1st of August, when the brothers and sister walked over to Datchet from Slough (where the coach passed), they found the waggon, with its precious load of instruments, as well as household furniture, waiting to be unpacked. The new home was a large neglected place, the house in a deplorably ruinous condition, the garden and grounds overgrown with weeds. For a fortnight they had no female servant at all; an old woman, the gardener’s wife, showed Miss Herschel the shops, where the prices of everything, from coals to butcher’s meat, appalled her. But these considerations weighed for nothing in her brother’s eyes against the delight of stables where mirrors could be ground, a roomy laundry, which was to serve for a library, with one door opening on a large grass-plot, where “the small twenty-foot” was to be erected; he gaily assured her that they could live on eggs and bacon, which would cost nothing to speak of now that they were really in the country!

The beginning of October, Alexander was obliged to return to Bath. The separation was truly painful to us all, and I was particularly affected by it, for till now I had not had time to consider the consequence of giving up the prospect of making myself independent by becoming (with a little more uninterrupted application) a useful member of the musical profession. But besides that my brother William would have been very much at a loss for my assistance, I had not spirit enough to throw myself on the public after losing his protection.

Poor Alexander! we had hoped at first to persuade him to change Bath for London, where he had the offer of the most profitable engagements, and we should then have had him near us ... but he refused, and before we saw him again the next year he was married.

Much of my brother’s time was taken up in going, when the evenings were clear, to the Queen’s Lodge to show the King, &c., objects through the seven-foot. But when the days began to shorten, this was found impossible, for the telescope was often (at no small expense and risk of damage) obliged to be transported in the dark back to Datchet, for the purpose of spending the rest of the night with observations on double stars for a second Catalogue. My brother was besides obliged to be absent for a week or ten days for the purpose of bringing home the metal of the cracked thirty-foot mirror, and the remaining materials from his work-room. Before the furnace was taken down at Bath, a second twenty-foot mirror, twelve-inch diameter, was cast, which happened to be very fortunate, for on the 1st of January, 1783, a very fine one cracked by frost in the tube. I remember to have seen the thermometer 1½ degree below zero for several nights in the same year....

... In my brother’s absence from home, I was of course left solely to amuse myself with my own thoughts, which were anything but cheerful. I found I was to be trained for an assistant-astronomer, and by way of encouragement a telescope adapted for “sweeping,” consisting of a tube with two glasses, such as are commonly used in a “finder,” was given me. I was “to sweep for comets,” and I see by my journal that I began August 22nd, 1782, to write down and describe all remarkable appearances I saw in my “sweeps,” which were horizontal. But it was not till the last two months of the same year that I felt the least encouragement to spend the star-light nights on a grass-plot covered with dew or hoar frost, without a human being near enough to be within call. I knew too little of the real heavens to be able to point out every object so as to find it again without losing too much time by consulting the Atlas. But all these troubles were removed when I knew my brother to be at no great distance making observations with his various instruments on double stars, planets, &c., and I could have his assistance immediately when I found a nebula, or cluster of stars, of which I intended to give a catalogue; but at the end of 1783 I had only marked fourteen, when my sweeping was interrupted by being employed to write down my brother’s observations with the large twenty-foot. I had, however, the comfort to see that my brother was satisfied with my endeavours to assist him when he wanted another person, either to run to the clocks, write down a memorandum, fetch and carry instruments, or measure the ground with poles, &c., &c., of which something of the kind every moment would occur. For the assiduity with which the measurements on the diameter of the Georgium Sidus, and observations of other planets, double stars, &c., &c., were made, was incredible, as may be seen by the various papers that were given to the Royal Society in 1783, which papers were written in the daytime, or when cloudy nights interfered. Besides this, the twelve-inch speculum was perfected before the spring, and many hours were spent at the turning bench, as not a night clear enough for observing ever passed but that some improvements were planned for perfecting the mounting and motions of the various instruments then in use, or some trials were made of new constructed eye-pieces, which were mostly executed by my brother’s own hands. Wishing to save his time, he began to have some work of that kind done by a watchmaker who had retired from business and lived on Datchet Common, but the work was so bad, and the charges so unreasonable, that he could not be employed. It was not till some time afterwards in his frequent visits to the meetings of the Royal Society (made in moonlight nights), that he had an opportunity of looking about for mathematical workmen, opticians, and founders. But the work seldom answered expectation, and it was kept to be executed with improvements by Alexander during the few months he spent with us.

The summer months passed in the most active preparation for getting the large twenty-foot ready against the next winter. The carpenters and smiths of Datchet were in daily requisition, and as soon as patterns for tools and mirrors were ready, my brother went to town to have them cast, and during the three or four months Alexander could be absent from Bath, the mirrors and optical parts were nearly completed.

But that the nights after a day of toil were not given to rest, may be seen by the observations on Mars, of which a paper, dated December 1, 1783, was given to the Royal Society. Some trouble also was often thrown away during those nights in the attempt to teach me to re-measure double stars with the same micrometers with which former measures had been taken, and the small twenty-foot was given me for that purpose.... I had also to ascertain their places by a transit instrument lent for that purpose by Mr. Dalrymple, but after many fruitless attempts it was seen that the instrument was perhaps as much in fault as my observations.

July 8.—I began to use the new Newtonian small sweeper, (for a description of this instrument see note to Neb. No. 1, V. class, at the end of the catalogue of first 1000 Neb. and Cl.), but it could hardly be expected that I should meet with any comets in the part of the heavens where I swept, for I generally chose my situation by the side of my brother’s instrument, that I might be ready to run to the clock or write down memorandums. In the beginning of December I became entirely attached to the writing-desk, and had seldom an opportunity after that time of using my newly-acquired instrument.

My brother began his series of sweeps when the instrument was yet in a very unfinished state, and my feelings were not very comfortable when every moment I was alarmed by a crack or fall, knowing him to be elevated fifteen feet or more on a temporary cross-beam instead of a safe gallery. The ladders had not even their braces at the bottom; and one night, in a very high wind, he had hardly touched the ground before the whole apparatus came down. Some labouring men were called up to help in extricating the mirror, which was fortunately uninjured, but much work was cut out for carpenters next day.

That my fears of danger and accidents were not wholly imaginary, I had an unlucky proof on the night of the 31st December. The evening had been cloudy, but about ten o’clock a few stars became visible, and in the greatest hurry all was got ready for observing. My brother, at the front of the telescope, directed me to make some alteration in the lateral motion, which was done by machinery, on which the point of support of the tube and mirror rested. At each end of the machine or trough was an iron hook, such as butchers use for hanging their joints upon, and having to run in the dark on ground covered a foot deep with melting snow, I fell on one of these hooks, which entered my right leg above the knee. My brother’s call, “Make haste!” I could only answer by a pitiful cry, “I am hooked!” He and the workmen were instantly with me, but they could not lift me without leaving nearly two ounces of my flesh behind. The workman’s wife was called, but was afraid to do anything, and I was obliged to be my own surgeon by applying aquabusade and tying a kerchief about it for some days, till Dr. Lind, hearing of my accident, brought me ointment and lint, and told me how to use them. At the end of six weeks I began to have some fears about my poor limb, and asked again for Dr. Lind’s opinion: he said if a soldier had met with such a hurt he would have been entitled to six weeks’ nursing in a hospital. I had, however, the comfort to know that my brother was no loser through this accident, for the remainder of the night was cloudy, and several nights afterwards afforded only a few short intervals favourable for sweeping, and until the 16th January there was no necessity for my exposing myself for a whole night to the severity of the season.

I could give a pretty long list of accidents which were near proving fatal to my brother as well as myself. To make observations with such large machinery, where all around is in darkness, is not unattended with danger, especially when personal safety is the last thing with which the mind is occupied; even poor Piazzi^[10] did not go home without getting broken shins by falling over the rack-bar, which projects in high altitudes in front of the telescope, when in the hurry the cap had been forgotten to be put over it.

In the long days of the summer months many ten- and seven-foot mirrors were finished; there was nothing but grinding and polishing to be seen. For ten-foot several had been cast with ribbed backs by way of experiment to reduce the weight in large mirrors. In my leisure hours I ground seven-foot and plain mirrors from rough to fining down, and was indulged with polishing and the last finishing of a very beautiful mirror for Sir William Watson.

An account of the discoveries made with the twenty-foot and the improvements of the mechanical parts of that instrument during the winter of 1785, is given with the Catalogue of the first 1000 new nebulæ. By which account it must plainly appear that the expenses of these improvements, and those which were yet to be made in the apparatus of the twenty-foot (which in fact proved to be a model of a larger instrument), could not be supplied out of a salary of £200 a year, especially as my brother’s finances had been too much reduced during the six months before he received his first quarterly payment of fifty pounds (which was Michaelmas, 1782). Travelling from Bath to London, Greenwich, Windsor, backwards and forwards, transporting the telescope, &c., breaking up his establishment at Bath and forming a new one near the Court, all this, even leaving such personal conveniences as he had for many years been used to, out of the question, could not be obtained for a trifle; a good large piece of ground was required for the use of the instruments, and a habitation in which he could receive and offer a bed to an astronomical friend, was necessary after a night’s observation.

It seemed to be supposed that enough had been done when my brother was enabled to leave his profession that he might have time to make and sell telescopes. The King ordered four ten-foot himself, and many seven-foot besides had been bespoke, and much time had already been expended on polishing the mirrors for the same. But all this was only retarding the work of a thirty or forty-foot instrument, which it was my brother’s chief object to obtain as soon as possible; for he was then on the wrong side of forty-five, and felt how great an injustice he would be doing to himself and to the cause of Astronomy by giving up his time to making telescopes for other observers.

Sir William Watson, who often in the lifetime of his father came to make some stay with us at Datchet, saw my brother’s difficulties, and expressed great dissatisfaction. On his return to Bath he met among the visitors there several belonging to the Court (among the rest Mde. Schwellenberg), to whom he gave his opinion concerning his friend and his situation very freely. In consequence of this my brother had soon after, through Sir J. Banks, the promise that £2000 would be granted for enabling him to make himself an instrument.

Immediately every preparation for beginning the great work commenced. A very ingenious smith (Campion), who was seeking employment, was secured by my brother, and a temporary forge erected in an upstairs room.
