Elephants have almost disappeared; now and then a stray one comes. Figs are still a great nuisance, but the greatest anxiety among planters is regarding beetles. You will be sorry to hear that the first year the trees showed fruit or flower, one-tenth of them were destroyed by the beetle; the insects still go on destroying, and hardly a tree attacked ever recovers.

This is a very serious evil, and upon which the fortunes of all those involved in coco-nut planting depend. The trees come into bearing but very slowly, and I consider no estate will give any return over its current expenses under twelve years. It takes twelve months from the formation of the flower, till the fruit ripens. On an estate, perhaps one of the oldest and best in this district, out of 120 acres, part seven and eight years old, about 12 per cent, are in flower or in bearing, and give a return of about twenty-four nuts per tree, on an average, yearly. On the next oldest, the return is not near so great. But few of the estates here will, I think, pay interest on the money laid out, and many will never pay anything over the expense of keeping them up, even after coming into bearing. I doubt if any estate in this district, however economically managed, will ever give a net return of more than £2, or perhaps of £2 10s. per acre, at least without there is a great increase in the consumption of oil in Europe. The consumption of this oil, in Europe, is under 5,000 tons. If the beetles do not destroy half the trees, the estates here when in bearing, if they yield anything, will give half that quantity; and it must be borne in mind that coco-nut oil is not a strong oil, like palm oil, and that soap boilers will never use it to any extent, for it will allow but little admixture of rosin, &c.; its use in Europe will be principally for candles and fancy soaps; but as by refining and compression they can now purify tallow, and make of it candles fully equal to those made from coco-nut oil, the consumption of the latter is not likely to increase. The consumption of candles is always limited on the continent of Europe, liquid oil being preferred, and in many instances gas is now being used where candles formerly were.

On a rough estimate—for an actual enumeration has not been lately taken—the total number of bearing trees in Pinang may be stated at 50,000, and those in Province Wellesley at 20,000; but very large accessions to these numbers have of late years been made. The tree is partial to a sandy soil in the vicinity of the sea, and Province Wellesley offers, therefore, greater facilities, perhaps, for its cultivation than Pinang does, as its line of clear beach is longer, and has many narrow slips of light or sandy land lying betwixt the alluvial flats inland. There are several kinds of this tree known here; one has a yellowish color, observable both on the branches and unripe fruit; its branches do not droop much. A second has green spreading branches, more drooping than the former, the fruit being green colored until ripe; this is, perhaps, the most prolific; it also bears the soonest, if we except the dwarf coco-nut, which fruits at the second or third year, before the stem has got above one foot high. This last kind was brought from Malacca; it attains in time to the height of the common sort. Its fruit is small and round, and of course less valuable than the other sorts. There is also a coco-nut so saturated with green, that the oil expressed from its kernel partakes of that color.

It is a mistaken supposition that the coco-nut tree will flourish without care being taken of it. The idea has been induced by the luxuriant state of trees in close proximity to houses and villages, and in small cove's where its roots are washed by the sea. In such circumstances, a tree, from being kept clear about the roots, from being shaded, and from occasional stimuli, advances rapidly to perfection; but in an extended plantation, a regular and not inexpensive system of culture must be followed to ensure success.

The nuts being selected, when perfectly ripe, from middle-aged trees of the best sorts, are to be laid on the ground under shades, and after the roots and middle shoots, with two branches, have appeared, the sooner they are planted the better. Out of 100 nuts, only two-thirds, on an average, will be found to vegetate. The plants are then to be set out at intervals of thirty or forty feet—the latter if ground can be spared—and the depth will be regulated by the nature of the soil, and the nut must not be covered with earth. The plants require, in exposed situations, to be shaded for one and even two years, and no lalang grass must be permitted to encroach on their roots. A nursery must be always held in readiness to supply the numerous vacancies which will occur from deaths and accidents. The following may be considered the average cost of a plantation, until it comes into bearing:—

The cultivators of Kiddah adopt a very slovenly expedient for collecting the fruit. Instead of climbing the tree in the manner practised by the natives on the Coromandel coast, by help of a hoop passing round the tree and the body of the climber—and a ligature so connecting the feet as will enable him to clasp the tree with them—the Malays cut deep notches or steps in the trunk, in a zig-zag manner, sufficient to support the toes or the side of the foot, and thus ascend with the extra, aid only of their arms. This mode is also a dangerous one, as a false step, when near the top of a high tree, generally precipitates the climber to the ground. This notching cannot prove otherwise than injurious to the tree. But the besetting sin of the planter of coco-nuts, and other productive trees, is that of crowding. Coco-nut trees, whose roots occupy, when full grown, circles of forty to fifty feet in diameter, may often be found planted within eight or ten feet of each other; and in the native campongs all sorts of indigenous fruit trees are jumbled together, with so little space to spread in, that they mostly assume the aspect of forest trees, and yield but sparing crops.

The common kinds of the coco-nut, under very favorable circumstances, begin to bear at six years of age; but little produce can be expected until the middle or end of the seventh year. The yearly produce, one tree with another, may be averaged at 80 nuts the tree; where the plantation is a flourishing one—assuming the number of trees, in one hundred orlongs, to be 5,000—the annual produce will be 400,000 nuts, the minimum local market value of which will be 4,000 Spanish dollars, and the maximum 8,000 dollars. From either of these sums 6 per cent. must be deducted for the cost of collecting, and carriage, &c. The quantity of oil which can be manufactured from the above number of nuts will be, as nearly as possible, 834 piculs of 133⅓ lbs.

The Chinese, who are the principal manufacturers of the oil, readily give a picul of it in exchange for 710 ripe nuts, being about 563 piculs of oil out of the total produce of the plantation of 100 orlongs. The price of coco-nut oil has been so high in the London market as £35 per tun, or about an average of ten dollars per picul. It is said that English casks have not been found tight enough for the conveyance of this oil to Europe, but if the article is really in great demand, a method will no doubt be discovered to obviate this inconvenience.

So long, however, as the cultivator can obtain a dollar and a half, or even one dollar for 100 nuts, he will not find it profitable to make oil, unless its price greatly rises.

Soap is manufactured at Pondicherry from this oil, but it is not seemingly in repute; the attempt has not been made in Pinang with a view to a market.

There is scarcely any coir rope manufactured at this island, so that the profit which might (were labor cheaper) arise from this application of the coco-nut fibre, is lost. The shell makes good charcoal; the leaves are scarcely put to any purpose, the nipah or attap being a superior material for thatching.

The coco-nut tree is extremely apt to be struck by lightning, and in such cases it is generally destroyed. It is a dangerous tree, therefore, to have close to a house. If the trees are widely planted, coffee may be cultivated under their shade. It is generally believed that the extracting of toddy from this tree hastens its decline. The Nicobar and Lancavi Islands used partly to supply the Pinang market with this indispensable article; but their depopulation has greatly reduced the quantity.

On the whole it may be said that there is no cultivation which insures the return of produce with so much certainty as that of the coco-nut tree; and as Rangoon, the Tenasserim coast, and Singapore will, probably, always remain good markets for the raw nut, there appears to be every chance of the value of the produce affording ample remuneration to the planter.

"As an agricultural production, the culture of peppermint in the United States is limited to few localities; this county and the adjoining ones, Seneca and Ontario, comprise the largest bed. In the year 1846 about 40,000 lbs. of oil were produced. In Lewis county, in this state, it is grown, though to a less extent; the amount of oil produced there in 1846 was estimated at 4,500 lbs. In Michigan about 10,000 lbs. are annually produced; Ohio furnishes about 3,000 lbs. and Indiana 700 lbs. per annum. The entire crop in the United States, in the year 1846, is estimated in round numbers at 58,000 lbs.

The above comprises all the localities of any importance in the United States, and the above estimates of the annual product of oil were made from correct data for the year 1846, since which time the cultivation of mint has rapidly decreased in consequence of a speculative movement by a New York company, who in the spring of 1847 purchased nearly all the mint then growing in this State, and stipulated with the growers not to raise it for two years thereafter, which condition was generally observed on the part of the growers. The present year (1849), on account of the drought, has not realised the expectations of those engaged in its culture, although the amount of oil produced is much larger than the product of the two preceding years. In this mint district, 8,000 lbs. have been raised; Lewis county furnishes 1,000 lbs.; Michigan, 8.000 lbs.; Ohio, 1,000 lbs., and Indiana 500 lbs. So that the entire crop of 1849 will not materially vary from 18,500 lbs.

I have consulted several of the principal dealers in mint oil, whose opportunities have been ample to form a tolerably correct estimate of the amount of oil annually consumed, and their opinion fixes the total consumption, for the various purposes for which it is used in the United States and in Europe, at from 20,000 to 30,000 lbs. annually.

The price of mint oil is extremely fluctuating. Like other unstaple commodities, the value of which depends upon their scarcity or abundance, it never has assumed a constant and standing value, but its price has generally been deranged by speculation and monopoly. It has happened that the amount of oil produced was for several years greater than the annual consumption, producing an accumulation in the market, and reducing the price to the very low rate of 75 cents per pound; on the other hand, when the article was scarce, it readily sold for 5 dollars 25 cents per pound. The average price for fifteen vears has been about 2 dollars 50 cents, per pound. This year (1849) it readily sells for 1 dollar 50 cents., (6s. 6d.).

Peppermint began to be cultivated in this vicinity as an agricultural product about the year 1816, but for several years the want of a proper knowledge of its culture, and the expense and difficulty of extracting the oil, prevented its extension beyond a few growers, who, however, realised fortunes out of the enterprise. Almost any kind of soil that will successfully rear wheat and maize is adapted to the growth of mint. Rich alluvions, however, seem to be most natural, as would be inferred from the fact that the wild herb is almost uniformly found growing upon the tertiary formations on the margins of streams. The rich bottom lands along our rivers and the boundless prairies of the West are eminently adapted for its successful culture. It is believed by those best acquainted with the subject, that its cultivation must be ultimately confined to the western prairies, where it will grow spontaneously, and where the absence of noxious weeds and grasses, incident to all older settled lands, renders the expense of cultivation comparatively light, and where the low price of land will be an important item in the amount of capital employed, the expense of marketing being slight in comparison to that of the more bulky products of agricultural industry.

The two following years no labor is bestowed upon the crop, though it is sometimes benefited by ploughing over the whole surface, very shallow, in the autumn of the second year, and harrowing lightly the following spring, which frequently renews the vigor of the plant and increases the product.

The mint should be cut as soon as it is in full bloom, and the lower leaves become sere; the first crop will not be fit to cut as early as the two succeeding ones. It is then to be hayed and put in cock, and is then ready for distillation.

I have consulted many mint growers, who have cultivated it for a series of years, in regard to the average yield per acre, and have arrived at the following estimate, which I think is low, provided the land is suitable, and is properly cultivated. I estimate the average yield per acre for the first year at 18 lbs.; the second year at 14 lbs.; and the third year at 8 lbs.—making the product for three years 40 lbs., which I think will not materially vary from the actual result, though growers aver they have raised from 30 to 40 lbs. per acre the first season.

Several years since, the only method of extracting the oil then known was by distilling the herb in a copper kettle, or boiler, and condensing in the usual manner; a slow and tedious process, by which about 12 or 15 pounds of oil could be separated in a day. But recently steam, that powerful agent, which has wrought such immense changes in our social and national economy, has been applied to this subject with its usual attendant success. The present method consists in the use of a common steam-boiler, of the capacity of from 100 to 150 gallons, from which the steam is conveyed by conductors into large wooden air-tight tubs, of 200 gallons capacity, containing the dried herb; from which it is conveyed, charged with the volatile principle of the plant, into a water-vat, containing the condenser. The water collected at the extremity of the condenser, although it does not readily commingle with the oil, is highly tinctured with it, and is used to feed the boiler. Two tubs are necessary, in order that when the "charge" is being worked off in one, the other can be refilled. The oil is then to be filtered, and is ready for market. The expense of a distillery is estimated at 150 dollars, which, with the labor of two men, and a cord of dry wood, will run 40 lbs. of oil per day. The usual price for distilling is 25 cents per pound.

The cost of production is of course greatly modified by circumstances. If grown on rich bottom lands, or prairie, unusually free from weeds and grass, the labor required will be comparatively trifling. From information derived from the principal mint growers in this vicinity, I have prepared the following estimate of the cost of production of an acre of mint for three years:—
