Remarks.

The English, Chestnut, Durmast, or Red Oak, Q. robur var. sessiliflora, distinguished by long leaf stalks and short acorn stalks, affords practically similar but lower-rated wood. The two varieties supply the British Oak of commerce. Dantzic, Rigi, and some other European oaks take names from port of shipment. Rubrus is red, but robur is a noun meaning strength; the adjective robustus means "oaken" or vigorous. [p027]

PLATE 6. WHITE ASH (Fraxinus americana).

ASH. (Fraxinus.)

Ash is widely distributed over the temperate regions of the northern hemisphere, and occurs in the tropics, on the island of Cuba. The tree has occupied a position second only to that of oak. Our Teutonic forefathers relied upon its wood for boats and weapons. Their ancient faith connects it with the creation of the original man. It is often associated with oak in country proverbs.[21] Europeans regard the trees for ornamental purposes, but Americans value them for wood.

White Ash
(Fraxinus americana).

Ash and oak woods resemble one another in that there are bands of open pores in both woods, but the pith-rays of the ash are thinner and scarcely discernible. Ash is coarser, less attractive, easier to work, tough, elastic, and somewhat lighter than oak. It seasons well, but does not last when exposed to the weather. Lumbermen separate the woods into white and black ash, the former including the lighter-colored and more desirable pieces. This commercial division is also a botanical one in the North, where the only species of any note are the white ash and black ash (F. americana and F. nigra). The Southern green ash (F. lanceolata) is usually classed as white ash. The trees that grow up after the cutting of the virgin forest afford tougher, more pliable, but not necessarily stronger pieces, known as "second-growth" ash. Although not relied upon for out-of-door construction, ash is one of the most important of the cheaper cabinet woods and is used in stairs, furniture, and similar works. [p028]

One half of the thirty known species of the genus Fraxinus inhabit North America. [p029]

FOOTNOTES

[21] A tradition, old in Pliny's time, is that serpents avoid ash trees; another is that ash is particularly liable to be struck by lightning. (Keeler.)

The name ash is also applied to several species of the genus Pyrus or Sorbus, to which the apple, pear, quince, and some other trees belong. "Mountain Ash" is either Pyrus americana or Pyrus sambucifolia. Both species, with their bright red berries, are to be classed as shrubs rather than trees; their light, soft, weak, close-grained woods having no economic importance, save perhaps for fuel. The series is partially as follows:

The Toothache Trees, Xanthoxylum americana and Xanthoxylum clava-herculis (Linn.), are known as ash and prickly ash. The gopher wood, Cladrastis tinctoria, is yellow ash. These woods are not important.
