delphia and Wilmington, a fourth dearer than that of either the red or thescarlet oak : the leather is said to be improved by the addition of a small quan-tity of the bark of the hemlock spruce.” (N. Amer. Syl., i. p. 80.) This speciesof oak is used in New Jersey to form hedges. The elder Michaux says that, forthis purpose, the acorns are sown on a raised bank; and that they must becarefully defended, during the first winter, from rats and moles, which are fondof them. The young plants must be kept clear of weeds, and earthed upduring the two following years; and, in the course of the fourth, they willform a very thick and strong hedge ; the young shoots and branches crossingand intertwining with, each other. If kept properly pruned and weeded,and the gaps filled up by young plants raised in boxes, a hedge of this kindwill last more than a century. {Hist, des Chines, No. Id.) This species ap-pears from the Hortus Kewensis, 2d ed., to have been introduced, under thename of Q. elongata, by Mr. Murdock Murchison, in 1763; and to have beenreintroduced, under the name of Q. triloba, by the Messrs. Fraser, in 1800.There are plants at Messrs. I.oddiges’s, under the name of Q. lyrata, as wellas that of <2- falcata ; and there is a tree at Trentham called Q. falcata, whichis 20 ft. high, diameter of the trunk 11 in., and of the head 18 ft.

In a young state the whole brood of cater-pillars keep together, but disperse as they grow larger. It is very seldomseen on the wing. One observed by Abbott went into the ground on the 20thof September, and came forth on the 16th of June. Both the larva and imagoare of a bright orange colour.
