delphia and Wilmington, a fourth dearer than that of either the red or the 

 scarlet oak : the leather is said to be improved by the addition of a small quan- 

 tity of the bark of the hemlock spruce." (N. Amcr. Syl.,1. p. 80.) This species 

 of oak is used in New Jersey to form hedges. The elder Michaux says that, for 

 this purpose, the acorns are sown on a raised bank ; and that they must be 

 carefully defended, during the first winter, from rats and moles, which are fond 

 of them. The young plants must be kept clear of weeds, and earthed up 

 during the two following years ; and, in the course of the fourth, they will 

 form a very thick and strong hedge ; the young shoots and branches crossing 

 and 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 kind 

 will last more than a century. {Hist, des Chenes, No. 14.) This species ap- 

 pears from the Hortus Kcwensis, 2d ed., to have been introduced, under the 

 name of Q. elongata, by Mr. Murdock Murchison, in 1763; and to have been 

 reintroduced, under the name of Q. triloba, by the Messrs. Fraser, in 1800. 

 There are plants at Messrs. Loddiges's, under the name of Q. lyrata, as well 

 as that of Q. falcata ; and there is a tree at Trentham called Q. falcata, which 

 is 20 ft. high, diameter of the trunk 1 1 in., and of the head 18 ft. Phalae'na

 stigma Fab. Ent., 4. p. 424. ; the orange white-spot moth ; feeds upon the 

 leaves of this oak and Q. tinctoria. In a young state the whole brood of cater- 

 pillars keep together, but disperse as they grow larger. It is very seldom 

 seen on the wing. One observed by Abbott went into the ground on the 20th 

 of September, and came forth on the 16th of June. Both the larva and imago 

 are of a bright orange colour.
