Trees; Shrubs; Forests and forestry. LXVIII. .SALICA^CEiE : PO'PULUS. 821 bracteas of the fertile flowers are, also, more deeply and regularly cut. The branches are more upright and compact. The leaves are rounder, more conspicuously 3-ribbed, and less deeply or acutely lobed; not folded in the bud, and without gum. They are downy beneath ; but the down is chiefly greyish, and not so white or cottony as in P. 41ba: in some instances the leaves are glabrous. (Smith.) A tree closely resenibhng the preceding species, and found in similar situations. The wood of the white poplar weighs, when green, 581b. 3oz. per cubic foot; and in a dried state, 38 lb. 7 oz.: it shrinks and cracks considerably in drying, losing one quarter of its bulk. The wood of P. (a.) canescens is said to be much harder and more durable'than that of P. alba; in the same manner as the wood of the TiWa europae'a parvifolia is finer-grained and harder than that of T. e. grandifolia. The wood of both kinds is the whitest of the genus; and it is used, in France and Germany, for a variety of minor purposes, par- ticularly when lightness, either of weight or colour, is thought desirable; or where an artificial colour is to be given by staining. It is excellent for form- ing packing-cases, because nails may be driven into it without its sphtting. It is used by the turner and the cabinet-maker, and a great many toys and small articles are made of it. The boards and rollers around which pieces of silk are wrapped in merchants' warehouses and in shops are made of this wood, which is peculiarly suitable for this purpose, from its lightness, which prevents it much increasing the expense of carriage. The principal use of the wood of the white
