HOLLY, (Ilex aquifolium,) is a very clean, fine-grained wood, the whitest and most costly of those used by the Tunbridge-ware manufacturer, who employs it for a variety of his best works, especially those which are to be painted in water colours. It is closer in texture than any other of our English woods, and does not readily absorb foreign matters, for which reason it is used for painted screens, the squares of draft-boards, and for the stringings or lines of cabinet-work, both in the white state and when dyed black, also for some of the inside works of piane-fates, harps, for calico-printers' blocks, &a When larger wood than holly is required, the horse-chesnut is employed, but the latter is much softer.

The holly requires very particular care in its treatment: Immediately it is felled it is prepared into pieces of the form ultimately required, as planks, veneers, or round blocks for turning. The veneers are hung up sepa-rately to dry, as resting in contact even for two or three hours would stain them; the round blocks are boiled in plain water for two or three hours, and on removal from the copper they are thrown in a heap and closely covered up with sacking to exclude the air, which would otherwise cause them to split The heap is gradually exposed as it dries; at the end of about four weeks the pieces look greenish, and are covered with mildew sometimes as thickly as one-sixteenth of an inch; this is brushed off at intervals of three or four weeks, and in about six months the wood is fit for use.

Holly is a remarkably tough clean wood, and is used for chucks; but this troublesome preparation to whiten the wood, (and which is not generally practised on other woods,) is not then required, although a good boil hastens the extraction of the sap, and the subsequent seasoning of the wood. Birdlime is prepared from the middle bark of the Holly.

There is an American species of this genus, the Ilex opaca, opaque-leaved or American holly, of which the wood is employed in turnery and cabinet making; there are other species in the Himalayas.
