The elements of forestry : designed to afford information concerning the planting and care of forest trees for ornament or profit and giving suggestions upon the creation and care of woodlands with the view of securing the greatest benefit for the longest time, particularly adapted to the wants and conditions of the United States. Forests and forestry. 202 French Method of procurmg Turpentine. and under this a small earthern jar, glazed on the inside and shaped like a flower-pot, is placed. 806. About once a week the cutting is renewed, by taking off a thin slice of wood a little deeper and an inch or two higher up, and this is renewed through the warm season, and from year to year. There are two or more of these incisions on each tree, but never wider than at first begun. They are carried up till they are twelve or fifteen feet high, but there is always left a strip of bark, at least as wide, between them. Gradually the wood grow- ing only under this bark, will close over the incisions, generally leav- ing a deep crevice to show its place. This wood is again cut into long, narrow bands as be- fore, aud so for a long period. 807. The general growth of the tree is cheeked, but the quality of the wood improved by this process. It appears to hasten its maturity, and it no doubt shortens its life; but such trees are kept in productiou from the age of twenty years till they are fifty or sixty years old. It L«, however, generally more profitable to cut them when of good size for timber, to make room for those that are com- ing up from self-seeding, and that will be more productive. 808. As the incisions extend up, the earthern jars are hung higher up, and they are emptied from time to time. The whitish opaque incrustation is scraped off in the fall, and the jars are left bottom upwards at the foot of the tree till spring. The work of "resinage" is commonly done upon shares, and a division is made between the proprietor and the " remieur," after the
