Choice of species.—While we speak of a timber crop as one, there is quite as much variety possible in timber crops as in Not only are there many different kinds of wood, each distinct qualities and fit for distinct employment, but there are dif- ferences of treatment which pro- duce differences of result. There are the conifers,—pines, spruces, hemlocks, firs, larch, cedar and the like,—which furnish building ma- terials and grow from seed only (with few ), requiring a long time to make suitable size for the purpose for which they are best fitted; and there are the broad-leaf trees of great variety, hard and soft woods, fit for a variety of purposes, and often becoming available for use sooner than the con- ifers, capable of reproduction by sprouting from the stump (coppice) as well as by seed. Whether it be in the man- agement of an established woodlot or the starting of a new plantation, a choice of species and method of treat- ment must be made from the first, with the object clearly in view that the crop is to serve. Limitations as to output.—We have started to consider the woodlot as destined, in the first place, to supply domes- tic needs of fuel and small-dimen- sion material; but the question may arise whether it could not be managed with a view to supplying the general market. By general market we mean the requirements of sawmills and lumber - yards. Excepting special cases, the far- mers' woodlot is not well fitted for the practice of commercial forestry,—the growing of timber for the general market. The reasons for this inapti- tude are partly economic, partly r;\^ ,-'", based on the natural history of ;'' . forest-growth, and on silvicultural peculiarities. Wood is a crop which, unlike other farm crops, does not have a physical maturity
