Very generally, the States have created agricultural experiment stations and model farms, drainage districts in the South, a levee system on the Mississippi River, and irrigation districts in the West; artesian wells in Texas, and in several States, State dairy bureaus. In specialized products, such as beet sugar, there is often provision for a State agricultural bureau, and nearly always for general agricultural as well as industrial instruction. The States are only beginning to adopt State forests, or forest reserves, Massachusetts and New York leading the way. Forestry commissions exist in a few States, but the very slightest beginning has been made at forestry laws. No control is as yet exercised over reforestation or replanting; a few of the Western States exempt growing trees, or the land covered by growing trees, from more than a nominal tax, notably Indiana and Nebraska. The forestry laws are, however, increasing. In 1903 we find one, in 1904 five, and in 1905 six, with the tree bounty law in North Dakota, and two States exempting forest lands from taxes. There are four statutes this year for fish or game preserves. In 1907 four States create forestry boards, and two exempt forests from taxation, and in 1908 growing trees are exempted in Massachusetts and Rhode Island. But under the unlimited power of Congress over Federal territory not yet incorporated into States, or not ceded to the State when incorporated, it is to the Federal government that we have looked for the creation and preservation of parks, forest reserves, and natural reserves generally. How far it may constitutionally create such within the lines of old States, or on land of which it is otherwise incapable of ownership, is a constitutional question still undecided.
