Planting may be done in the spring or fall, the latter being often preferable in regions where a dry season occurs early in the summer. For plantations of broadleaf species, one-year-old seedlings are best suited, while coniferous species should be two to three years old. The chief points to remember in setting out the trees are not to allow the roots, particularly of coniferous trees, to dry out; to dig the holes large enough to enable the roots to take a normal position without doubling up, and to pack the soil firmly around them. Where planting is done on open ground, it is highly advantageous to plow and harrow the soil before setting out the trees in order to preserve the moisture and kill weeds and sod.
Willows, cottonwoods and other poplars are very easily propagated from cuttings. Cuttings should be of strong, healthy wood of the previous season's growth which ripened well and did not shrivel during the winter. A good length is 8 to 12 inches, with the upper cut just above a bud. They may be made when wanted and planted with a spade, or if the ground is mellow they can be merely shoved into the soil until only one bud is above the surface and then tramped.
The spacing of the trees is a question largely of utility, with some variation for different species. In general, however, close planting is advisable in treeless regions, since an artificial forest must stand in a dense mass if it is to succeed in the struggle against native vegetation, wind, sunshine, frost and dry weather. A single tree or row unprotected by associates has a poorer chance. Cultivation is the best method of conserving soil moisture. To obtain the best results plantations should be cultivated, if possible, at least during the first few years. The less care the trees are to have, the thicker they should be set in order that they will be close enough to establish forest conditions of shade, litter and underbrush. Thinnings can then be made as they grow and need more room. The material thus obtained will provide an early supply of fuel, stakes and posts. A spacing of 4x4 feet is common, but this does not allow for cultivation. For this reason 2x8 feet is preferable. Shelter belts should be planted closely in order to give protection quickly.
COST
The cost of planting is not great. Broadleaf seedlings will cost from $1 to $6 per thousand at the nursery, coniferous plants $2.50 to $10. If grown at home the cost will be greatly reduced. The preparation of the soil by plowing and harrowing should not exceed $2 per acre, and planting from $2.50 to $5 per thousand, according to the species, the method used and the condition of the soil.

TAX REFORM TO PERMIT REFORESTATION
LOSS IN IDLE LAND
It is of the very highest importance to have that part of our constantly increasing area of cut and burned over forest land which is not more valuable for agriculture put to its only useful purpose—the growing of another forest crop. If this is done it will continue to be a source of tax revenue, to employ labor and support industry, to supply our forest needs, to bring revenue into the state, and to protect our streams. Otherwise it will become a desert, non-taxable, non-productive, a fire menace, and in every way worse than a dead loss to the state in which it exists and to the country at large. In the one way it will be of use to every citizen, whatever his occupation; in the other it will be a burden upon every citizen.
