Resolutions were adopted covering the entire subject of conservation as shown in one of them as follows: "We agree that the land should be so used that erosion and soil-wash shall cease; that there should be reclamation of arid and semi-arid regions by means of irrigation, and of swamps and overflowed regions by means of drainage; that the waters should be so conserved and used as to promote navigation, to enable the arid regions to be reclaimed by irrigation, and to develop power in the interests of the people; that the forests which regulate our rivers, support our industries, and promote the fertility and productiveness of the soil should be preserved and perpetuated; that the minerals found so abundantly beneath the surface should be so used as to prolong their utility; that the beauty, healthfulness, and habitability of our country should be preserved and increased; that the sources of national wealth exist for the benefit of the people, and that monopoly thereof should not be tolerated."
It is not possible to prevent this entirely, but much of the loss might have been avoided by leaving the hilltops, which are never well fitted for cultivation, covered with forests. In this way the soil-wash from above is prevented and the streams run gently and with only a small amount of muddy deposit, forming proper drainage for the soil.
If this soil is worth a dollar a ton, it is probable that the total loss of fertility from soil-wash to the farmers and forest-owners of the United States is not far from a billion dollars a year.
The preserving of the forests on the great mountain ranges of the country, where nature has placed them, will mean in the one matter of soil-wash, fruitful lands and bountiful harvests, instead of barren, wasted lands, desolated by floods and seamed by great ravines, carrying desolation to the lands below them. But in many cases the trees are already cut away.
Here replanting becomes necessary and should be done in every case where soil-wash is beginning on the mountain tops. It is almost equally desirable to plant small shrubs and bushes as an undergrowth, so that the roots may form a thick mat below the ground to hold the water in the soil, and permit it to filter through slowly.
Soil-wash should be lessened by planting trees and shrubs along the banks; and where overflow or erosion lowers the value of the land or repeatedly ruins the crops, dykes and levees should be built. The rivers most important commercially should be improved first.
