I have a firm faith that all the great deserts of the Temperate and Torrid Zones will yet be reclaimed by irrigation and tree-planting. The bill which Congress did not pass, nor really consider, whereby it was proposed, some years since, to give a section of the woodless Public Lands remote from settlement to every one who, in a separate township, would plant and cherish a quarter-section of choice forest-trees, ought to have been passed--with modifications, perhaps, but preserving the central idea. Had ten thousand quarter-sections, in so many different townships of the Plains, been thus planted to timber ten to twenty years ago, and protected from fire and devastation till now, the value of those Plains for settlement would have been nearly or quite doubled. A capital mistake, it seems to me, is being made by some of the dairy farmers of our own State. One who has a hundred acres of good soil, whereof twenty or thirty are wooded, cuts off his timber entirely, calculating that the additional grass that he may grow in its stead will pay for all the coal he needs for fuel, so that he will make a net gain of the time he has hitherto devoted each Winter to cutting and hauling wood. He does not consider how much his soil will lose in Summer moisture, how his springs and runnels will be dried up, nor how the sweep of harsh winds will be intensified, by baring his hill-tops and ravines to sun and breeze so utterly. In my deliberate judgment, a farm of one hundred acres will yield _more_ feed, with far greater uniformity of product from year to year, if twenty acres of its ridge-crests, ravine-sides, and rocky places, are thickly covered with timber, than if it be swept clean of trees and all devoted to grass. Hence, I insist that the farmer who sweeps off his wood and resolves to depend on coal for fuel, hoping to increase permanently the product of his dairy, makes a sad miscalculation.
