When fires are held in check by special enactments, such as those which have been passed in Victoria and South Australia, and the waters of the winter streams retained for summer use by tanks and dams; when artesian wells are frequent and irrigation general, belts of timber will become possible upon the plains. Once planted, these will in their turn mitigate the extremes of climate, and keep alike in check the forces of evaporation, sun, and wind. Cultivation itself brings rain, and steam will soon be available for pumping water out of wells, for there is a great natural store of brown coal and of oil-bearing shale near Denver, so that all would be well were it not for the locusts--the scourge of the plains--the second curse. The coming of the chirping hordes is a real calamity in these far-western countries. Their departure, whenever it occurs, is officially announced by the governor of the State. I have seen a field of indian-corn stripped bare of every leaf and cob by the crickets; but the owner told me that he found consolation in the fact that they ate up the weeds as well. For the locusts there is no cure. The plovers may eat a few billions, but, as a rule, Coloradans must learn to expect that the locusts will increase with the increase of the crops on which they feed. The more corn, the more locusts--the more plovers, perhaps; a clear gain to the locusts and plovers, but a dead loss to the farmers and ranchmen. The Coloradan “boys” are a handsome, intelligent race. The mixture of Celtic and Saxon blood has here produced a generous and noble manhood; and the freedom from wood, and consequent exposure to wind and sun, has exterminated ague, and driven away the hatchet-face; but for all this, the Coloradans may have to succumb to the locusts. At present they affect to despise them. “How may you get on in Colorado?” said a Missourian one day to a “boy” that was up at St. Louis. “Purty well, guess, if it warn‘t for the insects.” “What insects? Crickets?” “Crickets! Wall, guess not--jess insects like: rattlesnakes, panther, bar, catamount, and sichlike.” “The march of empire stopped by a grasshopper” would be a good heading for a Denver paper, but would not represent a fact. The locusts may alter the step, but not cause a halt. If corn is impossible, cattle are not; already thousands are pastured round Denver on the natural grass. For horses, for merino sheep, these rolling table-lands are peculiarly adapted. The New Zealand paddock system may be applied to the whole of this vast region--Dutch clover, French lucern, could replace the Indian grasses, and four sheep to the acre would seem no extravagant estimate of the carrying capability of the lands. The world must come here for its tallow, its wool, its hides, its food.
