The eastern and western portions of the plains are not alike. In Kansas the grass is tall and rank; the ravines are filled with cottonwood, hickory, and black walnut; here and there are square miles of sunflowers, from seven to nine feet high. As we came west, we found that the sunflowers dwindled, and at Denver they are only from three to nine inches in height, the oddest little plants in nature, but thorough sunflowers for all their smallness. We found the buffalo in the eastern plains in the long bunch-grass, but in the winter they work to the west in search of the sweet and juicy “blue grass,” which they rub out from under the snow in the Coloradan plains. This grass is crisp as hair, and so short that, as the story goes, you must lather before you can mow it. The “blue grass” has high vitality: if a wagon train is camped for a single night among the sunflowers or tall weeds, this crisp turf at once springs up, and holds the ground forever. The most astounding feature of these plains is their capacity to receive millions, and, swallowing them up, to wait open-mouthed for more. Vast and silent, fertile yet waste, fieldlike yet untilled, they have room for the Huns, the Goths, the Vandals, for all the teeming multitudes that have poured and can pour from the plains of Asia and of Central Europe. Twice as large as Hindostan, more temperate, more habitable, nature has been placed here hedgeless, gateless, free to all--a green field for the support of half the human race, unclaimed, untouched, awaiting smiling, hands and plow. There are two curses upon this land. Here, as in India, the rivers depend on the melting of distant snows for their supplies, and in the hot weather are represented by beds of parched white sand. So hot and dry is a great portion of the land, that crops require irrigation. Water for drinking purposes is scarce; artesian bores succeed, but they are somewhat costly for the Coloradan purse, and the supply from common wells is brackish. This, perhaps, may in part account for the Western mode of “prospecting” after water, under which it is agreed that if none be found at ten feet, a trial shall be made at a fresh spot. The thriftless ranchman had sooner find bad water at nine feet than good at eleven. Irrigation by means of dams and reservoirs, such as those we are building in Victoria, is but a question of cost and time. The never-failing breezes of the plains may be utilized for water-raising, and with water all is possible. Even in the mountain plateau, overspread as it is with soda, it has been found, as it has been by French farmers in Algeria, that, under irrigation, the more alkali the better corn crop.
