Gardening. COLORADO COLORADO 355 â¢which are in great part utilized as hay ranches and for stock ranges. The following figures regarding acreage are from the report of the state engineer for the year 1890. The total is given as approximately 66,560,000 acres. East of the continental divide lie 40,800,000 acres, and on the west 25,760,000 acres. Of the area east of the divide, one-third, or 10,200,000 acres, lies within the mountains and the remainder, 30,600,000 acres, con- sists of plain and valley lands. On the western slope the proportion of mountain and plain is reversed, there being 16,360,000 acres within the mountains and about 9,400,000 acres of plain and valley lands. For the western slope the rainfall is given as 33 inches for the mountains and for the plains and valleys, and for the eastern slope as 30 inches for the mountains and 15 inches for the plains. The tillable lands of the state are in the main out- side the mountains, and the average annual rainfall on these lands is near 13 inches for the whole state. This rainfall comes mainly in the mouths of April, May and June, the precipitation for the other months being usually very small. It fol- lows,from the small rainfall, that crops can only be suc- cessfully grown by irriga- tion, and it is this idea that has dominated the agricul- ture and horticulture of the state ever since the begin- ning, nearly forty years ago. Irrigation being a necessity, the lands useful for ag- ricultural purposes would be those reasonably level tracts bordering the streams, and extending back only as far as the water can be carried. The first ditches were constructed cheaply, and for the irrigation of first bottom lands only. A little later th
