Page 89 - August, inclusive, from 4 to 5 inches, while cleared areas which are uncultivated probably absorb from 7 to 8 inches. Forests, then, not only use less water than cultivated areas, but they further tend to increase the summer flow of streams by holding back the water in accumulations of leaves, mosses and forest litter, until it can be gradually absorbed into the soil. If we examine in detail the figures as to runoff of the Hudson river in comparison...

Page 80 - Surveyor for 1893 and 1894, where estimates of the cost of the several dams are also given in detail. Referring to the estimates, it appears that at site No. 1, in Mount Morris Canyon, a dam raising the water surface 130 feet would cost, if built of concrete alone, $2,450,000, but if built with sandstone faces throughout, except for the spillway, where granite is provided, the estimated cost would become $2,590,000. A dam of the same height at site No. 2, if built throughout of concrete, would cost...
Page 52 - Thus the quartz gives 436 and 516 pounds in seven and twenty-eight days, respectively, while the sand, 1 to 1, is only 363 and 442 pounds for seven and twenty-eight days, respectively. At 3 to 1, 4 to 1 and 5 to 1, the quartz and sand are practically equal, although there is a slight superiority of the sand in the 5 to 1 mixture. An explanation of these interesting results is offered when we examine the column of fineness in Table No. 1, from which it...

Page 76 - Raised packer gradually, packing it at every few feet by setting pressure above against pressure of water from below. In this way the hole was tested for its entire length and found to stand, as stated, 100 pounds at the bottom, and from 40 to 50 pounds in the upper part.
Page 89 - Rye requires from 0.091 to .... Oak trees require from 0.038 to 0.035 Potatoes require from 0.038 to 0.055 Fir trees require from 0.020 to 0.043 Applying these figures, we learn that ordinary farm crops may take up from 12 to 15 inches of water over the whole area cropped during the growing period. Forests in the same way may take up in their growing period from April to August, inclusive, from 4 to 5 inches, while cleared areas which are uncultivated probably absorb from 7 to 8 inches. Forests,...

On disconnecting, water ran from pipe for one hour and forty-nine minutes. This outflowing water showed coloring matter for fifteen minutes.
