be located. It is stated that nearl\' all availaljle water of the .streams 

 of the State has already been appropriated, so that an increased suppl}- 

 for the future can be secured only from underground sources. "Arte- 

 sian basins are numerous in Wyoming", and some of them are very large 

 and especiall}' well located." Twelve such basins are described in tliis 

 bulletin, namely, the Big Horn, the Shoshone, Powder River, Green 

 Kivei", Sweetwater Valley, Laramie, the Shirley, Cheyenne, the Car- 

 bon, the Uinta, the Gros Ventre, and the Teton. No systematic 

 attempts to dcn^elop the water resources of these basins have been 

 made, but. "judging from the source of the water in many of the 

 Wyoming basins, the artesian wells in this State should equal any that 

 have been drilh^l in South Dakota."

 a smaller percentage of salts than that of the previous year (E. S. R., 

 10, p. 930), due to the fact that a compact alluvial soil was used and 

 percolation was slower. The greatest loss of nitrogen in the drain- 

 age occurred in case of bare soil, the order of losses in other cases 

 l)eing (1) soil ])earing young red clover, (2) that under Hax and beans, 

 and (8) that under summer grain. Lime was the constituent most 

 easily removed from the soil. The losses of potash and soda were 

 ])racti(*ally the same. Chlorin and sulphuric acid were I'emoved in 

 considerable quantities, especially in bare soil. l*hosphoric acid could 

 scarcely l)e detected in the drainage water of soils heai'ing ci'op^. In 

 bare soils traces wei-c found.

 analyses and pot tests of 26 samples of two classes of soils — light and 

 heavy — are reported in detail. The lime content of the soils examined 

 varied from 0.092 to 1.271 per cent. The average for light soils was 

 0.333 per cent; for heavy soils, 0.(;91. The average percentage of 

 carbon dioxid was 0.052 per cent in light soils and 0.09(S in heavy soils, 

 the average for 22 of the samples being 0.015. In case of the light 

 soils 25.7 per cent of the lime was in the form of carbonate; in caseof 

 heavy soils, 19. 1 per cent. While a high percentage of carbon dioxid 

 usually indicated a high percentage of lime in the soil, a small ])ercent- 

 age of carbon dioxid did not always iii(licat»> a low lime content. Cal- 

 cium humate was found in appreciable amounts only in a few cases. 

 The solubility of the lime in 2 percent hydrochloi'icacid varied in case 

 of the light soils fi'om 3S.5 to 92 p(>r cent, averaging (iS.l* j)er cent; in 

 case of heavv soils, from ♦!().('» to 90.2 ])er cent, a\'eraging 78.4 per
