pine. The plot was in corn in 1901 and had been under cultivation 

 but the one year. Fertilizer was added that year as follows : Acid phos- 

 phate and nitrate of soda at the rate of 250 and -100 pounds per acre, 

 respectively. Corn was grown on the plot instead of the cereals used in 

 other cases, which were secured too late. The data for this crop are 

 not yet complete. The corn crop suffered from insects. Soil is not 

 alkali; was not irrigated. 



Geologically the soil is of the Lamentian system and is formed prin- 

 cipally by the decomposition of granites, gneisses, and schists, but has 

 been modified to some extent by the influence of water. The soil has 

 been termed a sandy loam to a depth of 7 inches, and is underlaid by 

 clay. The top soil contains from 40 to 60 per cent of quartz fragments, 

 varying in size from a sand grain to double fists, the most common size 

 being from 2 to 3 mm. in diameter. 



Washington State, Soil No. 41. The native vegetation is bunch grass. 

 The plot has been in wheat stubble and has been under cultivation fif- 

 teen years. In 1901 wheat was grown, also in 1900. In 1899, peas ; 

 in 1898, wheat; and in 1897, vetch. 



Season was very favorable ; crops not injured by insects or disease. 

 Soil is not alkali ; was not irrigated. Geologically a decomposed basalt, 

 volcanic origin, evidently wind-drifted. No sand in it. 



Wyoming, Soil No. 47. At this station the crops were killed by a frost 

 in July. The native vegetation is Western blue stem and other grasses. 

 In 1901 the plot was sown in winter wheat and killed by hail. In 1900 

 the crop was oats ; in 1899, 1898, and 1897, alfalfa was grown, giving 

 3 to 4 tons each year. The soil is not alkali ; is irrigated. 



The season was so unfavorable that no results were obtained, except 

 in early grains and potatoes. 



New Mexico, Soil No. 49. The seed were received very late for plant- 

 ing and failed to make any crops. The native vegetation is tomillo, 

 mesquite, and cachania. In 1901 the plot had been in rape ; in 1900, 

 corn; in 1899, millet; and in 1898 and 1897, alfalfa. No fertilizer had 

 been used. The soil is not alkali ; is irrigated. Geologically it is a 

 silt deposited by the Rio Grande.
