820 EXPERIMENT STATION RECORD. 



"Exclusive of the rice-producing States, the Territory of Hawaii, and Indian res- 

 ervations, the number of irrigators in the United States in 1899 was 108,218, an 

 increase of 54,082, or 100 per cent, over the number reported in 1889. The number 

 of acres irrigated was 7,539,545, an increase during the 10 years of 3,908,165, or 

 107.6 i^er cent. Of the total irrigated area, 5,944,412 acres were in crops, and the 

 total value of the products therefrom was $86,860,491. The total cost of construction 

 of the irrigation systems operated in 1899 was $67,770,942. ... In the number of 

 irrigators California stands far ahead of any other State, having about one-fourth of 

 the total number in the United States. Colorado, however, exceeds in the number 

 of acres irrigated, although not in the value of irrigated crops." 



Of the total irrigated area, 7,093,629 acres were watered from streams, and 169,644 

 acres from wells. The number of acres in crops irrigated in 1899 was 5,711,965, and 

 the number of irrigated acres in pasture and unmatured crops was 1,551,308. The 

 Talue of the irrigated crops was $84,433,438. ... Of the irrigated area, 7,263,273 

 acres was in the arid States, 273,117 acres in the semiarid region, and 3,155 in the 

 himiid region.
