During the field season of 1902, 17,996 square miles or 11,517,440 acres were sur- 

 veyed and mapped on a scale of 1 in. to the mile. Prior to that year the total area 

 surveyed and mapped was 15,871 square miles or 10,157,440 acres. The average cost 

 of the work in 1902 was $1.93 per square mile. The accounts of the individual sur- 

 veys include, as heretofore, data relating to the location, history, topography, physi- 

 ography, geology, climate, agricultural conditions, type soils, and crop adaptations. 



Soil survey from Arecibo to Ponce, Porto Rico, C. W. Dorset, L. Mesmer, 

 and T. A. Caine {Porto Rico Sta. Bui. 3, j)p. 53, pfe. 4, fig- 1, map 1). — This bulletin, 

 of which there are both English and Spanish editions, is a reprint from Report of 

 Field Operations of the Bureau of Soils of this Department for 1902 (see above). 

 The area reported upon extends 5 miles each side of the proposed government road 

 from Arecibo to Ponce, and embraces many types of soil which are represented in 

 other parts of the island. The report deals with location and boundaries of the area, 

 history of settlement and agricultural development, climate, physiography and 

 geology, water supply for irrigation, underground water and drainage, alkali in soils, 

 and agricultural methods and conditions, and maps, and gives results of detailed sur- 

 veys, including notes on crop adaptations of 18 type soils found in the area. 



"Washington soils, E. Fulmer {Washington Sta. Bui. 55, pp. 5;^').— Chemical 

 analyses of 25 soils from eastern Washington and 54 from western Washington, made 

 by the same methods and with the same oliject in view as in previous investigations 

 (E. S. R., 7, p. 375), are reported. The results confirm the conclusions drawn from 

 the earlier analyses.
