EEPOET OF THE SECEETARY OF AGEICULTUEE. XLIII 



Cooperation with State Institutions. 



During the year this Bureau has cooperated, as far as possible, with 

 State institutions, including experiment stations, boards of agricul- 

 ture, and geological surveys; also with Bureaus and Divisions of this 

 Department, as well as with other Departments of the Government. 

 Such cooperation has been particularly close with the North Carolina 

 department of agriculture and with the Illinois experiment station, 

 both of which institutions have contributed money toward the expenses 

 of the soil survey in their respective States. In other States the 

 cooperation has been just as cordial, but the institutions have not 

 been able to render financial assistance. Their advice has been sought 

 and given wherever possible in arranging for and in the carrying on 

 of the work, and the work has been done, as far as possible, with the 

 ultimate object of being of service to the State institutions in the 

 prosecution of more detailed work. The Utah experiment station has 

 cooperated in the line of drainage investigations and has contributed 

 valuable assistance and advice in the work that has been started at 

 Salt Lake City. The Connecticut experiment station and the Penn- 

 sylvania experiment station have continued their cooperation in the 

 tobacco investigations with credit and profit to all of the institutions 

 concerned. 



The Bureau of Soils, through its laboratories, its soil survey, and its 

 other lines of investigation, has cooperated with and has helped other 

 Bureaus and Divisions in the Department, and has cooperated with 

 the War Department in furnishing an assistant to organize a soil 

 survey in the Philippine Islands, and in furnishing assistants to inspect 

 the soils of some of the military posts and to advise as to the treat- 

 ment in the establishment of parade grounds, a matter which is of 

 considerable importance, involving the expenditure of large sums of 

 money where the natural soils are not suited to the formation of a 

 permanent sod. 



Progress and Cost of the Soil Survey. 



The area surveyed and mapped during the fiscal year was 14,541 

 square miles, or 9,306,240 acres, and the. area previously reported as 

 having been surveyed was 8,082 square miles, making a total of 22,623 

 square miles, or 14,478,720 acres. This work was carried on during 

 the year in twenty-five States and Territories and in Porto Rico. 



The following table shows the total area surveyed during the fiscal 

 year 1902, together with that previously reported, in each of the thirty 

 States and Territories in which the soil survey work has been carried 

 on. This work has been uniforml}^ done on a scale of 1 inch to the 

 mile, and the maps have been published or are ready for publication. 

 This table does not include any areas in which work of reconnoissance 

 merely has been done, but only areas in which actual soil surveys 

 have been made and soil maps prepared.
