Aids to Solution of Soil Problems. The soil survey conducted by 

 the Bureau of Soils of the United States Department of Agriculture, in 

 co-operation with the various state departments of agriculture or agri- 

 cultural experiment stations, is now extended into many counties in every 

 state. Two kinds of surveys have been made: (1) that known as the 

 reconnoissance soil survey, in which detailed mapping is not undertaken 

 (it consists chiefly in mapping the soil series) ; and (2) a detailed county 

 survey showing the location and extent of each soil type. The results 

 of this work are issued as government reports, accompanied by colored 

 maps outlining the soils. In these reports the soils are fully described 

 and their crop adaptations stated. Much other valuable data pertaining 

 to agricultural conditions, climate and soil requirements are also given. 

 These reports are available to all farmers living in the districts in which 

 the surveys are made. They may be secured either through the local 

 senator or representative, or directly from the National Department of 

 Agriculture. In some cases the state experiment station or state depart- 

 ment of agriculture will be able to supply them. 



The detailed county surveys will enable any one in such an area to 

 ascertain the types of soil on his farm. If there is any doubt in this partic- 

 ular on the part of the farmer, he can submit samples of his soil to his 

 state experiment station, and by giving the exact location of his farm, 

 the authorities at the station w;ll be able to advise him not only as to the
