Tables I and II give the results of the analysis of some soil 
samples from the Gulf coast and the Atlantic coast. I am in- 
debted to Dr. A. G. McCa tt, of the University of Maryland, for the 
Maryland samples, and also for the information in regard to the 
productivity of the soils. Little information was obtainable in 
regard to the samples of table I, except that they came from soils

taken is fairly productive, being capable of producing ten bushels
