In regard to the reference on page 31 of "Food for 

 Plants," the figures given by Professor G. E. Bailey, 

 Author of Bulletin No. 24, of the California State 

 Mining Bureau, are merely selected to express the 

 highest maximum equivalent amount of Nitrate of 

 Soda which may be removed by the largest crops taken 

 from any soil in one season. It is not intended to 

 thereby recommend that the same amount of Nitrate 

 of Soda should be put on the soil broadcast each 

 season, but merely to show the great rate at which 

 the soil exhaustion of Nitrates proceeds. 



On page 79 of "Food for Plants," the value of 

 the Hay cut on the small plots does not refer to the 

 amount of produce per acre, but merely to the values 

 obtained from the crops on the plots themselves. 

 Full information is given on this point in Bulletins of 

 the Rhode Island Station.
