New York districts. The rest of the late-producing areas applied no 

 fertilizer whatever. 



In the majority of these districts man labor and horse labor, 

 manure, seed, and fertilizer constituted 72 per cent or more of the 

 total cost of producing potatoes exclusive of land rent. These 

 results have been computed on the basis of normal yield.
