AN ECONOMIC STUDY OF THE PRODUCTION OF CANNING CROPS 41 



FlG. 3 . LOCATION OF FACTORIES CANNING TOMATOES, 

 AND AVERAGE LENGTH OF GROWING SEASON 



Each dot represents a factory where tomatoes are packed, as 

 reported in the Canners' Directory for 1920. 



The lines are drawn thru points having the average length of 

 growing season indicated. (From thesis of R. A. Mordoff, The 

 Climate of New York State and Its Relation to Agriculture) 



from frost which these lakes give, makes a growing season long enough so 

 that tomatoes can be grown safely. 



Data on the cost of producing tomatoes were obtained by both the 

 survey and the accounting method in three areas Orleans County, 

 Niagara County, and Chautauqua and Erie Counties. The last-named 

 section is designated in the following discussion as the Chautauqua area. 

 The location of these areas is shown in figure 4. The number of farms on 

 which cost figures were obtained by each method is given in table 39:
