Mountain type. The relatively light seasonal rainfall and the heavy 

 soils of the Dunkirk and Ontario series have resulted in the survival of 

 Rural varieties at the expense of other types. Here, as on Long Island, 

 Irish Cobbler was found to be the leading early variety. 



The status of varietal types in this region is summarized in table 39 : 



TABLE 39. SUMMARY OF TYPES ON 300 MONROE COUNTY FARMS IN 1912 AND 1913 



The year 1913 was one of low seasonal rainfall in Monroe County, 

 and the crop suffered from the drought. As shown in table 39, varieties 

 of the Green Mountain group yielded, in that year, an average of about 

 15 bushels per acre less than those of the Rural type, in spite of the use of 

 more seed and about the same amount of fertilizer. This is further evi- 

 dence that varieties of the Green Mountain group, which set tubers earlier 

 than do those of the Rural group, suffer the effects of reaching their 

 critical growth period during the drought season of midsummer in Monroe 

 County. 



Potato varieties in Franklin and Clinton Counties 



Altho more varieties are grown in Franklin and Clinton Counties than 

 on Long Island, this region is similar to the lLong Island area in that 

 nearly all the varieties were found to be of the Green Mountain type, 

 as is shown in table 40. A notable absence of early varieties was found 

 among those grown from 1912 to 1914, inclusive. This may be explained 

 in general by the fact that the possibilities for profitable yields are much 

 greater in the main crop varieties. 



The four Green Mountain varieties listed at the head of table 40 White 

 Beauty, Selfic Beauty, World's Fair, and Immense comprised more than 

 half of the average total acreage of this region during the three years con- 

 cerned. Type has become well standardized here, as the list shows only 

 four varieties of the Rural, or blue-sprout type, the remainder all being 

 of the Green Mountain, or white-sprout, type. While these four Rural 

 varieties are standard varieties, their average yield per acre and extent of
