excessive rain for a short period of the month and no rain the rest of 
the month.

The dates of the last killing frost in the spring and of the first 
killing frost in the fall in 1919 are shown in Table 4. These data are 
of importance in comparing the length of the growing season in the 
different sections studied.

The 1919 yields on the farms studied were within 10 per cent of the 
average yield for the five preceding years in all areas excepting that 
of Monroe County, N. Y., where the 1919 yield was only 72 per cent 
of the normal. The low yield in this county was due primarily to 
the fact that the early part of the season was very wet and the latter 
part dry. 
CROPS AND LIVE STOCK PRODUCED. 
The area devoted to different crops in 1919 on the farms studied is 
shown in Table 5. Sixteen per cent of the crop acreage was devoted 
to potatoes, and for the several regions this percentage varied from 
12 in Grand Traverse County, Mich., to 28 in Aroostock County, Me.
