 northern division on the 15th, though the high point was reached in the 

 central and southern divisions on the 5th. It was during the 6-day 

 period, 13th-18th, that corn made its best progress, but during most of 

 the month the deficient temperature and sunshine made its progress very 

 slow. At the close of the month, less than two-thirds of the crop was 

 safe from on ordinary killing frost; and part of that was susceptible to 

 serious damage by freezing temperatures. It was most backward in the 

 northeastern one-third of the State and nearly all safe in the extreme
