Mean Temperature. (Plate IV Map V.) 
Taking up now the temperature of the state, we find a normal 
range of 6° F., — from 49 0 F. in the extreme north to above 55 0 
F. in the south. The annual isotherms vary quite regularly with 
the latitude excepting in the north-central part of the state as the 
map will show. 
Extreme Maximum Temperature. (Plate IV Map VI.) 
The highest temperature is normally reached in the latter part 
of July. The only station differing from this was Milligan 
with a maximum of ioo° F. on August 11. The other fourteen 
stations ranged in extreme maxima from ioo° at Portsmouth 
down to 92 0 at Greenville and 93 0 at Ashtabula. 
Extreme Minimum Temperature. (Plate IV Map VII.) 
The extreme minimum temperatures vary by twice as many 
degrees as do the extreme maximum. At Portsmouth the aver- 
age of lowest records is one degree below zero, while Montpelier 
averages thirteen below and Milligan eighteen below zero. The 
time of the coldest averages is about January 24 at Columbus, 
this being the earliest, and February 7, at Ashtabula. As has 
been previously shown by Prof. Moseley in his “Sandusky 
Flora," ice drifting eastward in Lake PJrie may prolong the cold 
season at points toward the eastern end of the Lake. This prob- 
ably explains the lateness of the records of extremes at Ashta-
