New York AGRICULTURAL EXPERIMENT STATION. 189 
We find also that there is approximate uniformity in the aver- 
age temperature of the soils for these seven months at the differ- 
ent depths observed, as follows: 
Average temperature for seven months. 
At 1 inch, 2 inch. 3 inch. 6 inch. 9 inch. 12 inch, 18 inch. 24 inch. 
62.3° Cig sed bs 61.5° 60.1° 59.3° 59.0° 61:35 59.4° 
The average rainfall at the Station for twelve years has been 
27.73 inches, with a maximum of 36.88 and a minimum of 22.29, 
but generally it has been uniform, and as will be seen by Table 
78, very uniformly distributed. During the seven months, April 
to October, inclusive, the average rainfall has been 2.86 inches 
per month, and during the 12 years of observation there have 
been but two years in April, May and September, and but one 
year in October when the rainfall has been less than one inch. 
During the 12 years the average precipitation during the months 
November to March, inclusive, has been 1.47 inches per month, 
with a maximum of 1.77 and a minimum of 1.21 inches. 
During the 10 years of observation, as will be seen by refer- 
ence to Table 79, the average sunshine record for the seven 
months, April to October, inclusive, has shown 45.7 per cent. of 
possible sunshine, @. ¢., during these months the sun, while above 
the horizon, has been obscured by cloud a little more than one- 
half the time, the maximum sunshine having been 54.5 per cent. 
of possible, and the minimum 38.8 per cent. During the five 
months, November to March, inclusive, the average of possible 
sunshine has been 27 per cent., with a maximum of 33.7 and a 
minimum of 19.1 per cent. of the possible. 
It will be seen that we are favored especially by having the 
sunshine as also the rainfall when it is most needed for our crops. 
The average of the standard air thermometer (see Table 81), 
‘gives for 10 years, for the months April to October, inclusive, 
an average temperature of 60.7° F., while for the months No- 
~ vember to March, inclusive, the average has been 28.9° F. 
Table 82 gives the monthly average from April to October, 
inclusive, of soil temperatures at 7 a. m., 12m. and 6 p.m, for 
different depths and for 12 years. Also in same table the gen- 
eral daily average for each depth and each month. 
It will be observed that the average daily observations taken 
at 12m. is higher for depths of one and two inches than the
