From this bulletin it will be seen how much below normal the 
precipitation was during the growing season both years, except for 
very heavy rains during May, 1910 , from which there was necessarily 
a heavy run off. . 
The lateness of calving contributed to the lack of weight in the 
calves when brought in. 
November 5 th the calves were separated from the cows, after 
having become accustomed to hay, and were fed hay and a small 
amount of barley until June 3 , 1911 . The following summary shows 
results.
