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 5th 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.
