118 REPORT OF OFFICE OF EXPERIMENT STATIONS. 



soiling crops, beets, etc. Work is going on with grade dairy cows 

 bred to Holstein, Jersey, Guernsey, and Shorthorn bulls. The station 

 now has the first generation of progeny, and it is believed that in 

 four generations animals can be produced practically equivalent to 

 pure breds. The department is doing some work with beef cattle 

 and sheep, and is also raising calves in different ways. Experiments 

 on the amounts of unground corn and oats voided by cows, heifers, 

 and calves showed that from 20 to 26 per cent of the material passed 

 through the digestive tract undigested, indicating that the feeding 

 of grain without grinding can seldom if ever be economical. Dried 

 beet pulp is being fed as a substitute for silage, and cooperative 

 experiments are under way with farmers in the use of beet pulp for 

 cows as a supplement to failing jDastures. 



The horticultural department has begun the selection of strains 

 of potatoes resistant to blight. Studies of the cross pollination of 

 varieties of apples and pears have been continued, as have also those 

 of the pollination of strawberries as a means of improving the ship- 

 ping qualities and prolonging the season. There is some work with 

 fertilizers, catch crops, and tillage of orchards, and cooperative 

 spraying trials for grape rot, San Jose scale, and potato rot are 

 proceeding at several points in the State.
