The figures given above by each station may be compared with 

 each other for that station. Only in a general way should those from 

 different stations be compared, for the prices charged for feed varied 

 greatly at the different stations. The Wisconsin prices for feeds, 

 for example, were much lower than were charged by the Maine Sta- 

 tion. Many interesting comparisons may be made from the table. 

 At the New York Station the Holstein cows gave the most and cheap- 

 est milk, while the Jerseys and Guernseys gave the richest milk and 

 produced butter fat at the lowest cost for feed consumed. The Short- 

 horn cows at the New Jersey Station produced more milk than the 

 cows of any other breed at any station and at reasonable cost for the 

 feed consumed. The butter fat, however, was less economically pro- 

 duced.
