By comparing this table with the preceding one, it will be 

 seen that the feed units per cow increased materially during the 

 last two years. This was undoubtedly due to the extremely dry 

 summers. 



By comparing this table with the preceding one, it will be 

 herds with the increase of production of Herd B, which was one 

 of the herds in the association, one would naturally infer that 

 some of the other members of the association did not as extens- 

 ively put into practice the lessons taught by the records. And 

 just therein is a lesson, namely, that it does a man little good to 

 have dairy knowledge, unless he puts that knowledge into prac- 

 tical use. Yet, figuring the butter at 22.2 cents, the income per 

 cow lias been increased $17.07 more than it was during the first 

 year the association was operated. 



And these results are not exceptions. In fact all the older 

 associations show a steady increase in yield as well as improve- 

 ment in economic production. 



The following table shows what systematically kept records 

 will accomplish in the line of milk yield. The milk production of 

 1,172 herds on the island of Fyen, Denmark, is found to be as 

 follows : '■''''%
