THE BABCOCK TEST. 



The Babcock test provides a quick and accurate method of showing 

 the richness of milk, which means its percentage of fat. Next month

 dairy community, in fact in every farm community. Aside from its

 shall send the complete outfit for making the Babcock test to the first 

 ten rural school teachers in ten diiTerent counties making application 

 for it. Here is an opportunity for the rural school teacher to make his 

 work felt in his community. If some of the older pupils are able to 

 handle this test and give a demonstration of it at some of the school 

 meetings or farmers' meetings, it may be the means of interesting farm-

 present Leaflet is ^ent out to all teachers on our lists the same day. 

 We shall consider the first application from each of ten dififerent counties. 



Some teachers in rural communities have already provided them-
