FARM DAIRYING 



udder, from it are taken substances to build up 

 thousands and thousands of tiny cells stored with 

 materials which afterwards form the greater por- 

 tion of the solid constituents of the milk. All day 

 long these cells keep developing, and the udder 

 grows larger and larger. The blood is charged 

 with an extra supply of water. 



The cow has now the materials in readiness to 

 make the finished product, milk. We have pro- 

 vided her with food and water. With these she 

 has carried on the manufacturing process to a 

 certain point, but she needs some outward assist- 

 ance to finish the work thoroughly. She gets this 

 assistance from the calf, when it presses the teat in 

 its mouth, or from us when we likewise squeeze 

 it in our hands. 



We place our hands on the teats thinking we 

 do so in order merely to draw the milk, but we 

 do much more than that. We are co-workers 

 with the cow in helping her to make the milk, and 

 the better we understand our part of the business

The materials for the milk are stored .in the 

 cells of the udder and in the blood. Its final secre-

 hence the great importance of the nervous con- 

 stitution. If a cow were giving ten quarts of
