Clean Milk 



carried, and this exposure and the exposure 

 to manure in the stalls is a source of the so- 

 called " animal odor," supposed by dairy 

 farmers to be a characteristic of fresh milk. 



A soft and muddy surface should be 

 drained, the pools filled in, and a new surface 

 made with firm, hard material, such as a man 

 uses to make the paths around his house. 

 Some material is usually available, and at 

 moderate cost — crushed stone, gravel, sand, 

 or the ashes from the furnace or the stove. 

 Some farmers cover the yard with a mate- 

 rial which, being useful as a fertilizer, can 

 be gathered up with the manure, when the 

 cow yard is cleaned. 



The evils of a bad cow yard will sometimes 

 be reproduced in a pasture lot. Constant 

 use has destroyed the turf, and the surface 

 becomes so trampled and cut up that the field 

 is little better than a muddy yard, resulting 

 in a defilement of the cows, which could be 

 avoided by changing the pasture frequently.
