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.
