devoted to trurk and potato crops, showing the importance of these 

 as money crops and the tendency toward more intensive farming. 

 The largest percentage of green manure crops are found on farms 

 specializing in potatoes. The practice is usually to sow rye in the 

 fall and turn it under during the latter part of May or early in June 

 for a late crop of potatoes, which is usually planted during the 

 first two weeks in July. Turning under the rye and keeping the 

 groimd in good tilth and well packed with a plank drag or roller 

 serves to retain moisture, to store humus, and to make general soil 

 conditions favorable for the potato crop.

DISTRIBUTION OF ANIMALS. 



Table XV shows the distribution of different classes of animals on 

 the different types of farms. On the intensive types, dairy cows, 

 poultry, and swine are comparatively more important, while on the 

 more extensive types, stock cattle, horses, and sheep are relatively 

 more important. On the more intensive types of farms growing 

 potatoes and truck, there is relatively a large amount of unmarket- 

 able products which, without stock to utilize them, would be wasted. 

 Dairy cows, swine, and poultry utilize these as well as the permanent 

 pasture, and thus are profitable when in proper proportion to other 

 enterprises.

a An animal unit is the equivalent of a cow, horse, or mule. Four calves, 2 yearlings, 5 hogs, 7 sheep, or 

 100 head of poultry are assumed to be approximately equivalent to an animal linit. The assumption is that 

 each of these equivalents consum<^s about the same amount of feed and produces about the same amount of 

 manure measured in terms of fertilizer value.
