There is a very marked relation between the number of cows per 
crop acre and the distribution of crop acreage. The farms which 
kept fewer cows than the typical farm of the same size grew little or 
no silage, while the farms that had more cows than the usual farm of 
about the same size grew considerable silage. In most cases, too, the 
farms that had more than the usual number of cows grew more than 
the usual proportion of alfalfa hay. This shows that these two 
crops — corn for silage and alfalfa hay — which produce more than the 
usual quantity of nutrients per acre, are the means used by Chester 
County dairymen to increase the number of cows that their farms 
can carry. 
LIVESTOCK ENTERPRISES 
The farms in this region show only minor differences in the crop- 
ping systems, but there are wide differences in the kinds of livestock 
kept on different farms. In fact it is only on the basis of this differ- 
ence in livestock enterprises that it is possible to make any separation 
of the farms into different groups, because they are nearly ail essen- 
tially of the same type as far as the crops go.
