een swine to a farm, and in Iowa thirty-five. In 

 New York the average is less than two to a farm. 

 It is interesting to note that swine are least numerous 

 in the leading dairy sections, especially the market 

 milk regions. 



It is evident that in New York hogs are kept pri- 

 marily to provide pork for the home larder. Their 

 nearest competitor as a scavenger has long been 

 poultry. Up to the census of 1910, the actual in- 

 tensity of swine-raising was greater than that of 

 poultry. About that year, the number of poultry 

 became equal to or slightly larger than that of swine. 

 The intensity was then approximately one-half ani- 

 mal unit to a farm. With the average number of 

 swine at two to a farm, the average number of ani- 

 mals one year old or over is only about one. There 

 is much less than one brood sow to a farm and conse- 

 quently the litter of each sow is likely to be a distribu- 

 tion among several farms. 



The region of largest swine-production is along 

 the south shore of the Great Lakes and eastward 

 through the Mohawk Valley. There seems to be no 

 reason to expect any large increase in the number of 

 swine. They are urged by some fanciers for produc- 

 tion on green forage and pasture. But other animals, 

 such as the dairy cow, can use this material more 

 efficiently. Warren has shown by calculations from 

 the relative price of crops and of pork that there is 

 an effective price tariff in favor of hog-production in 

 the corn-growing states amounting to one-third to 

 one-fourth of the market value of the animal.
