and corn in each state are added together, we find that hogs 

 varied 196 points from corn in the forty-eight states; dairy 

 cattle varied 233 points from corn; horses, 401 points; beef cat- 

 tle, 489 points; and sheep, 788 points. 



The average rank of the states in corn, hogs, and sheep 

 for the nine years is herewith presented graphically. It will be 

 noticed that in only four states do sheep rank closer to corn 

 than do hogs. These are New Hampshire, Pennsylvania, 

 Michigan, and Wisconsin. In Rhode Island and North Dakota

 Corn Production. 



These graphs show the average rank of the various states in corn produc- 

 tion from 1907 to 1915, and in numbers of hogs and sheep on January 1, from 

 1908 to 1916 inclusive. Hogs are closely related to corn, followed by dairy 

 cattle, horses, beef cattle, and sheep in the order named. Sheep raising 

 has practically no dependence on corn production. 



sheep and hogs vary an equal number of points from the rank 

 in corn. In each of the remaining forty- two states, hogs rank 

 closer to corn than do sheep. Notice how closely corn and hogs 

 are associated in the first eight states. There seems to be no 

 correlation between sheep and corn.
