Minnesota experiments. — At the Minnesota Station, Shaw fed pigs 
of the Tamworth and Yorkshire breeds in comparison with Poland 
China. Like the Iowa 1 rials, this was really a comparison of the 
feeding ability of pigs of the bacon type with those of the Lard type. 
They were fed in pens 8 by L2 feet, with access to yards, lnit with- 
out past ore. The grain fed consisted of shorts, corn meal, and ground 
barley in varying proportions, and in the first experiment skim 
milk was fed. In both experiments green and succulent feed, such as 
pease, <>at>. corn, rape, and roots, was led. I >uring t he first experiment 
one lot of Poland China pigs was on a ration that was mainly of corn 
meal, some shorts being fed in add it ion. The pigs in the fust experi- 
ment were sold at $4 per 100 pounds and those of Hie second at - 
pei- loo pounds, 'fhe following are the results for the purebred lots:
