supplements, that a nutritive ratio of 1 :5.5 is more satisfactory 

 than narrower ones. 



In comparing dry lot and pasture feeding, the latter has given 

 decisively favorable results. The following table shows the lots 

 in the third experiment, according to total gains. Lots 4 and 10 

 are omitted, as their results were unquestionably misleading, ow- 

 ing to unthrifty individuals.

PORK PER ACRE OF GRASS. 



"By comparing the lots fed similar rations in dry yards and 

 on grass, we can obtain a very close estimate of the amount of gain 

 by the pigs which is directly credited to the grass. Lot 2 on pas- 

 ture ate 5,143 pounds of corn and shorts, of which 511.8 pounds 

 would have produced 100 pounds gain if fed to lot 7, making a total 

 of 1,004.9 pounds gain. Lot 2 gained 1,254.7 pounds, or 249.8 

 pounds more than the corn and shorts alone would have produced. 

 In like manner the grass of the other lots accounts for 221.9 pounds 

 gain for lot 2, 0.9 pounds for lot 4, and 207.4 pounds for lot 5. Lots 

 4 and 10 were manifestly lower in thrift as compared with the 

 other lots, so it is probable that 0.9 pounds gain is too low for the 

 grass of lot 4 and 207.4 pounds is too high for the grass of lot 5. 

 Combining the feed and gains, respectively, of lots 4 and 5 and of
