a The results In New Hampshire and t he seoond line of Utah results show estimated digestible 
dry matter. 
These figures show what can be regarded as representative values 
of these three methods of feeding, and emphatically demonstrate the 
economy of the grain-and-milk combination. Linfield calls attention 
to the fact thai none of the pigs fed milk alone attained a weight of 
o\ er loo pounds, whereas some of those in the other columns reached 
nearly 300 pounds. It does not always mean profitable feeding for a 
hog to require a small amount of feed to make a certain gain. 
VoLva of miCk at cm-ions prices for (/rain. — Using as a basis the 
results obtained in the investigations already mentioned, Linfield 
makes the following estimates of the value of skim milk as a supple- 
mentary feed in a ration at various prices for grain:

al the Hatch Slat ion. except that the figures do not include the results 
Of feeding (.a milk alone. The averages of their experiments are 
given in the following table. "Starchy feeds' 1 refer to such substi-
