much greater. The hay cost $8.24 per ton, and 
the oat-and-pea feed, $22.60, and the oat-and-pea 
straw, $6 per ton. The use of five pounds of the 
straw and seven pounds of the oat-and-pea feed 
resulted in 2.6 per cent larger yield of milk than 
fourteen pounds of the hay, although the feed cost 
of milk per hundred was 61.6 cents, when the oat- 
and-pea ration was fed, and 49.9 cents when 
the oat-and-pea hay ration was fed. The experi- 
ment showed clearly that both rations are palatable 
and digestible, and can be successfully used as 
partial substitutes for purchased feeds, although 
indicating the greater economy as a source of 
nutrients of the oat-and-pea hay. Allowing the 
crop to ripen, therefore, is not a profitable prac- 
tice, excepting when labor is abundant and cheap, 
or when it is more desirable to produce fine feeds 
than to purchase them.
