Bj this arrangement the feeding-troughs are so supplied that 
each animal gets its daily rations of whey. 
Each patron is allowed the keeping of one hog for every four 
or five cows from which he delivers milk. The proportion of 
hogs varies of course with the supply of whey. Patrons who 
do not care to keep swine at the factory have the privilege of 
carting a certain amount of whey from the factory to the farm, 
and feeding as desired. 
The difficulty of keeping the factory premises free from bad 
odours has induced many factory men to break up the pens 
and banish swine entirely from the establishment. In such 
cases the whey is run into a reservoir a considerable distance 
from the buildings, and patrons, after delivering milk, fill the 
carrying-cans with whey and cart back to the farm. 
In feeding whey to swine, bran, ship-stufTs, or some kind of 
meal, should be mingled with the whey. When this is done a 
good quality of pork is made, and considerable profits are often 
realised from the whey. We do not approve of feeding hogs 
entirely upon whey : it do3S not contain the elements of nutrition 
in the right proportion to preserve the animal in good health and 
make the best quality of pork. 
Hogs, it is true, will live on whey and take on fat, but the pork 
is soft, watery, and of inferior quality. It is doubtful whether 
such pork is a healthy article of food, as swine fed exclusively 
on such watery slop soon show symptoms of disease. Still, 
many dairymen keep a portion of their hogs on whey alone, and 
sell in early fall to the butcher or packer. 
Absorbents, such as muck, sawdust, dry earth, &c., should be
