rink without wasting or soiling.

July 26th the hens and chickens were each separated into two lots of
five each, as follows:

Hens, nitrogenous ration, weighed 23 lb. 8.5 oz.
Hens, carbonaceous ration, weighed 23 lb. 9 oz.
Chickens, nitrogenous ration, weighed 8 lb. 15 oz.
Chickens, carbonaceous ration, weighed 9 lb. 1 oz.

The four lots were placed in separate pens where they remained during
the entire experiment, which lasted 125 days. They were fed and
watered once daily, and an account kept of the food eaten and water
drank. At each feeding the food and water remaining were weighed back
and deducted from the amount charged at the previous feeding.

The hens and chickens fed a nitrogenous ration were given daily all
they would eat of the following mixture: 1/3 part wheat bran, 1/3 part
wheat shorts, 1/3 part cotton seed meal, 2 parts skimmed milk, and
will be designated Lot I.

The hens and chickens fed a carbonaceous ration were given daily all
they would eat of a ration of cracked maize and maize dough, and will
be designated Lot II.

Both groups were given a small amount of green clover as long as it
lasted, and afterward cabbage.

For convenience the experiment was divided into five periods of twenty
five days.

FOOD CONSUMED AND INCREASE IN LIVE WEIGHT.

During the first period all the fowls seemed in good health except the
carbonaceous fed chickens; they, during this as in all succeeding
periods, were restless and peevish, always moping or hunting for
something to eat, though their trough was filled. When fed they would
greedily take a few mouthfuls and then, with their hunger still
unappeased, would leave the dish. They always ate ravenously the green
food which was given them, as did the hens and chickens of Lot I. The
hens of Lot II., on the contrary, seemed quite willing to squat about
the pen and subsist on the maize diet, and strangely enough cared
little for green food. The clear maize diet was accompanied by such
ill effects that the chickens of each lot, after the first period,
were given daily each one-fourth ounce of wheat, and the hens each one
ounce. The wheat was increased during the fourth and fifth periods in
the case of the chickens to one ounce each. During the second period
one of the chickens fed nitrogenous food, and during the third period
another of the same lot were taken ill and removed from the
experiment. Both seemed to be suffering from impacted
