which averaged about 50 pounds in weight. The latter was given for 
ninety- nine days to I Tamwortfa pigs, averaging about 50 pounds in

Effect of cottonseed meal on pregnant sows. — Dinwiddie* fed a 
native SOW carrying her third litter on a ration of cotton-seed meal 1 
part and bran .'5 parts for eighty days before farrowing. She ate a 
total amount of 1 12 pounds of cotton-seed meal, which was L.39 pounds 
daily and 0.8 per cent of the estimated initial body weight. The 
ration agreed with her and there appeared i«> be no harmful effects on 
the fetal liner, it being farrowed safely, with no stillbirths. 
. ct of crucU cotton oU. — Dinwiddie fed •'{ pigs on a rat ion of corn 
meal 1 part, wheal bran 2 parts, and crude cotton oil 0.1 to 0.4 part. 
The amounl of cotton oil fed (estimating the fat content of cotton 
meal at L4 percent) was equivalent to that contained in from 0.25 to 
L8 pounds of cotton-seed meal, the smaller amount having proved 
fatal in the Arkansas results, already discussed. These pigs were on 
the cotton-oil ration one hundred and forty-four days. The amount 
of oil fed for the entire time to each pig was 21 pounds, equivalent to 
L50 pounds of cotton-seed meal. The average daily amount of oil 
consumed varied from 0.06 pound (meal equivalent, 0.4 pound ) to 0.24 
pound (meal equivalent, 1.6 pounds). The average daily amount of 
oil fed for the entire test was 0.14 pound (meal equivalent, l pound). 
r ldie pigs made an average daily gain of 0.6 pound, and suffered no 
serious effects from the oil. 
/ 's, of cotton-set d meal in fh< fi > d lot. —The ase of cotton-seed meal 
in the feed lot must be very carefully guarded, especially until the 
conditions under which it may be used without danger and the cir- 
cumstances which govern the demonstration of its poisonous proper- 
ties are more thoroughly understood. The feeding of the cotton-seed 
meal which the South produces is one of the ureal" st problems of agri-
