THE HOG [NDUSTRY.

Dinwiddie points out particularly thai a corn-meal and cotton-seed- 
meal ration, which one would naturally selecl as giving the proper 
proportions between nitrogenous and carbohydrate constituents, 
proved the most fatal in his experiments, and that tin* bran and cot- 
ton-seed meal ration, the most nitrogenous of the three, required the 
most time for the dangerous property to asserl itself. Contrary to 
what one would expect from the Oklahoma results, roots did not have 
so good an effect as the wheat bran. 
The pigs received from 0.64 to 0.8 pound of cotton seed per head 
daily, which was from 1.5 to 1.6 per cent of their initial body weight. 
The first death occurred in the case of the pigs on corn and cotton- 
seed meal thirty-five days after the feeding commenced, an average 
of 23 pounds cotton-seed meal being eaten per head. In the case of 
the pigs fed corn, cotton-seed meal, and roots, the first death was 
forty days after the beginning, an average per head of 25 pounds of 
cotton-seed meal being eaten. The first death in the case of the pigs 
on bran and cotton-seed meal occurred sixty-one days after the begin- 
ning, 45 pounds of cotton-seed meal being eaten per head. Up to the 
time of death the gains of the pigs on cotton-seed meal were as good 
or better than those of the pigs on corn chops and bran (Lot IV). 
Following the experiment in which all the pigs on cotton-seed meal 
died, Dinwiddie a fed 4 native pigs, averaging about 50 pounds in 
weight, on various rations, cotton-seed meal being a prominent factor, 
constituting one-fourth of the ration. Turnips were fed for eighty 
days, after winch rye, oats, and alfalfa were given for two months. 
The pigs were fed from Februaty 26 to November 6, 1902. Onlj 7 1 
received cotton-seed meal throughout the experiment, and for a small 
part of the time none was given to it. The other pigs received rations 
of equal parts of bran and corn meal or ear corn after being taken 
from the cotton-seed-meal ration. 
Dinwiddie presents the following tabulation of the results of this
