*Milked as usual in the morning and again at midday to conform to the time of 
taking other samples. Milking at noon on all days for which samples were analyzed. 
Cotton Seed Hulls .—Hulls from different and even from the same mill 
vary widely in composition owing to the adherence of larger or smaller 
quantities of the finely broken kernels. Such variation may occur in the 
analysis of the same lot from imperfect sampling, or in the same sample 
from imperfect mixing of the different parts of the ground hulls. The 
former source of error was avoided by drawing two ounces of hulls from 
each weighed feed, preserving in air-tight jars till end of experiment, 
then mixing and sampling for analysis. The waste hulls were treated in 
a similar way. All precautions were used by the analyst to secure a uni¬ 
form mixture of ground samples for analysis. 
Solid Excrement .—The total solid excrement was thoroughly mixed at 
the end of each day, sampled, and the sample dried, first in water bath 
and then in hydrogen bath to constant weight, as were the waste hulls 
also. The solid excrement for each day was analyzed separately and the 
percentage composition is shown in Table III, along with that of the 
hulls and meal fed and waste hulls. 
The chemical methods followed were those of the Association of Offi¬ 
cial Agricultural Chemists. 
In Table II we have total weight of waste hulls for each feed, and 
total solid excrement for each day, with the per cent, of water and dry 
matter they contain. These determinations were made in the case of the
