356 H, P. Armsby—Digestion Experiments. 
experiments on fodders grown in foreign countries, no deter- 
minations of the digestibility of any of our fodders having been 
reported. The following determinations of the digestibility of 
clover hay, malt-sprouts and cotton-seed meal by sheep are 
therefore presented as a contribution to our knowledge of the 
digestibility of American fodders : 
ers.—The hay was first-crop red clover hay, of gi 
quality, and nearly free from admixture of other vegetation. 
The malt-sprouts and cotton-seed meal were also of excellent 
quality, as was evident from their appearance and was con- 
firmed by the results of chemical analysis. 
Conduct of experiments.—T' wo grade Cotswold wethers, about 
three years old and weighing about 87 pounds each, were use 
for the experiments. The animals stood in stanchions, each 10 
a separate stall specially built for the purpose. They were fed 
and which were surmounted by a funnel-shaped structure of 
boards, which effectually prevented any scattering of the fodder. 
Each day’s fodder was weighed out separately for from six 10 
ten days in advance, the hay in cloth bags, the bye-fodder 1 
glass fruit jars, and samples were taken at the same time for the 
determination of moisture or for complete analysis. The dun 
was collected in rubber-lined cloth bags (Kothbeutel), attach 
to the hind quarters of the animals by meansof a light harness. 
The bags were emptied every twenty-four hours and the dung 
weighed. 
A sample of about 100 grams of the fresh dung of each 
animal was at once taken and dried in a water bath. When 
an analysis sample in such proportions that the quantity os ries 
s is well known, it is necessary in digestion trials to precede 
the actual experiment by a preliminary feeding in order 
trial each lasted six days, in most cases. Throughout the 
experiments two grams of air-dry salt per day and head were 
given.
