kafir ; feterita, dwarf milo, and kaoliang. As indicated by its digesti- 
bility, 77.3 per cent, wheat protein is even more completely available 
to the body. Since the sorghums contain less protein than is found 
in either corn or wheat, and as these tests indicate that the protein, 
gram for gram, is less thoroughly digested than that of corn and 
wheat, it may be concluded that both corn and wheat contain more 
available protein than do the sorghum grains. 
DIGESTIBILITY OF THE SORGHUM MEALS PREPARED AS MUSHES. 
DIGESTION EXPERIMENTS WITH KAFIR MUSH. 
To ascertain whether or not the method of cooking the sorghum 
meals influences their digestibility, the series of tests reported in the 
following pages was made. In these experiments kafir meal from 
the same lot as that used in the preceding tests was cooked as a mush 
(p. 5), which was eaten with a basal ration consisting of apple sauce, 
butter, sirup, and sugar. The diet proved entirely satisfactory for 
the tests, in that it was sufficiently appetizing to preclude any psychic 
dislike of the food, so that a nominal quantity of mush was willingly 
eaten. The same subjects cooperated in these tests and continued 
the same routine that was followed in the previous experiments. 
The experimental data of three experiments with kafir mush are 
summarized in the following tables:
