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 nqt 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 :
