 Fig. 15.-Relative palatability of the different species of crotalaria was de-
 termined by the order of preference shown by cows when given free access to
 them. Wire racks divided into four compartments each were used.

 Four-compartment racks of woven wire were constructed
 above solid feed troughs, as shown in Figure 15. The artificially
 dried hays were placed in the racks, one species per compart-
 ment, as listed in Table 8.

 A total of 15 cattle in groups of 3 to 8 animals was used in
five consecutive palatability trials of 7 species of crotalaria
as artificially dried hay during the winter of 1931. Dried soy-
bean hay was offered in the eighth compartment.
 The cattle preferred soybean hay to all other in the racks.
C. intermedia, C. incana, and C. lanceolata ranked in palatability in the
order given. C. usaramoensis and C. grantiana were fifth and sixth.
