8 Contained 11.3 per cent of pentosans. 
A comparison of the composition of portions of the honey locust 
with that of corresponding parts of the mesquite bean shows that, 
while the locust pods have a slightly lower total sugar content, the 
entire fruit of the honey locust is materially lower in crude fiber and 
probably averages somewhat higher in crude protein. ^ 
CAROB. 
Table 11 gives the results obtained by Jaffa and Albro (16) on 
the composition of the pods, seeds, and whole fruit of the carob, as 
well as the results on imported Italian, Portuguese, and Cyprus 
carob beans analyzed in the Bureau of Chemistry.
