tained. As a feeding material there seems to be only one objec- 
tion to them, and that is, a slight flavor given to milk when the 
beans are fed in excess to the dairy cows. This objection, how- 
ever, could be overcome by feeding the beans after milking, 
rather than before milking. The whole pods of the algaroba 
show the following percentage composition: Water 15.26, pro- 
tein 8.89, fat .58, nitrogen free extract 47.27, crude fibre 24.75, 
ash 3.25. The seeds alone, however, have the following percent- 
age composition: Water 14.38, protein 33.62, fat 3.94, nitrogen 
free extract 36.78, crude fibre 6.84, ash 4.44. It has long been 
known that on account of the hard case, like that of a shark's 
egg, surrounding each seed, the seeds themselves are not digested 
by live stock. On this account, if the pods are fed whole, the 
protein content is largely lost and the pods do not furnish a 
ration so well balanced as would be the case if the seeds were 
rendered digestible. 
Realizing the great importance of algaroba beans as a forage, 
a number of persons made attempts to grind the pods, in order 
to crack the beans, and thus render them available as food. Mr. 
Paul Isenberg spent a great deal of time and money in this ex- 
periment, during which confident promises of success were made 
by mainland millers, without ultimate success. Similarly, Mr. 
F. G. Krauss of this Station, while connected with the Kameha- 
meha Schools, had experiments made by six or more mainland 
concerns who at first believed that some of their mills, designed 
for grinding drugs and miscellaneous materials, would success- 
fully meet the problem of grinding algaroba beans. All their 
tests, however, proved that the machinery then in use was not 
adapted to grinding the algaroba. The difficulty in the way of 
grinding the beans is furnished by the large amount of sugar in 
the pulp of the pods. This sugar is in essentially the condition 
of molasses and gradually accumulates on the milling machinery, 
forming a layer resembling vulcanized rubber in consistency, 
and ultimately causing a heating of the machinery so that it has 
to be stopped. The cleaning of mill machinery which has once
