maintaining, with xevy satisfactory results, 250 head for a period of

The greatest value of the pigeon pea as a feed seemingly lies in 
its possibilities for replacing a large portion of the imported grains, 
millstuffs, and hay. These are still brought into Hawaii from the 
mainland at great expense and heavy consumption of carrying space 
on the already congested steamship lines.

MILLING AND MIXING FEEDS. 
It is believed that the milling of pigeon peas bids fair to do away 
entirely with imported feeds in the not distant future. The combined 
stems, pods, and seeds cured as hay can be milled into a meal similar 
to the extensively used alfalfa meal ; the ground pods and seeds can be 
used in the same way as corn-and-cob meal ; or the grain alone, either 
whole, cracked, or finely ground, can be mixed with other Hawaiian- 
grown feeds and supplemented with refuse molasses. As a matter 
of fact, the Haiku substation has, during the past four years, grown. 
milled, and fed to half a dozen head of live stock the entire amount 
of feed consumed, fully 25 per cent of which was pigeon-pea product. 
This feed has been fed in comparison with the best imported feeds, 
with a distinct advantage, both in cost and general well being of the 
animals, in favor of the home-grown feeds. A mill has been estab- 
lished at Haiku which grinds and mixes 10 to 25 tons of feed each 
working day of the year. From 10 to 20 per cent of this feed is made 
up of milled products of the pigeon pea. 
In many instances the grinding of feeds has been found unprofit- 
able, but this is not always the case. After careful observations it 
would seem that the extra cost of milling the pigeon-pea plant should, 
in the majority of cases, more than pay for itself in view of the in-
