THE PIGEON PEA '. CULTURE IX HAWAII. 15 
to be fumigated. The compartment described above would there- 
fore require about one-fourth to one-half pound of carbon bisulphid 
per fumigation. The chemical should be placed in a shallow dish 
and set on top of the pile of seed to be fumigated. As the liquid 
volatilizes, the vapor flows over the sides of the container, and being 
heavier than air seeks the lower levels. Fumigation should be con- 
tinued from 24 to 36 hours. Those doing the fumigating should use 
every precaution not to inhale the gas or to bring a light near the 
vapor, which is very inflammable. 
In another publication 4 mention has been made of the opportunity 
for enterprising and suitably equipped farmers to grow standard 
varieties of seed, especially the seed of the pigeon pea, the demand 
for which now greatly exceeds the supply. It is desired to again 
emphasize this fact. The very best seed strains may deteriorate rap- 
idly in careless or inexperienced hands, but the seed business is. or 
should be, a highly specialized undertaking. It is likely that there 
will be an increasing demand for the pigeon pea once its exceptional 
merits become well known. 
PIGEON PEA AS FEED. 
FEEDING VALUE. 
The feeding value of a product depends not alone upon its com- 
position and digestibility, but to a very large extent upon its pala- 
t ability to the animals fed. TThile there have been received some 
reports indicating reluctance on the part of certain animals to con- 
sume pigeon-pea feed, the majority of feeders have found that all 
classes of live stock readily learn to eat it without the admixture of 
other feeds. This seems to be the case especially when live stock 
has access to the growing crop as pasturage. At the Haiku substa- 
tion no animal has yet been found which does not browse freely upon 
the growing plant. At the Haiku ranch, on the island of Maui, the 
dairy herd of 50 cows has been maintained in excellent condition on 
pigeon-pea "tops " constituting the upper third of the plant, which 
is the heavily podded portion. The tips and pods are usually eaten 
first and then the more woody parts, only the thick stems remaining 
uneaten. Work mules will chew up even a large part of the woody 
stem. Poultry will jump as high as 3 feet to get at the pods, and 
they are very fond of the blossoms. Bees apparently gather nectar 
freely from the flowers. It has already been remarked that the 
Molokai ranch has marketed some of its best carcasses of beef direct 
from pigeon-pea pasture. The Haleakalea ranch, on the island of 
Maui, has likewise pastured a 100-acre field of growing pigeon pea,
