FORAGE PLANTS. 151 
of whieh are gathered for this purpose, The branches of several 
leguminous shrubs and of Morsay moringa ave much relished by 
rattle, and the plants of the cultivated /haseolus mungo and of peanuts 
form excellent forage. Attempts have been made to cultivate alfalfa 
(Medicago sativa), but this plant evidently flourishes best in dry cli- 
mates where irrigation is practiced. It does not thrive in Guam. The 
‘arest approach to clover on the island is the tiny Jesbomea tri- 
dove, which @rows close to the ground and forms a thick sward in 
places where ‘the grass does not crowd it out. 
Cattle and hogs are very fond of the fruit of Arfocarpus communis. 
After hurricanes, when the ground becomes covered with breadfruit, 
hogs eat great quantities of it and become very fat. The sweet pods 
of Pithecolobium dulce ave also eaten by animals. Prosopis juliflora, 
which is an important forage tree in the Hawaiian Islands, has not yet 
become established in Guam. Cattle and horses feed upon its foliage 
as well as upon its pods, and there is no reason why it should not 
thrive on the island. 
Among: the grasses the most nutritious is Bermuda grass (Capriola 
dactylon), called **grama” by the natives. It grows luxuriantly in 
the sandy soil of the lowlands. Dactyloctenium ucgyptiacum and 
Kleusine indica ave edible, but coarse and not much relished by horses. 
Stalks of green maize and the leaves of ripe maize are excellent for 
food. Many of the coarser grasses growing in damp places which 
horses and cattle will not eat are eaten by buffaloes. Reeds (Zrvehoon 
rorburghi’) ave often collected for fodder, and are especially relished 
by buffaloes. They are rather coarse when old for cattle, but the 
young shoots are eaten by them. 
Among the plants elsewhere reputed to be injurious to animals is 
Leucaena glauca, an introduced shrub, which is very common in the 
Bahama Islands. Mr. L. H. Dewey, of the United States Department 
of Agriculture, while on the island of New Providence was shown 
horses, without manes or tails, which had lost them, it was declared, 
as the effect of cating this plant. 
WEEDS. 
The number of tropical weeds which have found their way to Guam 
is remarkable. In waste places, along the roadsides, on the borders 
of rice fields, and among growing vegetables, nearly all the weeds are 
of species widely spread over the warmer regions of the world. 
Some of them, like the malvaceous Urena and tiliaceous Triumfetta 
have prickly, bur-like fruits with hooked spines; others like the milk- 
weed (Asclepius curassavica) have silky pappus attached to the seed, 
which provides for their dispersal by the wind. There are also com- 
posites (Glossogyne) with retrorsely scabrid bristles attached to their 
achenes, and marsh plants with seeds which readily adhere to the feet
