Another species (Prosopis glandulosa), known also as the Texas 
mesquite, is found alongside of the algaroba in Texas, and there 
are a few trees of this species on Molokai. Seeds from these 
trees have also been planted in other localities. If we accept as 
true the statement that the original seeds were brought from 
Paris by Father Bachelot on his first trip to the Islands, it is 
impossible to determine their exact origin. The tree is, of 
course, not native in France and the seeds must have been 
brought there from some other locality. 
The distribution of algaroba in Hawaii is largely determined 
by the rainfall conditions. The tree thrives best in dry localities, 
and is somewhat sensitive to salt air. Nevertheless, on the wind- 
ward side of Lanai there is a fine belt of algaroba which extends 
to within a few hundred feet of the seashore. The trees which 
grow nearest the water on the leeward side of the Islands, some- 
times have the leaves destroyed by salt spray during Kona 
storms, but recover later, showing little effects from the salt 
water. Algaroba thrives best at low altitudes, but is everywhere 
gradually extending to higher levels, and it is found in some 
localities at altitudes as high as two thousand feet. Apparently, 
it is gradually becoming acclimated to the higher altitudes, but 
it bears most abundantly at lower levels. Considerable attention 
has been given to the distribution of this tree in carrying it from 
one island or locality to another, but, on the whole, its distribu- 
tion has been largely accomplished by stock. Practically all of 
the islands have enormous belts of algaroba forest, extending 
from the sea-shore, on the leeward side, up to an altitude of S00 
or 1,000 feet. 
USES OF ALGAROBA. 
There are few trees which are distinctly useful for more pur- 
poses than is true for the algaroba. Its flowers furnish the most 
important source of pure honey known in the Territory. The 
bee-raisers of the Territory have shown an active interest in 
securing the rights of placing apiaries so as to utilize to the full-
