Prosopis juliflora, the algaroba tree, or kiawe, as it is known, is one 

 of the most valuable sources of feed in Hawaii. It is one of the 

 mesquite trees. It was introduced into Hawaii in 1828, covers exten- 

 sive areas, and will eventually cover all the lower elevations not 

 devoted to cultivated crops. The algaroba is admirably suited to dry 

 regions. It is found in large tracts on the leeward sides of the 

 islands. Although found at greater elevations, it occurs mostly below 

 1,000 feet, probably because of its preference for dry localities. The 

 tree is a source of a large part of the honey produced in the island. 

 The wood is very valuable for fuel. The ranchers most dependent 

 upon the algaroba find it to their interests to carry on a honey busi- 

 ness in connection with their other work, but it is here considered 

 merely as a feed for stock. The pods contain a number of seeds, 

 encased in a hard seed coat, and surrounded by a sugary, gummy 

 substance. The analysis of the entire pod is given by Shorey 1 as: 

 Water, 15.26 per cent; protein, 8.89; fat, 0.58; nitrogen-free extract, 

 47.27; crude fiber, 24.75; and ash, 3.25 per cent. The beans of the 

 algaroba, being protected by a hard seed coat, escape mastication 

 and digestion and pass through the alimentary tract entire. This 

 fact accounts largely for the rapid and widespread distribution of 

 this species in the islands. Domestic animals have been the greatest 

 factor in scattering the seed. 



For several years experiments in milling the pods proved of no 

 avail. The sugary pulp gradually accumulated upon the crushers or
