secured by cracking the inclosed nut after the pulp has been removed. The fruit 
is egg-shaped, and from 1 to 1} inches (25 to 37 millimeters) in length. The 
deep red skin is thin, like that of the date. The oily pulp underneath is inter- 
spersed with tough fibers, but has a pleasant taste, and is frequently eaten after 
being slightly roasted. The oil is obtained in quantities by beating the nuts in 
wooden mortars and then skimming off from boiling water, also by less desir- 
able methods in which the nuts are rotted. This is said to increase the yield of oil, 
but gives it a rancid taste unpleasant to the civilized palate, but not injuring the 
oil for export. In Europe the kernels are used for the extraction, under pressure, 
of another oil quite similar to that of the cocoannt and used for like purposes.
