Tliere are niimerons varieties or oil palms along the West African coast ex- 

 tending sometimes for a distance of 100 or 125 kilometers. In 1909 the palm 

 trees in West Africa produced more than 100,000 tons of oil and 250,000 tons 

 of palm kernels, and yet this is only a part, perhaps a third, of the amount 

 that Africans could supply, allowing about another third, which is required 

 by the natives for food. (Adapted from The Monthly Bulletin of Agricultural 

 InWlligence-and Plant Diseases, vol. 2, p. 314-)

"A handsome Chinese tree known as 'Tsao-k'o shu,' abundant throughout 

 the Yangtze Valley up to 3,500 feet altitude. It gi'ows 60 to 100 feet tall and has 

 a thick trunk, smooth gray bark, a spreading head with massive branches, 

 small pinnate leaves, and inconspicuous greenish flowers. The latter are fol- 

 lowed by pods or 'beans, ' which, when ripe, are black, 6 to 14 inches long and 

 three-fourths of an inch to 1^ inches wide. These pods are broken up and are 

 in general use for ordinary laundry work, producing a good lather in either hot 

 or cold water. They are also used in the process of tanning hides. The sapon- 

 aceous fat is contained in the pod itself, which is the only part utilized, the hard, 

 flattened brown seeds being discarded." (Wilson, A Xaturalist in Western 

 China, vol. 2, p. 71.)
