The latter is one of the several plants called "Jeve." Coumautilis, another "Cow tree," native of North Brazil near Manos, yields a milky fluid used for waterproofing purposes. A similar use, according to Spruce, is made of the milk of atree called " Cumai," frequent on the Rio Negro and Uaupes. Lecture II.--Delivered April 25, iSgS. African Rubber. The development of the rubber industry in the equatorial parts of Africa is one of the most remarkable incidents in recent years. As regards the world's commerce in rubber Africa now occupies the second place. Up to within a very late period all the plants yielding African rubber belonged to the single genus Landolphia, containing a group of woody climbers with sweet-scented flowers and edible pulpy fruits. In 1894 a valuable rubbertree, a Kickxia, was discovered in the colony of Lagos, and afterwards found to extend along the whole of the littoral of West Africa from Sierra Leone to the Gaboon.
