SETTLEMENTS ON THE DEMERARY, &C. 263 



is the largest part, and six lines in thickness. They are set 

 with short strong prickles on each side, running the whole 

 length of the leaf, and are covered by a smooth green skin. 

 This skin contains a soft bitter pulp, from which exudes a 

 thick juice. The juice when indurated is the aloes. The 

 process of induration is effected either by the sun, or by boil- 

 ing; but the former is much more valuable. 



The silk grass plant, or curretta, as it is called by the na- 

 tives, is smaller than the American aloes, but similar in ap- 

 pearance. The flowers consist of six petals, six stamina, and 

 one pistil. The leaves arise from the root, and form a large 

 cluster. They are much like those of the American aloes, 

 and are about three feet in length. Their internal substance 

 consists of a saponaceous pulp, mixed with fine white strong 

 threads. The threads, when separated from the pulp, are 

 white and glossy, and very much resemble silk; and curious 

 nets and strong ropes are made of them. The pulp is used 

 for washing, instead of soap. 



The siliqua hirsuta, or cow itch, is a plant like the vine, 

 long, slender, and creeping. The leaves are thin, pointed, 

 and covered with a down. The flowers grow in clusters, and 

 are followed by a pod, somewhat similar to the common pea 

 in shape and size, and containing several purple beans. The
