Bamboo. 
In Porto Rico the bamboo is apparently of rather recent introduction, and is 
neither so common nor so widely distributed as night be expected. A single spe- 
cies is growing at numerous points along the military road, but was nowhere seen 
in large quantities, and seems not to be known about Guayama. Neither is the 
bamboo much in use for domestic purposes, although the moist climate is very 
suitable for growing it and the difficulty of securing wood in some localities should 
make its value very considerable for miscellaneous farm purposes. It seems most 
desirable that a selection of the larger and more useful species be introduced from 
Japan, China, and the East Indies.
