Planted very generally ; does well on roadsides 

 and on ground too indiscriminately cleared — 

 which few native species will.* 



* Tithecolohium Saman, the Rain-tree, a native of the West Indies, Central 

 America, Yenezuela and Guiana, though yielding a timber useless except as firewood 

 is nevertheless a valuable tree. It is a fast-growing and easily-raised species and, if 

 planted along with more valuable kinds, forms an effective nurse for these during 

 the earlier years of their growth. It also yields a valuable crop of sweet pulpy pods 

 greedily eaten by cattle. It is said, moreover, to improve the quality of land encrust- 

 ed with reh inflorescence. The following girth measurements of 13 trees in the 

 Botanic Garden, Calcutta, will give some idea of the rate at which the species grows. 

 The measurements in every case are taken at 60 inches from the surface of the soil 

 — the trees measured were not selected (except No. 13 which was added as being the 

 largest in the whole line) but were contiguous trees 

 College avenue. The trees all date from 1876 ; the 

 January 1890.
