54 SELECT PLANTS FOR INDUSTRIAL CULTURE 



many parts of the globe. The writer saw it disseminated in the 

 mountains of St. Vincent's Gulf as early as 1847. It is one of the 

 richest of all grasses, grows continuously and spreads readily from 

 seeds, particularly on fertile and somewhat humid soil, and has 

 proved, as a lasting and nutritious fodder-grass or pasture-grass, 

 one of our best acquisitions. Very early out in the season for 

 fodder. The chemical analysis in early spring gave : albumen, 

 2-80 ; gluten, 3-80 ; starch, 3-30 ; gum, 1-70 ; sugar, 2-30 percent. 

 (F. v. Mueller and L. Hummel). 



Broussonetia papyrifera, Ventenat. 



The Paper-Mulberry. Islands of the Pacific Ocean, China, Japan, 

 perhaps only truly indigenous in the last-named country. The bark 

 of this tree or shrub can be converted into very strong paper. It 

 can also be used for textile fabrics ; furthermore, the cloth made 

 from it can be dressed with linseed oil for waterproof coverings. In 

 cultivation the plant is kept like an osier. The leaves cannot be 

 used for silkworms. European fabrics have largely superseded the 

 clothing made of this plant in the South Sea Islands. 



Buchloa dactyloides, Torrey.* 



The true Buffalo grass of Kansas, naturally extending from 

 Canada to Texas, forming a large proportion of the food of the 

 buffaloes on the prairies (Engelmann). Dioecious, creeping, only 

 rising to half a foot or less. It is extremely fattening, but apt to 

 be suppressed by coarser grasses on places where these are not 

 trampled out or kept down by the pasture animals. 



Buddleya Madagascariensis, Lamarck. 



Madagascar. Of the numerous species of Buddleya, the most 

 eligible for shelter-copses on account of its great size and always 

 tidy appearance, as well as vigour and celerity of growth. It is 

 ever-flowering, highly elegant, and tolerant to many kinds of soil. 



Bursera elemifera, J. Hooker. 



Mexico, up to the temperate plateau. This tree furnishes the 

 Mexican Copal or Elemi. 



Butea frondosa, Roxburgh. 



The Dhak or Pulas of India. This magnificent tree extends to the 

 Himalaya mountains, ascending to elevations of 4,000 feet, and 

 bears a few degrees of frost. It is very rich in a peculiar kind of 

 kino, which, according to Muspratt, contains up to 73 per cent, of 

 tannin. The Lac insect is also nourished by this tree.
