[For the information of readers who may not be able to 

 follow the above technical description, we may state that the 

 insects referred to are those earwig like forms which are found 

 underneath a white web covering the interstices in the bark of 

 the trunks of large trees. — P.C.] 



SOME ECONOMIC PLANTS AND THEIR PLANTING 

 PROSPECTS. 



By E. D. Ewex. 



There are a very great number of economic and valuable 

 plants which here, are chiefly conspicuous by their absence ; and 

 some others which might as well be absent for all the notice they 

 attract and all are exceedingly interesting from the fact that 

 there is perhaps no place in the whole world comparable with 

 this colony in its capacity for growing successfully various economic 

 plants native to the most diverse tropical and sub-tropical 

 countries and climates. 



For instance there are not many other places where one can 

 see growing and fruiting freely in the open air within a feAv yards 

 of one another the Coca from the Andes, the Loquat from Japan, 

 the Oil Palm from West Africa, and the Mangosteen (which 

 won't fruit in India) from Malaya, not to mention others from 

 Australia, Chili and South Africa. 



One of these former which from its evident adaptability 

 and its valuable product, highly merits at the present juncture 

 introduction and trial, is the Guarana, N.O. Sapindaceae, of 

 which there are (at least) two species, viz. : Paullinia Sorbilis (?) 

 and P. Cupand, (H.B., and K).
