Miscellaneoiis, 227 



Wlien better known the geological character will help much in 

 dej&ning the physical geography of the surface of this province- 

 In Texas the border of the Llano Estacado coincides with that 

 of the Camanche region for a long distance. It is evidently more 

 the retentiveness of the soil than its mineral composition that 

 affects the growth of trees, for all soils contain more or less of their 

 essential ingredients. 



Even the saline substances, which are supposed by some to 

 make deserts of poi tions of the Great Plains, are rather the se- 

 condary effects of the climate ; for if rains were abundant these 

 salts would become diffused, and in their proper proportions enter 

 into the structure of trees and other plants." 



Catalogue of Coleoptera collected by George Barnston^ Esq., of 

 the Hon. Hudsoii^s Bay Company, in the Hudsoii's Bay 

 Territories. 



Dr. Leconte having expressed a wish to examine any Coleop- 

 tera from the Hudson's Bay Company's Territories which could 

 be obtained in Montreal, Mr. G. Barnston most obligingly placed 

 his collection in my hands for transmission to Philadelphia ; and 

 as Dr. Leconte has kindly furnished me with a list of the species, 

 I have drawn up the following catalogue of them for publication 

 in the " Canadian Naturalist." W. s. d'u.
