 species. 



It would be tedious to discuss the different 

 kinds of coniferous trees, seedlings of which are 

 offered in the nurserymen's catalogues. Some 

 of them, like Weymouth pine, have been known 

 for many years, and others are of more recent 

 introduction. A planter to whom financial con- 

 siderations are of importance should confine 

 himself to those trees which experience shows 

 grow well in England, and produce timber 

 attractive to timber merchants. Other trees 

 should be left for the plantations of rich men 

 who are patriotic enough to make experiments 

 for the benefit of posterity.
