THE ALDER. 



Although the alder is found in high perfec- 

 tion, in moift foils, and even in (landing water, 

 yet it will grow freely in light, elevated lands, 

 where, however, its tendency is to impoverifh the 

 foil, being only fatisfied with a fupenabundance of 

 moifture. In calcareous and chalky foils it fpeedi- 

 ly languifhes. The alder is naturally found grow- 

 ing by the fides of the mod rapid rivers and 



ftreams ; 



* The nomenclature of soils, we may remark, is extreme- 

 ly uncertain. We have employed the most popular and 

 obvious phraseology, without attempting any new or more 

 correct language.
