Besides the kinds of trees already mentioned, 

 we will have occasion, in speaking of underwood, to 

 mention the Hazel, the Hawthorn, the Holly, and 

 several other plants, which partake nearly as much of

 natives, and, of course, very hardy. 



Of the trees now enumerated the lime is propa- 

 gated by layers ; the willows and poplars are propa- 

 gated by cuttings, with the exception of the silver 

 or white species, which is commonly increased by 

 the same means as the lime ; all the rest generally

 firs, the birch, and the oak. The ash, elm, &c. re- 

 quire a richer soil
