Plantations of Spruce and Silver Firs, intended 

 for large ufeful timber, mould be kept much in 

 the manner above ftated, both in their infancy 

 and middle age. As already remarked, planting 

 and keeping them as thick as is confident with 

 their health, is the befl means of producing tall, 

 ftraight, clean items, and valuable timber. When 

 planted for fcreens or for ornament, they require 

 a different treatment ; which will be noticed in the 

 proper place. 



To Larch plantations, the above obfervations 

 will alfo apply ; and indeed they are applicable to 

 plantations of all kinds of refmous trees. 



It may be proper here to remark, that the ex- 

 posed margins of all young plantations fliould be 

 kept thicker than the interior. The extent to 

 which this rule mould be carried, mud be regu- 

 lated according to the degree of expofure of the 

 fituation, the age of the plants, the tendernefs of 

 the kinds, and other circumftances. 



The manner of thinning neglected older plan- 

 tations will be treated of in September ; the fall 

 of the leaf being deemed the fitteil time at which
