ON WASTE LANDS. 7 



Scotch fir is of a very quick growth 

 for ten years, the oak and beech of a ve- 

 ry flow growth for near that time) to keep 

 them warm and to encourage their growth. 

 The praclice is very wrong, and quite con- 

 trary to the prefent fyftem of thick plant- 

 ing. If the firs are planted at fix feet 

 diftance, with an oak between, they will 

 finother the oaks in a few years ; and if 

 taken away fooner, they do not anfwer 

 the end they were planted for. . If the 

 oaks are planted alone at three feet di- 

 ftance, they will thrive much better, for 

 they fuffer more from the cold when the 

 firs are taken away, than any advantage 

 they can receive from their warmth while 

 they remain. When the firs are taken 

 away your oaks fland at fix feet diftance, 

 which is too much, as the intention of 

 planting thick is fruftrated, which is to 

 prevent pruning and to keep the trees 

 warm, both which are of the greateft com 

 iequence to plantations on poor land.
