RED-WOOD PINE.

est in the places where the trees have fewest sap- 

 wood layers, and where the timber has been planted, 

 that is, where the cones have been kiln-dried — is wor- 

 thy of notice. Scots red pine has generally from 

 15 to 40 layers, Memel from 40 to 50, Canadian of- 

 ten 100. We consider the long moist open winter 

 and cold ungenial spring in Scotland, and the till 

 bottoms soaking with water, perhaps aided by the 

 transplanting, and the kiln-drying of the cones, to be 

 the cause of this early loss of vitality or change of 

 sap-wood into matured. In Poland and Prussia, the 

 earth does not remain so long cold and moist as in 

 Scotland, but is either frozen or sufficiently warm 

 and dry ; — this occurs even to a greater degree in 

 Canada *, and neither the Memel nor Canadian have 

 any chance of being planted or kiln-dried. 



White Larch — Lar'ix communis, {L. pyramidalis). 



White Larch is a timber tree combining so many 

 advantages, its properties so imperfectly known, of 



* The Canadian red pine resembles P. sylvestris or Norway 

 pine so much, that it is usually styled Norway pine by the settlers : 

 Though different, it is so nearly allied to P. sylvestris, that we 

 consider the number of sap-growths may be referred to the climate 

 and soil, and not to the kind, — that is, that, were it grown in Bri- 

 tain, if it did not at first, it would in the course of time come to 

 have fewer sap -growths.
