derived from the resin of the pines, stand only second in 

 value to the wood, as useful products. 



"From the great amount of resin conta'ned in the wood 

 of the pine, the wood is very combustible, and remarkable 

 for its durability/ In the wood of most pines the resin 

 does not seem to be deposited during the life of that part. 

 Old trunks are often found consisting almost entirely~of 

 heart wood, soft, and of a reddish colour, almost free 

 from resin throughout. Where a branch is broken off, 

 the remaining portion becomes charged with resin, forming 

 what is called a pitcJi knot, extending sometimes to the 

 heart. The same thing takes place through the whole 

 heart of the tree, when full of juices its life is suddenly 

 destroyed. It is commonly supposed that the heart-wood 

 of a trunk of Pitch pine, increases in weight after it has 

 fallen to the ground." Emerson. 



Turpentine spirits is the product of distillation of the 

 crude turpentine, over a gentle tire. 



Pilch is produced by burning, in a copper vessel, the 

 residuum of the turpentine. 



Tar is produced by half burning it in a covered vessel. 



Lamp-black is made by burning the above refuse in a 

 furnace leading to a chamber, in which the "soot" is de- 

 posited as a powder, from whence it is collected. 



Venetian Turpentine is made from the European Larch. 



Linnaeus states, "that the Laplanders, for want of 

 cereals, use the inner layer of the bark of the Scotch pine, 

 to make into cakes, which are very palatable." 



Finally, Amber and Petroleum oil, are but the products 

 of the fossil pines of the Carbonilerous Age. 



"The soil natural to pines is that formed originally by 

 the crumbling, or disintegration, of the granitic rocks. 



These, m the forms of gneiss, mica slate and granite, 

 are the prevailing rock of Massachusetts, large portions
