1 10 On the comparative value 



for the express purpose of communicating solidity and 

 durability to the sap wood,* and it has also been found 

 in this country, that hickory, when cut and barked 

 with the sap in full flow, becomes very useful and last- 

 ing for the inside work of barns, and is never injured 

 by worms, although generally more subject to their 

 depredations than most other timber ;f and it appears 

 equally probable, that if hemlock is barked standing, 

 the sap will sink into the open pores of the sap-wood 

 of the tree, and communicate solidity to those parts, 

 by condensing within them, instead of spending its 

 powers in increasing the size of the tree, which it wotild 

 have done, if the tree had not been stripped of its bark ; 

 this measure, it is likely, will increase the value of 

 this kind of timber considerably, and bring it into bet- 

 ter repute, and much greater demand in our sea port 

 towns, where it is already used for many purposes, 

 and together with the bark, (now much used, and in 

 considerable demand for tanning,) may eventually raise 

 the value of this tree equal to almost any other timber. 



The youth of this country are remarkably active, 

 and accustomed to the woods, and are better qualified 

 to bark trees while standing, than most other people. 

 The bark of this tree strips much easier than any other 

 timber that is barked, and will admit the operation in 

 the summer, as well as in the spring. 



The value of white pine lumber is too well known 

 to require explanation, and is readily cut and trans-
