which it is in some degree a substitute, though spruce boards 

 do not possess the good qualities 

 of pine in the same degree. It 

 is much used in building. The 

 hemlock, as you are aware, is a 

 majestic tree, though of very 

 little use ; and as it grows on 

 the poorest and most swampy 

 land, it is generally regarded as 

 an incumbrance, not worth the 

 labour of felling. Yet it is some- 

 times sawn into board and plank; 

 the former, though rough-grain-

 latter, from its solidity, is well 

 enough adapted for the flooring 

 of barns. But as many good- 

 looking trees prove unsound at

 and is often burnt on the land 

 when cut down, after having 

 been first stripped of its bark, 

 which is bought at a good price 

 by the tanners. 



C. What is that yellow hair-like substance, which de- 

 pends in long ragged masses from the hemlock and other 

 trees, but most abundantly from the spruce ? 



F. A friend of mine gave it the name of " Absalom's 

 Hair." It is a Lichen, but I do not know its name. It 

 chiefly entwines about the upper branches of the tree, to 

 which I should suppose it is very prejudicial, as those trees 

 which are covered with it seem almost in a dying state. It
