KINDS OF TREES, 



In Switzerland, the Silver-fir grows naturally 

 to a wonderful fize, and is efteemed among the 

 moft valuable of their trees. From it is extracted 

 turpentine, of a quality fuperior to that extracted 

 from the larch. 



AMERICAN SPRUCE FIR. 



(Pinus nigra c alba.} 



The Black and the White American Spruce have 

 hitherto been ufed merely as ornamental trees. 

 The white is much more vigorous in its growth 

 than either the black or the red ; and is eafily 

 diftinguifhed from either of thefe by its vigour, 

 and lighter appearance. The black aflumes a 

 deeper green colour than the preceding, and is 

 lefs luxriant in its growth. The red more nearly 

 refembles the black, only the foliage is finer, and 

 the branches more (lender. They have all hither- 

 to been ufed in the fhrubbery and on the borders 

 of finely ornamental plantations, where they may 

 be always in view ; and they never fail to pleafe 

 in fuch flations. They are beautifully ornament- 

 al, as fmgle trees of low ftature, in flickered fpots, 

 in the park or the lawn. 



Whether thefe will ever arrive at the fize of 

 (lately timber trees in this country, time only can 



determine*
