 cedar, larch, fpruce fir, filver fir, Scotch fir, and

 put, abele, beech, walnut, fycamore, and birch. 



Thefe after being expofed to the injuries of the

 Larch, the heart found, but 



the fap quite decayed. 

 Spruce Hr, found. 

 Silver fir, in decay. 

 Scotch fir, much decayed. 



Pineafter, quite rotten.

Thefe planks were cut out an inch and a half 

 thick, from trees of thirty years growth.

 ftances muchdifappo.nted my expedation. — How., 

 ever, thus I found them; and as every experiment 

 of this kind may be fo ealily conducted b) any 

 body, I hope it will be again and again made, upon 

 an enlarged plan, with additional trees of different 

 ages, abroad, and under cover; whereby the moft 

 profitable application of them may be fully af. 

 certajned. 1 am, your obedient fervant,
