Now as the twelve trees above, contained 213 cubic 
feet 300 inches of timber in fpring 1743, and have 
increafed to 322 cubic feet 333 inches in autumn 
1758 ; that is, 109 cubic feet 33 inches in 16 years 
growth ; if all the trees were of the fame kind, 109 
feet pays 3 per cent, for Handing : and the fix oaks 
pay near the fame intereft, although one of them, 
N° 2. appeared paid thriving in 1743 s for the in- 
creafe of the fix oaks is from 112 feet 1 quarter 17 r 
inches of timber, to 167 feet 138 inches, i. e. 54 
feet 2 quarters 399 inches; which is above 3 per 
cent. But if you take only the five thriving oaks, 
then their content is, from 57 feet 3 quarters 267 
inches, to 103 feet 2 quarters 58 inches ; i. e. 45- feet 
2 quarters 223 inches of timber; or near y per cent » 
And the increafe of the moft thriving oak, N° 8. 
appears, by the above table, to pay above 12 { per 
cent, and the Scotch fir, N° 9. being under 2 feet 
and half of timber in fpring 1743, and 10 feet in 
autumn 1758, pays above 18 per cent. Befides it 
fhould be confidered, altho’ I meafured the largeft 
and moll thriving oak and Scotch fir in 1743, yet 
feveral others of the fame age, both oaks and Scotch 
firs, have greatly exceeded the meafured trees for 
many years pafi; e. g. the oak N° 11. appears by 
the table two feet 8 inches 2-8ths in circumference; 
and another juli by it is 2 feet 1 1 inches 6-8ths; and 
an oak tranfplanted from this grove, is 3 feet 9 inches 
5-8ths round ; yet this laft tree was confiderably lefs 
than the firft when removed, and not planted in a 
better foil, and yet is 1 foot 1 inch 3- 8ths larger than 
the original tree. The firft contains 4 feet 1 quarter 
336 incites, and has gained 2 feet 3 quarters 220 
inches-
