fize, and great beauty ; one that has been meafured 

 repeatedly was, at Midfummer 1769, fix feet two 

 inches and a half in circumference, at fiv-e feet 

 from the ground*, and at Midfummer lafl, wa^ 

 eight feet, fcven inches and a half^ viz, it increafed 

 twenty-nine inches in twenty-one years, being above 

 one inch and one third yearly. The fhafc of this 

 tree is about forty feet long, as ftraight as an ar- 

 row, it breaks all round into fmall branches, and 

 contains between two and three tons of timber. 



nefs of the bar'k iri the latter, but^ daims no dedutSlion for the fmooth 

 bark of the former ; another confidei-ation for the planter is, that elm 

 requires a foil worth ios. per acre, whilft the beech will grow in 

 i^hite land, fearce worth 7s. per acre. 



* That is, five feet on the lower fide, or four feet on the upper. 

 Query, What will be the contents of this tree at 24 years end, af- 

 ter the fame rate of growth ?— A Iha^ tapering regularly from a 

 circumference of 8 feet 8 inches at its bafe, to four feet at itsfummit, 

 will girt 1 9 inches in the middle j for the girt at top 1 2 inches,added to 

 the girt at bottom i6 inches, are equal to 38, which divided by 2, 

 are equal to 19 inches the girt rnidway ; and 40 feet by 19 girt, are 

 equal to 100 feet of timber, its prefent fuppofed content. Then at 

 24 years end, uilowin^ an inch only in a year for the extenfion of 

 the (haft in length, it will have gained two feet additional length, 

 juid 24 times one inchj, are equal to 32 inches, equal to 8 inches girt, 

 added to its prefent meafure 19 inches, are equal to 27 inches ; then 

 42 feet by 27 inches, are equal to 21 2 feet, feven Inches ; fo that in 

 24 years it will gain 112 feet, viz. it will more than double its pre- 

 fent contents, which it has been fixty years at leaft in attaining.— 

 May this prove an incitement to thofe who have thriving trees, to 

 preferve them, till they have apparently done growing !
