Laftly, the faid top increafes to 28 inches girt, 

 and the additional length of timber, being la feet 

 at 24 inches girt, equal to one ton eight feet, fet 

 down as the meafure of the branches j which, it may 

 be obferved, are here ilippofed to lengthen more 

 t^an in proportion to a foot in a period, though the 

 Ihaftwas confined to that extent -, as in fad branches 

 when they become timber, always do. For being 

 of great length, before they attain meafurable fub- 

 fiance j upon their increafe in bulk, the menfuration 

 extends as rapidly at leafl, as the progrefs here af- 

 ligned to it; viz, from two to three [feet in 12 or 

 14 years. Thus large branches in oak, contribute 

 greatly to the increafe and value of the timber, as 

 is evident by that of Langley- Wood. 



In the manor of Dibden, belonging to Lord 

 MalmA)ury, on the eaftern bounds of the New 

 Foreft, are fome capital oaks s one in particular is 

 larger than Fyfields at equal diftance from the 

 ground, but inferior to it in height and folid con- 

 tents. This is II feet eight inches round; at fix 

 feet the fhaft is ftraight, and exceeds 30 feet in 



length;
