In the same park, in the place there call'd the 

 Hawks-nest, are trees forty foot long of timber, which 

 will bear two foot square at the top-end or height of 

 forty foot. 



If then a square whose side is two foot, be inscribed 

 in a circle, the proportions at that circle are

And because a tun of timber is said to contain forty 

 solid feet : one of these columns of oak will 

 contain above six l tun of timber and a quarter : 

 In this computation taking them to be cylinders, 

 and not tapering like the segments of a cone.

 Grindal Oak, hath at these several distances from the

The breadth is from bough-end to bough-end (i.e.) 

 diametrically 88 foot ; the height from the ground to 

 the top-most bough 8 1 foot [this dimension taken from 

 the proportion that a gnomon bears to the shadow] 

 there are three arms broken off and gone, and eight 

 very large ones yet remaining, which are very fresh 

 and good timber. 



88 foot is 29 \ yards, which being in this case 

 admitted for the diameter of a circle, the square 



1 A statutable tun of timber is by some reckon'd 43 foot of solid : and to a load 50.
