A DISCOURSE 



BOOK III. there is of them to be seen at Worksop at this day, and some tables 

 ' made of the same quarter-cliff likewise. 



In the same park, in the place there called the Hawk's Nest, are trees 

 40 feet long of timber, which will bear two feet square at the top end 

 or height of forty feet. 



If then a square, whose side is two feet, be inscribed in a circle, the 

 proportions at that circle are. 



• A statutable 

 ton of timber 

 is, b}' some, 

 reckoned forty- 

 three feet of

 load, fifty.

And because a ton of timber is said to contain forty solid feet, one of 

 these columns of Oak wiU contain above six tons of timber, and 

 a quarter *; in this computation they are taken to be cylinders, 

 and not tapering like the segments of a cone. 



WELBECK LANE. 



The Oak which stands in this lane, called Greendale Oak, hath, at 

 these several distances from the ground, these circumferences :

The breadtji is, from bough-end to bough-end, diametrically 81 feet ; 

 the height from the ground to the topmost bough, 88 feet [This dimen- 

 sion 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. 



Eighty-eight feet is 29^ yards, which being in this case admitted for 

 the diameter of a circle, the square yards in that circumference will
