Then further it is demonstrable in geometry, that half the diameter 

 multiplied into half the circumference, produces the area or quan- - 

 tity of the circle, and that will be found to be 754f H, which is 

 755 square yards^em 



Then lastly, if a horse can be limited to three square yards of ground 

 to stand on, (which may seem a competent proportion of three yards 

 long, and one yard broad,) then may two hundred and fifty-one 

 horses be well said to stand under the shade of this tree. But of 

 the more northern cattle, certainly above twice that number. 



WORKSOP PARK. 



In this park, at the corner of Bradshaw-rail, lieth the bole of an Oak- 

 tree, which is twenty-nine feet about, and would be found thirty if it Hen. Homer, 

 could be justly measured, because it lieth upon the ground ; and the 

 length of the bole is ten feet, and no arm or branch upon it» 



In the same park, at the White Gate, a tree did stand, that was from 

 bough-end to bough-end (that is, from the extreme ends of two opposite Ge'o^Ma-son. 

 boughs) one hundred and eighty feet; which is witnessed by Jo. 

 Magson and George Hall, and measured by them both. 



Then because 180 feet, or 60 yards, is the diameter, 30 yards will be 

 the semi-diameter : and by the former analogies

That is, the content of ground upon which this tree perpendicularly 

 drops, is above 2827 square yards, which is above half an acre of 

 ground: and the assigning three square yards (as above) for a 

 horse, there may 942 be well said to stand in this compass. 



In the same park (after m'any hundreds sold and carried away) there is 

 a tree which did yield quarter-cliff bottoms that were a yard square ; and jo. Magson.
