general outline. Upon the north eastern side the lower 
some resemblance to a shoe. 
Mr. W. observes, “ the lower side, on the East, is arched 
_ from the middle to the northern end, where in descending 
it terminates ina short rounded projection, upon which ‘this 
end is supported, as may be seen in the N. E. view :* from 
the middle to the southern end, itis nearly upon a straight 
line; the point upon which this end rests is not so evident 
as the other. It is marked by the letter A in the N. Ey 
view The average elevation from the lower rock, on the 
east, is about an inch and a half. On the west the lower side 
is gradually elevated from the northern to the southern end; 
where it is raised a footand a half from the supporting rock. 
On the western side of the northern end the weightiest part 
is at the bottom, but on the eastern side at the top.” 
By a line drawn around it, from end to end, Mr. P. found 
its largest circumference to be thirty seven feet and four 
inches ; its smallest twenty feet and eight inches. From its 
irregularity, he could not obtain its cubie dimensions with ac- 
curacy ; but concluded that it was equal:to-a regular solid of 
teen feet in length, six in breadth, and six in thickness ; 
quivalent to five hundred and forty cubic feet. A small stone 
of a regular form composed of the same ingredients as the 
moveable stone, and containing by admeasurement thirty six 
cube inches, he found to weigh four pounds ; which is atthe 
rete of one hundred and ninety two pounds the cubic foot. 
Consequently, the weight of the rocking stone is one hundred 
aud three thousand, six hundred and eighty pounds, or forty 
six tonsand upwards. A child sixyears of age can easily move 
it with one hand, and any adult person with a single finger ; 
indeed Mr. P. could move it very perceptibly with the little
