an hideous dull Noife railed their Curiofity 5 and they 
oblerv’d that the whole Space A. B. C. D. containing a - 
bout three Irijh e. 4 \ Exglifj) Acres, had been all 
Day in a gentle Motion : And the Noife continued all 
Night, occafion’d by the rubbing of Bufhts, tearing of 
Roots, rending and tumbling of Earth. The Motion 
ceas’d on Wednefday after Noon $ when they faw the 
Bufhes on the Bank E. F. were remov’d* fome (landing 
and fome overthrown, to the plain Meadow T.ji. The 
geeen Ground above E. F. when it came to the top of 
the deep Part at E. F ’. rent with hideous Chafms, ten, 
fifteen, or twenty Feet deep, and tumbled down in Rolls 
of a Yard or two thick, and ten or twenty long and 
broad 5 not unlike a fmooth Water breaking over a 
Cataradl, and tumbling in Waves below. 
There was a Precipice at the Top X. x. 6 5 Feet Per- 
pendicular, making the Slope Line X. x. 12 6 Feet. The 
Ground from x. to L, was made more level, the whole 
Perpendicular Height of x. not exceeding the Plain of 
L. above 30 Feet ; but the Ground at L. in the whole 
Line from E. to F was mounted above 20 Fee? higher 
than the unmoved Ground on either fide at £. and F. 
and the Height of L. above the Plain of y. is 55 
Feet. 
There was a Ditch H, I. went crofs the Ground 3 
which being broken off at 0.0. is- removed together 
with the moving Part 34 Feet lower down than the 
immoveable $ but at the Bottom y. it is tumbled 60 Feet 
over the Plain Meadow. The Breadth at the Bottom a. b, 
is 400 Feet, and at c. d< about 300. 
The whole Face of the Precipice X x. is of a blue 
Clay, mix'd with many little blue Stones. TheMettalis
