Remarks.—When at the summit, or just 
before, we had a hail-shower; clouds in va- 
rious strata, some above and others below the 
summits of the mountains—very wild and 
threatening appearance—a great snow-drift . 
in the usual place. Got the cramp in my feet 
by standing on ita short time. A gentleman 
and his two daughters were in company with 
me in this ascent. Soon after our descent, 
which luckily was without rain, we posted to 
Keswick, and on the road at 6 P.M. en- 
countered a tremendous thunder-storm. On 
going into Keswick the rain was heavier than 
I ever remember.
