at the time on Eafthwaite- water, a lake about a mile 
and half in length, lying near this town. 
In all my inquiry, my Lord, I cannot find, that 
any motion or tremor of the ground was perceived 
by any one. And as to the differences of the time 
the agitations lafted, may they not be thought pro- 
portionate to the different dimenfions of the lakes, 
as the vibrations of pendulums, after the impelling 
powers are taken away, may be found to continue in 
proportion to their lengths. Upon the whole, tho’ 
the feveral agitationir above-mentioned are undoubt- 
edly matters of fadt, yet had there, at the time they 
happened, been a ftrong wind, the phasnomenon 
would perhaps have been loft among the common 
waves ; and as no motion or tremor of the ground 
was perceived, does it not feem hard to account for 
this motion of the waters from a fubterranean caufe? 
Or may it not rather be deemed owing to fome hid- 
den alteration in the preffure of the atmofphere ? 
But I Ihall tire your Lordfhip, and beg pardon, who 
am, 
My Lord, 
Hawkefhead, 
Dec. 24, 1755. Your Lordlhip’s moft dutiful and 
moft obedient humble fervant, 
John Harrifon.
