very temperate, rather cool than warm ; and fo con- 
tinued till Thurfday the 14th. 
In my journal for Wednefday the 13th I find the 
following remarks, viz. “ This evening’s tide” (from 
6 A. till 12 A.) “ the wind at eaft, but moderate,. 
“ with frequent flafhes of lightning to the fouth- 
ward. Soon after we got on board the ftore- 
“ veffel, a fquall of wind arofe from the fouth-weff 
“ on a ludden, and continued for about a minute 
“ part of which time it blew fo hard, w'-e expedted 
u the mads to go by the board : after which it was 
<f perfectly calm, and prefently after a breeze re- 
“ turned from the eaft.” 
And in the journal of the 14th is entered, cC This 
<c morning’s tide” (viz. from 1 M. to 1 A.) “ the 
“ air and fea quite calm.” 
Hence it appears, how different the temper of the 
air may be in a fmall diftance ; and to what lmall 
fpaces fqualls of wind are fometimes confined. 
It may not be amifs further to obferve upon this 
head, that once, in returning from Edyflone, having 
got within about two miles of the Ramhead, we 
were becalmed ; and here we rolled about for at lead: 
four hours ; and yet at the fame time faw veflels^ 
not above a league from us, going out of Plymouth 
Sound with a frefh of wind, whole direction was 
towards us, as we could obferve from the trim of 
their fails ; and as we ourfelves experienced, after 
we got into it by tacking and rowing. 
I am, Sir, 
Your molt humble Servant, 
J. Smeaton.
