Since then the trees, the fands, and the tides demonftrate that 

 thefe winds have, of late years, blown with unufual violence ^ 

 fince they bear teftimony that a large quantity of air, thus diredled, 

 thus tempered and furcharged, has pafTed over our lands j 

 it plainly follows that the climate muft have felt the change ; 

 that it muft have experienced colder fummers and milder winters 

 than heretofore, approaching towards that equability of heat, and 

 redundance of moifture, which the farmer and the gardener at 

 prefent fo heavily lament. 



But it is not from encreafe of quantity alone that thefe winds 

 have produced their effedts. They have altered the temperature 

 of the ocean itfelf ; and thus have, as it were, multiplied their 

 changeful influence on the land ; ading there, at once, with new 

 properties, as well as with encreafed quantity. 



The furface of water, in a ftate of tranquillity, admits of greater 

 variations of temperature than in a ftate of agitation. It may 

 become much hotter in fummer, and colder in winter, when calm, 

 than when difturbed : for the particles at the furface, when 

 heated or cooled, do not immediately give place to others nearer 

 the bottom -, the procefs of commixture, in a tranquil ftate, is 

 gradual, and thfc tranfmiifion of change fomewhat refembles the 

 flow and retarded progrefs that takes place on the land. Agitation 

 always counterads'this gradual procefs ; a rapid commixture of the 

 particles produces a quick aflimilation of temperature throughoist 

 the whole mafs, and thus, taking away all partial excefs, reduces 

 the whole toward a medium ftate of uniformity.
