Thus fummcr tempefts always tend to diminifh the fuperficial 

 heat of an ocean over which they rufli ; while winter blafts, agi- 

 tating the- waters at confiderable depths, refift the natural cold of 

 the feafon by a fupply of relatively warm particles, which arifc 

 from the bottom toward the furface. 



That the Atlantic ocean, the vaft and potent arbiter of our 

 feafons, has fuffered unufual agitation of late years, feems evident 

 from the natural phaenomena recorded in the beginning of this 

 Memoir. The trees, and fands of our ifland, bear teftimony to 

 the ftorms which fweep along its furface ; and the tides come to us 

 as frequent, and unerring meflengers of the tumultuous and 

 agitated ftate of its billows, attendant on their furious career. 



From this perturbed abyfs of waters has arifen an unceafing 

 influence, equally potent to check the ardour of the fummer 

 folar beams, or to relax the fhackles of a northern winter. By 

 this prevailing influence fummer has been rendered impotent to 

 raife and ripen many of our crops, and the farmer, taught by ne- 

 ceflity, learns now to hand them over ready grown, and prepared 

 for the maturity of fummer, under the mild temperature of an 

 Atlantic winter. Hence too the gardener has, of late years, been 

 compelled to call in the aid of artificial heat to forward the peach, 

 the nedarine, the grape, and every other fpecics of delicate fruit, 

 to perfedion.
