of air which happen whenever tliC liighcr la^ds receive the firfi: un- 

 preffioii of the lea winds, or retain tliem longer; the clouds at 'iivi-i 

 times being elevated to confiderable he.ght, and rnovin'- in tlic

 until the rcliftance of inch lofty mafles rebuffs the current d^rvvn 

 upon the inferior fituations ; fo that, wh.ilfl: the ivniJiitanrs here 

 feel the impreflion of it from the Weftu'ard, or North-Wefl, thcv 

 fee with furprize a feud flying over tlieir heads in a contraiy di- 

 rection; but generally a little time clears up all doubts; a fuf- 

 penfion follows of the land current, or a temporary calm, fucceeded 

 by a South-Eaft or Soutlierjy gale, and torrents of rain. 



The figure in the annexed plate reprefents the ifland extending 

 longitudinally, Eafl: to Well, interfeded by chains of high moun- 

 tains. Erom the feet of thefe to the South-fide coad, and the like 

 in mofl parts of the North-fide, the ground gently Hopes by a fmall 

 declivity to the fea. The fea-breeze, whilft it continues in the 

 Eafl: and South-Eaft points, blowing upon the Eall: end, is divided 

 in its current, palfing in curved lines along the two oppofite coafts 

 of North and South. When the fun approaches the Northern 

 Tropic, the fea-breeze declines more Southerly ; and then follows 

 the fun's track, only varying fome few points in the courfe of 

 the day. This is particularly obfervable in June. 



When the fun riles North-eaft, the morning breeze fets from the 

 fame quarter; but, as the former continues its progrefs, the latter 

 will apparently diverge to the Southward, till the fun fets in the 

 North-well:, at which time the breeze feems to come from tlie 

 South-eafl:. So, when the fun returns again to vifit the Tropic 

 of Capricorn, the further he declines towards South-wefl", the 

 more will the breeze recede towards the North-eaft and Northerly 

 points. When he fets in the South- weft quarter, the denle air 

 from the North gains upon the ufual trade-wind, and grows more 

 vigorous, neceflarily haftening towards thofe regions where the at- 

 mofphere is in a ftate of greateft rarefaction. The Norths at this 

 time fet-in early in the evening, and continue till late in the 

 morning ; and the fea-breeze is proportionably diminilhed in- 

 ftrength and continuance. When therefore the fun riles in the 



Suuth-eaft,
