in not lefs than two hundred barks, viflt Bergen every year, at the 

 fair and the afiizes, and moft of whom have upwards of an hun- 

 dred leagues to fail, are often favoured with the north and fouth 

 winds, like regular trade- winds, though not fo infallibly to be de- 

 pended on. The wind which is, with the greateft certainty, ex- 

 pected towards harveft, is the north- eaft, called Hambakke, which 

 name it derives from the melting of the fnow at that time from the 

 fummits of the mountains; but there is alfo here, in fummer time, 

 and in a clear fky, another kind of a daily trade-wind along the 

 coaft, and in the creeks, known by the general appellation of 

 Soelgangs-Veyr, the weather of the fun's courfe ; and in North- 

 land, Soelfar-Vind (the wind of the fun's courfe) the wind

tive to the fun, which in the morning heats the coaft, and confe- p. 65. 

 fequently rarities the air, but on its declenfion in the evening, the 

 air cools, and confequently recovers its gravity, and being thereby 

 become heavier than the fea-air, its own weight carries it thither, 

 and occasions a kind of ebb and flood in the air, the fluid parts 

 whereof undergo the fame agitation as water *. A little before 

 noon in the fummer time, comes on a weft, fouth- weft or north- 

 weft breeze, and holds till towards midnight; it is called Hafgul, 

 (fea-cooler) as coming from the fea, and indeed it tempers the heat, 

 which otherwife in the creeks and narrow valleys, would be infup- 

 portable. Oppofite to this is the Landgul ( land- cooler) or eafterly 

 breeze, which beginning at midnight, or two hours after, continues 

 till within two hours of noon, when it ufually ceafes ; towards har- 

 veft the land-cooler begins to get the afcendant, and the fea-cooler 

 to relax, and then the former is called the Korn-moen, i. e. Corn- 

 mother, bringing a feufible warmth along with it. 



Befides thefe regular winds, the coaft is fubjecl: to Field-flagers 

 (mountain fqualls) or gufts from the land, by which, without the

 Greece, " Quod ad Etefias attinet, caufam harum ajunt effe refolutionem nivium 

 in hyberboreis fuppolaris regionis montibus, quas uti a folis radiis veroerate atque

 p. 196. Likewife Dr. Arbuthnot in his Treatife of the Effects of the Air upon the 

 Human Body : " The winds, when ftrong, correfpond to each other ; but, when 

 they relax, they differ, as this proceeds from local caufes. It is alfo clear that the 

 Alpine fnows influence the weather in England, as well as that at Zurich."
