utmoft precaution a veffel is fuddenly loft in the fecurity of fine 

 and calm weather; for thefe blafts iffuing in a narrow and violent 

 current from the clefts of the mountains^ or from the vallies, be- 

 hind a cape, or from the points of the high mountains, and being 

 violently impelled agarnft an oppofite mountain, this reverbera- 

 tion caufes a kind of hurricane in the air, which, for a time, may 

 deprive the unwary of his fight *. 

 Hurricanes But the real hurricanes, or whirlwinds, which arife, though 

 winds. ir " feldom on the open fea, are known to be extremely dangerous to 

 fhips, by their fudden and rapid vortex, which throws the fea 

 at a fmall diftance into fuch an agitation, that the water in drops 

 flies up into the air like fmoke. The common people, from an 

 old fuperftition, call them Ganfkud, conceiting that a necro- 

 mancer, of Fin-lapland, has then fent out his Ganfly, as they 

 call it, to do mifchief ; but the true caufe of the hurricane, is the 

 fudden explofion of a wind confined and agitated in a thick cloud, 

 which being impetuouily difcharged upon the water, the furface 

 is feparated, and rifes np into tke air like duff: or fmoke, and 

 hence, amongft us, this hurricane is very properly called Roeg- 

 flage, i. e. fmoke-fquall. 



I fhall take this occafion to mention another wonderful phe- 

 nomenon of the air, which likewife proceeds from denfe, and vio- 

 lently agitated clouds, not as any thing new and unknown in the 

 warm climates, but as being, however, fomewhat rare, and by 

 experience very well known in the north. I mean the water- 

 Water-fpout. fpout, or Trompe de mer, of which a credible perfon, who fpent 

 his younger years at fea, gave me the following account ; that on 

 the wide fea, betwixt Shetland and Norway, he and his crew, to 

 their great aftonifhment, obferved, in clear weather, and an eafy 

 breeze, a cloud gradually defcending towards the water, and in 

 the fhape of a funnel, or rather a fpiral fnail-fhell, attracting from 

 the furface of the fea a column of water of a coniiderable diame- 

 meter ; and this fudion continued all the time they were in fight. 

 Some hours after came on a very violent rain, which, unqueftion™

 whirlwind, and driven back by another ftronger wind meeting him, without any 

 damage to either man or horfe, muft reft upon the authority of a very credible
