172 ON THE EFFECTING OF 



probably not blowing at one extremity of the flaw, pro- 

 duces its preponderating eflects at the other. Masters of 

 ships are cautious of remaining in such a situation as places 

 them in the course in which the tlaw is observed to move ; 



it may be seen that the patches of cirrostratus, in their bases, pointed 

 to the quarter whence the succeeding wind came. This cloud may 

 be deemed to announce the earliest wind, whilst the ciiTus points to 

 one remotely distant, and which in its coming is liable to interruption. 

 This distinction may be of use if judiciously applied. 



This period of the season is remarkable for the progress of the 

 whale northward : heavy packs of ice, and bergs around : north-west 

 of Disko still in sight, five or six leagues distant : upper region of 

 atmosphere overcast with drifting cirrostratus, which clearing at 

 intervals exhibited cuTocumulus, and subsequently cirrus : this latter 

 cloud, at a later hour, moved off in the direction of the wind above 

 noted ; hence it is likely to continue, as it occupies so large a portion 

 of the atmosphere : this evening afforded a clear view of the lofty 

 peaks on the Waygat side of Disko, which towered above the moun- 

 tain, as it bends its rocky prominences to the north-west : probably 

 the highest mountain in Greenland is one of these : it rises greatly 

 above the rest, and is visible across the whole north-west end of Disko : 

 by calculation it must be one half as high again as the land at 

 Fortune Bay. 



June 19: ther. 32°, 36°, 34°: wind N.E., strong breeze: it is 

 remarked, that the prevailing winds along the coast are N. or S. :
