GREENLAND VOYAGE.

of the cabin-stove, which had inadvertently been 
made of sheet-iron, and had consequently an at¬ 
tractive energy (according to Mr Barlow’s in-r 
vestigations), equal to a pillar of solid metal, of 
the same quality and diameter. On removing 
this chimney, though eight feet distant from the 
binnacle, the deviation was diminished more than 
two-tliirds.—Saw a number of small whales of the 
the Dolphin genus (Delphinus deductin' of Dr 
Traill), some of which followed the ship, and 
came within pistol-shot. A great quantity of 
kitty wakes (Lams rissa) were also about us. 
In many places the surface of the sea was mark¬ 
ed by large shining veins, the effect of an oleagi¬ 
nous exudation, probably either of the dolphins 
or of the fishes on which they feed. 
On Sunday the 21st of April, we had a hard 
gale from the NE. and NNE., which being di¬ 
rectly against us, put us under close-reefed top¬ 
sails and courses. As we were warned of this 
gale, by the fall of the barometer, we made all 
snug the night before it came on, and were ful¬ 
ly prepared for it.—Had Divine Service, as usual, 
morning and afternoon, with the religious exer¬ 
cises of the apprentices in the evening. 
The wind moderated at sun-rise of the 22d, 
and veered to the south-west; but as the sea con¬ 
tinued to run remarkably heavy, we obtained very 
little advantage from the fair wind.
