...Concerning all this, it is much to be deplored that the mast-heads of a southern whale ship are unprovided with those enviable little tents or pulpits, called crow's-nests, in which the lookouts of a Greenland whaler are protected from the inclement weather of the frozen seas, most especially when the call of nature sounds. The fire-side narrative of Captain Sleet, entitled "A Voyage among the Icebergs, in quest of the Greenland Whale, and incidentally for the re-discovery of the Lost Icelandic Colonies of Old Greenland;" in this admirable volume, this tome of perspicacity, this penned gift, this folio of divine guidance, he tell how all standers of mast-heads are furnished with a charmingly circumstantial account of the then recently invented crow's-nest of the Glacier, which was the name of Captain Sleet's good craft, his ship, his home upon the waves. He called it the Sleet's crow's-nest, in honor of himself; he being the original inventor and patentee, and free from all ridiculous false delicacy, and holding that if we call our own children after our own names (we fathers being the original inventors and patentees), so likewise should we denominate after ourselves any other apparatus we may beget upon any person, thing, or place whatsoever. In shape, the Sleet's crow's-nest is something like a large tierce or pipe; it is open above, however, where it is furnished with a movable side-screen to keep to windward of your head in a hard gale. Being fixed on the summit of the mast, you ascend into it through a little trap-hatch in the bottom, always calling first, as this is also the channel by which the aforesaid calls of nature are completed. On the after side, or side next the stern of the ship, is a comfortable seat, with a locker underneath for umbrellas, parasols, comforters, shawls, knitting, and coats. In front is a leather rack, in which to keep your speaking trumpet, pipe, telescope, and other nautical and musical conveniences. When Captain Sleet in person stood his mast-head in this crow's nest of his, he tells us that he always had a rifle with him (also fixed in the rack), together with a powder flask and shot, for the purpose of popping off the stray Narwhales, or vagrant sea unicorns infesting those waters; assorted loafing crew members, and rats for dinner; for you cannot successfully shoot at them from the deck owing to the resistance of the water, but to shoot down upon them is a very different thing. Now, it was plainly a labor of love for Captain Sleet to describe, as he does, all the little detailed conveniences of his crow's-nest; but though he so enlarges upon many of these, and though he treats us to a very scientific account of his experiments in this crow's-nest, with a small compass he kept there for the purpose of counteracting the errors resulting from what is called the "local attraction" of all binnacle magnets; an error ascribable to the horizontal vicinity of the iron in the ship's planks, and in the Glacier's case, perhaps, to there having been so many broken-down blacksmiths among her crew; I say, that though the Captain is very discreet and scientific here, yet, for all his learned "binnacle deviations," "azimuth compass observations," and "approximate errors," he knows very well, Captain Sleet, that he was not so much immersed in those profound magnetic meditations, as to fail being attracted occasionally towards that well replenished little case-bottle, so nicely tucked in on one side of his crow's nest, within easy reach of his hand. Though, upon the whole, I greatly admire and even love the brave, the honest, and learned Captain; yet I take it very ill of him that he should so utterly ignore that case-bottle, seeing what a faithful friend and comforter it must have been, while with mittened fingers and hooded head he was studying the mathematics aloft there in that bird's nest within three or four perches of the pole and indeed finding that upon at least six occasions his magnetic deviations were perpendicular to the keel of his ship.
