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.
