Ignorance and superstition ever bear a close, and even a mathematical relation to each other. The degrees of the one are regulated by the degrees of the other. He who knows the least believes the most; while he who has seen the most, without the intelligence to comprehend that which he has seen, feels, perhaps, the strongest inclination to refer those things which to him are mysteries, to the supernatural and marvelous. Sailors have been, from time immemorial, more disposed than men of their class on the land, to indulge in this weakness, which is probably heightened by the circumstance of their living constantly and vividly in the presence of powers that menace equally their lives and their means, without being in any manner subject to their control. Spike, for a seaman of his degree of education, was not particularly addicted to the weakness to which we have just alluded. Nevertheless, he was not altogether free from it; and recent circumstances contributed to dispose him so much the more to admit a feeling which, like sin itself, is ever the most apt to insinuate itself at moments of extraordinary moral imbecility, and through the openings left by previous transgression. As his brig stood off from the light, the captain paced the deck, greatly disturbed by what had just passed, and unable to account for it. The boat of the Poughkeepsie was entirely concealed by the islet, and there existing no obvious motive for wishing to return, in order to come at the truth, not a thought to that effect, for one moment, crossed the mind of the smuggler. So far from this, indeed, were his wishes, that the Molly did not seem to him to go half as fast as usual, in his keen desire to get further and further from a spot where such strange incidents had occurred. As for the men forward, no argument was wanting to make _them_ believe that something supernatural had just passed before their eyes. It was known to them all that Mulford had been left on a naked rock, some thirty miles from that spot; and it was not easy to understand how he could now be at the Dry Tortugas, planted, as it might be, on purpose to show himself to the brig, against the tower, in the bright moonlight, “like a pictur’ hung up for his old shipmates to look at.”
