The man was, however, obstinate--or, at least, so he seemed to me to be--resolutely declining to accede to either of my suggestions; so, leaving him to complete the few remaining preparations I deemed necessary to meet an attack, should anything of the sort be attempted, I returned aft to the poop, somewhat vexed that so thoroughly sensible a man as Roberts had hitherto proved should suffer himself to be so completely mastered, as I had seen him to be, by a morbid feeling of melancholy that was doubtless due in part to overmuch dwelling of late upon the death of his wife but which I firmly believed was to be still more directly traced to some slight derangement of the system that could easily be put right by the administration of a dose of medicine, could the fellow but be induced to take it. No doubt, too, the fact of our being becalmed, and therefore to a great extent helpless, in a spot notoriously haunted by a people, every mother's son of whom was but too ready to participate in any act of piracy that seemed to offer a reasonable prospect of success, had a large influence in producing the presentiment of death in the mate's mind; but that, I felt sure, would pass away with the impenetrable and oppressive darkness by which we were enveloped, or with the advent of a breeze of wind. While, therefore, I sincerely pitied the poor fellow for his disagreeable state of mind, I thought that perhaps it would be wisest to treat it as a matter of no importance, and to leave him to himself until the fit of depression should have passed away.
