For the rest of that day, and for the two days following, Captain Luke did not in any way refer to his offer; and as he showed himself more than ever friendly, and talked away to me in his usual entertaining fashion, my rage and fright began to go off a little--though at bottom, of course, there was no change in my opinions, nor any doubt as to my giving him a point-blank refusal when the issue should be squarely raised. All this time the brig was bowling along down the trades; and on the third morning after I had the captain's offer--we being then close upon the thirty-fifth parallel of north latitude--Bowers called my attention to the gulf-weed floating about us, and told me that we were fairly on the outer edge of the Sargasso Sea. We should not get into any thicker part of it, he said, as we should bear up to clear it; and so we actually did, hauling away a good deal to the eastward when the brig's course was set that day at noon. But my interest in the matter had been so checked--all my thought being given to finding some way out of the pickle in which I found myself--that I paid little attention to the patches of yellow weed on the water around us or to the bits of wreckage that we saw now and then; and when Bowers, keeping on with his talk, fell to chaffing me about my desire to make a voyage of discovery into the thick part of this floating mystery I did not rise to his joking, nor did I make him much of a reply. Indeed, I was in rather a low way that day; which was due in part to my not being able, for all my thinking, to see any sort of a clear course before me; and in part to the fact that the weather was thickening and that my spirits were dulled a good deal by what we call the heaviness of the air. All around the horizon steel-gray clouds were rising, and a soft sort of a haze hung about us and took the life out of the sunshine, and the wind fell away until there was almost nothing of it, and that little fitful--while with the dying out of it the sea began to stir slowly with a long oily swell. Far down to the southeast a line of smoke hung along the horizon, coming from the funnel of some steamer out of sight over the ocean's curve, and the heaviness of the atmosphere was shown by the way that this smoke held close to the surface of the sea.
