As I know now, Bowers over-estimated the size of this strange island of sea-waifs and sea-weed by nearly one-half; and he was partly wrong as to the making of it: for the Sargasso Sea is not where any current ends, but lies in that currentless region of the ocean that is found to the east of the main Gulf Stream and to the south of the branch which sweeps across the North Atlantic to the Azores; and its floating stuff is matter cast off from the Gulf Stream's edge into the bordering still water--as a river eddies into its pools twigs and dead leaves and such-like small flotsam--and there is compacted by capillary attraction and by the slow strong pressure of the winds. On the whole, though, Bowers was not very much off in his description--which somehow took a queer deep hold upon me, and especially set me to wondering what strange old waifs and strays of the ocean might not be found in the thick of that tangle if only there were some way of pushing into it and reaching the hidden depths that no man ever yet had seen. But when I put this view of the matter to him I did not get much sympathy. He was a practical young man, without a stitch of romance in his whole make-up, and he only laughed at my suggestion and said that anybody who tried to push into that mess just for the sake of seeing some barnacle-covered logs, or perhaps a rotting hulk or two, would be a good deal of a fool. And so I did not press my fancy on him, and our talks went on about more commonplace things. It was with Captain Luke that I had most to do, and before long I got to have a very friendly feeling for him because of the trouble that he took to make me comfortable and to help me pass the time. The first day out, seeing that I was interested when he took the sun, he turned the sextant over to me and showed me how to take an observation; and then how to work it out and fix the brig's position on the chart--and was a good deal surprised by my quickness in understanding his explanations (for I suppose that to him, with his rule-of-thumb knowledge of mathematics, the matter seemed complex), and still more surprised when he found, presently, that I really understood the underlying principle of this simple bit of seamanship far better than he did himself. He said that I knew more than most of the captains afloat and that I ought to be a sailor; which he meant, no doubt, to be the greatest compliment that he could pay me. After that I took the sights and worked them with him daily; and as I several times corrected his calculations--for even simple addition and subtraction were more than he could manage with certainty--he became so impressed by my knowledge as to treat me with an odd show of respect.
