I could scarcely believe my ears when I heard Fernandez give this extraordinary and, as I deemed it, most imprudent order.  It seemed too good to be true!  Why, if the foolish man had but known it, there was nothing I could possibly have more ardently wished for than liberty to range freely the settlement and become fully acquainted with all its resources!  If I had ever dreamed of such a possibility as this it would not have needed that I should be brought a prisoner to the place; I should have been but too eager to make my way to it voluntarily.  But, of course, it was much better as it was, for now all that I had to do was to keep my eyes and ears wide-open, learn everything I possibly could, and, generally, make the very best use of my time before the return of Garcia, while humouring Fernandez to the top of his bent in his delusion that he would ultimately convince me of the advantage of joining the band.  Moreover, I believed I should not have much difficulty in accomplishing this last; for, although I was at first somewhat at a loss to understand his great eagerness to secure me as a recruit, it became perfectly intelligible when I learned a little later on that the only weak point in the entire scheme consisted in the extreme scarcity of trained sailors capable of undertaking the more important executive duties.  Seamen, of the kind to be found in a ship's forecastle, they possessed, not exactly in abundance, but sufficient for their ordinary necessities; but it appeared that, apart from Garcia, his first lieutenant, and one other, they had not a single navigator among them; and it was easy to understand that, if anything untoward should happen to either of these men, the activities of the brotherhood would be seriously crippled, while a fatality that swept the whole of them away might well mean the utter ruin of all their hopes.  I did not learn this quite at once, for it seemed to be the one item of information upon which Fernandez desired me to remain ignorant; but, mingling freely with everybody, as I was permitted to do, it was impossible for them to prevent the secret from ultimately leaking out, and I had not been in the settlement more than three days before I became acquainted with it, and with a good many other things as well.
