By this time I had completely recovered, not only from the effects of the snake-bite--at which my companions seemed greatly astonished--but also from the hardship and privation which I had experienced during the latter part of my voyage aboard _La Mouette_, and had begun to think very seriously of how I was to effect my escape from those who held me captive.  Not that I was ill-treated by them, far from it; I enjoyed the same fare as themselves, and was never asked to share their labours, and that, I take it, was as much good treatment as I could reasonably expect under the circumstances.  But I knew that they were not hampering themselves by taking me and their other prisoners this long journey up the river--much of the paddling being done against the stream--merely for the pleasure of enjoying our society.  My intuition assured me that their action had a more sinister motive than this, and in any case I had no desire to penetrate the interior of equatorial Africa; therefore so soon as I felt that my health and strength were sufficiently restored to allow of my attempting the long and perilous journey back to the sea alone, I began to consider the question of escape.  But the longer I thought of it the less became my hope of success; for I very soon discovered that under no circumstances whatever were my custodians disposed to allow me to stray a yard out of their sight.  Without imposing any actual restraint upon me, they invariably so contrived that, if I made the slightest attempt to withdraw myself from them, three or four of the most active of the party, always well armed, had occasion to go in precisely the same direction as myself.  That, however, was not my only difficulty; for, assuming for a moment the possibility of my being able to give the savages the slip, how was I, a white man, alone, unarmed, and with no means of obtaining food, to make my way down more than two hundred miles of river, flowing through a country every inhabitant of which would undoubtedly be an enemy, whose delight it would be to hunt me to death?  I told myself that if I could obtain a small, light, handy canoe and weapons, even though they should but consist of a bow and arrows, the situation would not be altogether hopeless--for I possessed a very fair share of pluck and resource; but I felt that before I could effect my escape from my watchful custodians, and obtain these necessities, I might find myself in so dire a strait as to render them and all else valueless to me.  Yet I would not suffer myself to feel discouraged, for I recognised that to abandon hope was to virtually surrender myself tamely to the worst that fate might have in store for me, and this was by no means my disposition; I therefore continued to keep my eyes wide open for an opportunity.
