ON DECK 103 between its main and fore masts? Is it a boat worked by electricity, with either a battery of accumulators or coils of considerable power, which work its screw and give it such speed ? In fact, I cannot account for this navigation in any other way. In any case, since the propeller can only bea screw, I shall see it working by leaning over the taffrail, and I shall then have only to recognize the mechanical source of the movement. The man at the wheel glances at me scornfully, but allows me to approach. I lean over and I see— Not a trace of the boiling and whirling which the rota- tion of the screw produces. Nothing but a smooth track extending for three or four cable-lengths, such as a ship in full sail leaves behind her. But what is the motor that drives the schooner with such marvellous speed? I have said that the wind is unfavourable, and the sea rolling in long, unbroken undulations. I will know, however, and, as the crew take no notice of me, I again turn towards the bows. As I reached the companion I found myself in the presence of a man whose face was not unknown to me. With his arms resting on the edge of the skylight, he watched me as I draw near. He seems waiting for me to speak. My memory comes back again. This is the man who accompanied Count d’Artigas on his visit to Healthful House. Yes! there is no mistake.
