"Ready all, in the cutter!" cries the doctor. "Off!" and next moment we are flying through the water in full cry. As we gradually pull up to the duck he diminishes his pace, and finally lies on his oars and coolly waits for us. "Put it on, now!" calls out our coxswain, and our boat shoots forward. When within a few yards, the duck, apparently alive to his danger, dashes his oars into the water and darts ahead. But we are too fast for him. Another two strokes and we shall row him down. "Now then!" cries our coxswain. Ah! At a tremendous pace our boat flew forward over the very place where, a second before, our duck had been. But where was he? By a turn of the hand he had twisted round his punt, and as our fellows dug their oars wildly into the water and tried to pull up, there was he, calmly scuttling away in an opposite direction, and laughing at us! In due time we had swung round, and were after him again, the wiser for this lesson. Next time we overhauled him we made our approach in a far more gingerly manner. We kept as little way as possible on our boat, determined not to lose time again by overshooting our mark. As long as he could, our duck led us down stream, then, when we had all but caught him, he made a feint of swooping off to the right, a manoeuvre which our coxswain promptly followed. But no sooner was our rudder round than the rogue deftly brought his punt sharp to the left, and so once more escaped us. This sort of thing went on for a long time, and I was beginning to think the hunt was likely to prove a monotonous affair after all, when our coxswain suddenly called to me down the boat-- "Be ready, Adams." Then it began gradually to dawn on me our coxswain after all knew what he was about. There was a rather deep bay up near the top of the course, bounded by two prominent little headlands, and into this bay the duck, in a moment of carelessness, had ventured. It was a chance not to be let slip. A few strokes brought our cutter up to the spot, and once there, our cunning coxswain carefully kept us pointed exactly across the bay. The duck, seeing his danger, made a dash to one corner, hoping to avoid us; but he was too late, we were there before him, and before he could double and make the other corner our boat had back-watered to the spot. Thus gradually we hemmed him in closer and closer to the shore, amid the cheers of our friends, until at last it was evident to every one the punt was no longer of use. Still, he let us sidle close up to him before he abandoned his craft; then with a sudden bound he sprang overboard and disappeared from view.
