One morning, looking very gently over the parapet of the bridge (down stream) into the shadowy depth beneath, just as my eyes began to see the bottom, something like a short thick dark stick drifted out from the arch, somewhat sideways. Instead of proceeding with the current, it had hardly cleared the arch when it took a position parallel to the flowing water and brought up. It was thickest at the end that faced the stream; at the other there was a slight motion as if caused by the current against a flexible membrane, as it sways a flag. Gazing down intently into the shadow the colour of the sides of the fish appeared at first not exactly uniform, and presently these indistinct differences resolved themselves into spots. It was a trout, perhaps a pound and a half in weight. His position was at the side of the arch, out of the rush of the current, and almost behind the pier, but where he could see anything that came floating along under the culvert. Immediately above him but not over was the mass of weeds tangled in the dead branch. Thus in the shadow of the bridge and in the darkness under the weeds he might easily have escaped notice. He was, too, extremely wary. The slightest motion was enough to send him instantly under the arch; his cover was but a foot distant, and a trout shoots twelve inches in a fraction of time. The summer advanced, the hay was carted, and the wheat ripened. Already here and there the reapers had cut portions of the more forward corn. As I sat from time to time under the aspen, within hearing of the murmuring water, the thought did rise occasionally that it was a pity to leave the trout there till some one blundered into the knowledge of his existence. There were ways and means by which he could be withdrawn without any noise or publicity. But, then, what would be the pleasure of securing him, the fleeting pleasure of an hour, compared to the delight of seeing him almost day by day? I watched him for many weeks, taking great precautions that no one should observe how continually I looked over into the water there. Sometimes after a glance I stood with my back to the wall as if regarding an object on the other side. If any one was following me, or appeared likely to peer over the parapet, I carelessly struck the top of the wall with my stick in such a manner that it should project, an action sufficient to send the fish under the arch. Or I raised my hat as if heated, and swung it so that it should alarm him. If the coast was clear when I had looked at him still I never left without sending him under the arch in order to increase his alertness. It was a relief to know that so many persons who went by wore tall hats, a safeguard against their seeing anything, for if they approached the shadow of the tall hat reached out beyond the shadow of the parapet, and was enough to alarm him before they could look over. So the summer passed, and, though never free from apprehensions, to my great pleasure without discovery.
