Quotation by Henry David Thoreau

The morning was a bright one, and perfectly still and serene, the lake as smooth as glass, we making the only ripple as we paddled into it. The dark mountains about it were seen through a glaucous mist, and the brilliant white stems of canoe birches mingled with the other woods around it. The wood thrush sang on the distant shore, and the laugh of some loons, sporting in a concealed western bay, as if inspired by the morning, came distinct over the lake to us, and, what was more remarkable, the echo which ran round the lake was much louder than the original note; probably because, the loon being in a regularly curving bay under the mountain, we were exactly in the focus of many echoes, the sound being reflected like light from a concave mirror.
