Chill comes, the dew rises, and twilight;--and the night side of nature. How rich and varied is that of the stream side! The fern-owls with their soft plumage and noiseless flight come out, as do the great moths and bustards. This prevalence of life at the same time is as Nature would have it--the one acting as food for the other. The beat of unseen pinions is heard above, but no object visible--some night-haunting bird flying off to its feeding ground. Through the short night summer snipe whistle and wail. Newly-arrived crakes call from the meadows, and a disturbed lapwing gets up crying from the green cornstalks. Maybe the disturber was the hare whose almost human cry now comes from the thorn fence. For it the corn sprouts have come for the last time, and soon it will be in the poacher's wallet. A loud splash comes from the water, and a great black trout has sucked down its prey. This is a large-winged night-fly. That first splash is a token of more abundant night food, and soon the reach boils. Every speckled trout is "on its feed." How we long for the pliant, sympathetic rod! Then, ye lusty trout, how would the undefinable thrill rush at intervals up our arm! But our mission to-night is not this. The herons scream, the wood-owls hoot, and--what is that other night sound? The crescent moon shows a bit of light at intervals; soon masses of cloud intervene. A faint whistle, unlike that of any bird, comes up stream, and although imperceptible the dark, still water is moved. The trout cease to rise. The whistle comes nearer, and then a rustle is heard. The osier beds are stirred, and some long dark object makes its way between the parted stems. A movement would dispel the dark shadow, and which in turn would divide the dark water and take it silently away. The otters have reconnoitered, and all is safe. They come paddling down stream, and, arriving at the pool, stop, tumble and frolic, rolling over and over, and round and round, and performing the most marvellous evolutions you could possibly conceive. They swing on the willow spray, and dash with lightning velocity at a piece of floating bark, tumble with it, wrestle with it, and go through a hundred wonderful movements. They are motionless, then begin to play, and so continue for nearly an hour, when, as if suddenly alarmed, they rush down stream to their fishing grounds, and leave us cold and benumbed. We plod through the meadow beneath the moon and stars, chilled to the marrow by the falling dew.
