Let us go back again to the bank by the cornfields, with the glorious open stretch of stream. In the evening, the rosy or golden hues of the sunset will be reflected on the surface from the clouds; then the bats wheel to and fro, and once now and then a nighthawk will throw himself through the air with uncertain flight, his motions scarcely to be followed, as darkness falls. Am I mistaken, or are kingfishers less numerous than they were only a few seasons since? Then I saw them, now I do not. Long-continued and severe frosts are very fatal to these birds; they die on the perch. And may I say a word for the Thames otter? The list of really wild animals now existing in the home counties is so very, very short, that the extermination of one of them seems a serious loss. Every effort is made to exterminate the otter. No sooner does one venture down the river than traps, gins, nets, dogs, prongs, brickbats, every species of missile, all the artillery of vulgar destruction, are brought against its devoted head. Unless my memory serves me wrong, one of these creatures caught in a trap not long since was hammered to death with a shovel or a pitchfork. Now the river fox is, we know, extremely destructive to fish, but what are a basketful of "bait" compared to one otter? The latter will certainly never be numerous, for the moment they become so, otter-hounds would be employed, and then we should see some sport. Londoners, I think, scarcely recognise the fact that the otter is one of the last links between the wild past of ancient England and the present days of high civilisation. The beaver is gone, but the otter remains, and comes so near the mighty City as just the other side of the well-known Lock, the portal through which a thousand boats at holiday time convey men and women to breathe pure air. The porpoise, and even the seal, it is said, ventures to Westminster sometimes; the otter to Kingston. Thus, the sea sends its denizens past the vast multitude that surges over the City bridges, and the last link with the olden time, the otter, still endeavours to live near. Perhaps the river is sweetest to look on in spring time or early summer. Seen from a distance the water seems at first sight, when the broad stream fills the vision as a whole, to flow with smooth, even current between meadow and cornfield. But, coming to the brink, that silvery surface now appears exquisitely chased with ever-changing lines. The light airs, wandering to and fro where high banks exclude the direct influence of the breeze, flutter the ripples hither and thither, so that, instead of rolling upon one lee shore, they meet and expend their little force upon each other. A continuous rising and falling, without a line of direction, thus breaks up the light, not with sparkle or glitter, but with endless silvery facets.
