Mr. Herman’s verdict on the Dipper and the Kingfisher, are the more valuable because he is the great authority, in his own country, in all that relates to pisciculture. The Dipper remains with us all the year round, especially in the Peak District in Derbyshire, and the hill-streams of North Staffordshire. It is, however, found in the British Islands, wherever there are rapid rivers or stony brooks and streams. All the Highland burns and rivers have a few pairs. In Ireland, too, it is resident in the mountainous districts, but it forsakes these often, at the approach of winter, for the mouths of tidal rivers and the salt flats of the seashore. In the valley of the Dove it remains about the stream all through the winter. The birds are clever in contriving to make so heavy a nest cling to the wall of rock or stone, where it is placed. It cocks up its short tail very much as a Wren does, and dips its head in a way, which has gained for it the quaint local name of “Betty Dowker.” As it feeds much on the larvae of the May-fly and bank-fly, and others which are destructive to the salmon spawning beds, it must be of good service to the fisher. The young birds are able to swim as soon as they leave the nest, and to chase the water insects, using both legs and wings in pursuit. The wings serve as oars. The song of the bird is begun in autumn, and it will often be heard all through the winter, but always in early spring, and fully fledged young have been found by the twenty-first of March. This is a thick-set but charming bird a little over six inches in length. Head and nape are umber-brown, tail and wing-feathers dark brown; chin, throat, and upper breast white, passing off into chestnut-brown, dark-grey and black on the belly; bill brownish-black, legs and feet brown; upper parts mottled with dark grey and brown. The beak is awl-shaped, and the sharp toes on the strong feet are long and well divided. The nest is generally placed close to a running stream, preferably near to, and even behind some little waterfall. It is a large oval ball of leaves, grass, and moss, lined with dry grass and dead leaves. The entrance is low down in the side. From four to six eggs are laid, which are glossy white at first, but become dull as the bird sits. Two broods are reared in a season. [Illustration: USEFUL. THE THRUSH.] THE THRUSH.
