of the wild turkey from North America, which has partly succeeded. Beavers, too, have been induced to resume possession of their ancient streams under careful supervision, but they are outside present consideration. While England has thus lost some species and suffered a diminution of several, other countries have been supplied from our streams and woods and hedge-rows. England has sent the sparrow to the United States and Australia; also the nightingale, rabbit, salmon, trout, and sweet-briar.
It is quite open to argument that pheasant-covers have saved as well as destroyed. Wood-pigeons could scarcely exist in such numbers without the quiet of preserved woods to breed in; nor could squirrels. Nor can the rarity of such birds as the little bearded tit be charged on game. The great bustard, the crane, and bittern have been driven away by cultivation. The crane, possibly, has deserted us wilfully; since civilization in other countries has not destroyed it. And then the fashion of making natural history collections has much extended of recent years: so much so that many blame too ardent collectors for the increasing rarity of birds like the crossbill, waxwing, hoopoe, golden oriole, and others which seem to have once visited this country more commonly than at present.
