they are placed far out upon the branches, several close together, showing as large dense masses of sticks and twigs. Year after year the young are killed, and yet the rookery is not abandoned, nor the old birds discouraged. It is to be added that this species is not the carrion crow, like ours, though so closely resembling it in appearance. It picks up its subsistence about the fields, and is not considered an unclean bird. The British carrion crow is a much more rare species. It is a strong, fierce bird, and often attacks and kills young lambs or rabbits. What is true of the birds is true of the rabbits, and probably of the other smaller animals. The British rabbit breeds seven times a year, and usually produces eight young at a litter; while, so far as I have observed, the corresponding species in this country breeds not more than twice, producing from three to four young. The western gray rabbit is said to produce three or four broods a year of four to six young. It is calculated that in England a pair of rabbits will, in the course of four years, multiply to one million two hundred and fifty thousand. If unchecked for one season, this game would eat the farmers up. In the parks of the Duke of Hamilton, the rabbits were so numerous that I think one might have fired a gun at random with his eyes closed and knocked them over. They scampered right and left as I advanced, like leaves blown by the wind. Their cotton tails twinkled thicker than fireflies in our summer night. In the Highlands, where there were cultivated lands, and in various other parts of England and Scotland that I visited, they were more abundant than chipmunks in our beechen woods. The revenue derived from the sale of the ground game on some estates is an important item. The rabbits are slaughtered in untold numbers throughout the island. They shoot them, and hunt them with ferrets, and catch them in nets and gins and snares, and they are the principal game of the poacher, and yet the land is alive with them. Thirty million skins are used up annually in Great Britain, besides several million hare skins. The fur is used for stuffing beds, and is also made into yarn and cloth. But the Colorado beetle is our own, and it shows many of the European virtues. It is sufficiently prolific and persistent to satisfy any standard; but we cannot claim all the qualities for it till it has crossed the Atlantic and established itself on the other side.
