In former days, the Spanish wolves congregated in large packs in the passes of the Pyrennees; and even now the _lobo_ will follow a string of mules, as soon as it becomes dusk, keeping parallel with them as they proceed, leaping from bush and rock, waiting his opportunity to select a victim. Black wolves also are found in the mountains of Friuli and Cattaro; the Vekvoturian wolf of Siberia, described by Pallas, is one of the darkest variety. In Persia and in India wolves are trained and made to play tricks and antics as monkeys and dogs are in Europe. At Teheran, Bankok, and Arracan, a well-trained wolf that can dance a polka of the country, sing a national air, and preserve a grave face during five minutes, with a pair of spectacles on his nose, will fetch as much as 500 dollars. "In China," remarks Colonel Smith, "wolves abound in the northern province of Shantung;" and Buffon, quoting from Adanson, asserts, that "there is a powerful species of the wolf in Bengal, which hunt in packs, in company with the lion." "One night," says Adanson, "a lion and a wolf entered the court of the house in which I slept, and unperceived, carried off my provisions; in the morning my hosts were quite satisfied, from the well-marked and well-known impressions of their feet in the sand, that the animals had come together to forage." Colonel Smith observes, that "the French wolves are generally browner and somewhat stronger than those of Germany, with an appearance far more wild and savage: the Russian are larger, and seem more bulky and formidable, from the great quantity of long coarse hair that cover them on the neck and cheeks."
