The Black Bear of our illustration is also a member of this class. It is a native of the wooded parts of North America. This species is timid though agile, strong and is of great endurance. Its fur is soft and even and shining black in color. It can run more swiftly than can a man and will escape in this manner if possible. Though it principally feeds on herbs, fruits and grains, it will also devour live stock of the smaller kinds and may even attack cattle. In captivity they are much better natured than the other species. “They never make hostile use of their strength in their relations with their keepers, but completely acknowledge human supremacy and present no difficulties in their training. At any rate, they fear their keeper more than he does them.” The third class is illustrated by a single species, the Sloth, or Honey Bear, also called the Aswal. It is a native of India and frequents hilly localities. It feeds upon fruits, honey and the lower animals, such as ants and the grubs of various insects. It also enjoys the comb and honey of bees. With its large and scythe-shaped claws it will destroy the strongly built homes of the white ants. In its native country the Sloth is trained by jugglers to perform many tricks and in captivity it is docile and comparatively good-natured. BIRD INCIDENTS. Wrens versus Sparrows: Some time since in the early spring, a pair of English Sparrows made up their minds to take possession of a bird house in our garden which a pair of Wrens had occupied for two previous years. Mr. and Mrs. Wren had not yet arrived, so there was none to dispute the sparrows’ right or suspend operations. All went well and the nest was nearing completion, when one bright sunny morning, the former occupants arrived on the scene and trouble at once began. They evidently resented the action of the sparrows in taking the house which they anticipated using for a summer residence. An indictment of evacuation was at once served and being met by a show of sparrow impudence, forcible expulsion was next in order.
