A DOG STORY.

A London dog story is apt to be a hard sort of a tale to believe, but it is never lacking in interest. The latest is of a dog who takes a daily walk with its mistress. The animal has observed that at a certain crossing the policeman stops the traffic to allow his mistress to pass over. The other day the dog went out alone, and when he came to the crossing he barked to attract the policeman's attention. The policeman observed what the dog wanted. He stopped the traffic, and the dog walked solemnly across.
