Intelligent Dogs.
Some time ago I had occasion to speak of a wise cat of Colonel Stuart Wortley's. Now I may mention the doings of two intelligent dogs of his. One of them was able to tell whether or not it might go out with the housekeeper, according as she wore a hat or bonnet. If she wore her hat it knew that it might accompany her, and barked with joy as soon as she appeared, but if she wore her bonnet it knew she was going to church or on a visit, and that it could not go with her. It became so familiar with these articles that if drawings of hat and bonnet were placed before it, it could indicate which was which. The other dog was a Skye terrier. When the Colonel went out it was enough to say "Yes" or "No" in an ordinary tone for the dog to know whether it might accompany him or not. The terrier was next taught to distinguish the words when printed on cards—Yes and No—and in a few weeks it never mistook them.
