An amusing incident, demonstrating animal sagacity. The servant is dusting the clothes of her master from the fire-escape and unfortunately drops the coat. A rag-picker passing quickly appropriates the coat. When the maid appears on the street she is unable to find the garment, and accosts the rag-picker, who denies all knowledge concerning it. She promptly returns to the house and unfastening the dog starts him on the trail, with the result that he traces the coat to the rag-picker’s bag, which he grasps and holds onto with a ferocious grip until officers secure the man.
