"If I were rich, Frank, I would help you."

"I am sure you would, sir, for you look like a kind gentleman."

This simple tribute went to my heart. The boy felt that I was a friend, and I determined that I would be one so far as I was able.

"Still I can do something for you. I am a doctor, and if you will take me round to your house I will look at your sister and see if I can do anything for her."

The boy's eyes lighted up with joy.

"Will you be so kind, sir? I will go with you now."

"Yes, Frank, the sooner the better."

I followed him for perhaps a quarter of a mile to a poor house situated on one of the side streets leading down to the North River. The street was shabby enough, and the crowd of young children playing about showed that it was tenanted by poor families, rich in children if nothing else.

Frank stopped at one of these houses and opened the door into a dirty hall.

"We live on the top floor," he said, "if you won't mind going up."
