Our company was evidently unwelcome, but as the friend who accompanied us was a man in authority, he was constrained to admit us.
The first sound that greeted us was a piercing outcry from the treadmill.

On going to it, we saw a youth of about eighteen hanging in the air by a strap bound to his wrist, and dangling against the wheel in such a manner that every revolution of it scraped the body from the breast to the ankles.

He had fallen off from weakness and fatigue, and was struggling and crying in the greatest distress, while the strap, which extended to a pole above and stretched his arm high above his head, held him fast.

The superintendent, in a harsh voice, ordered him to be lifted up, and his feet again placed on the wheel.

But before he had taken five steps, he again fell off, and was suspended as before.
