"Tackle der bag a while, an' let's see how yer work." Browning went at the punching bag while the professor stood by and called the changes.

He thumped it up against the ceiling and caught it on the rebound thirty times in succession, first with his right and then with his left.

Then he went at it with both hands and fairly made it hum.

Then, at the word, with remarkable swiftness, he gave it fist and elbow, first right and then left.

Then he did some fancy work at a combination hit and butt.
By the time Buster called him off Browning was streaming with perspiration and breathing heavily.
"Dat's first rate," complimented the professor.
