Both boys were walking to the stairs landing, and Dick and the others who heard the words followed. Then of a sudden the crowd that was gathered saw Sobber catch Tom by the throat.

"Le—let go!" gasped Tom.

"Take that!" retorted the bully, and banged Tom's head against the wall.

There was a scuffle near the stairs, and both boys fell up against the railing.

"Look out, Tom!" cried Dick. "He'll throw you down the stairs!" And he tried to go to his brother's assistance. But before he could reach the spot the two contestants had separated.

"That for you!" roared Sobber, and aimed a blow for Tom's eye. Tom dodged, and then let out with his right fist. The blow landed on the bully's chin. He tottered backward, lost his balance, and pitched down the stairs.

Just as the bully went backwards, a side door of the mess hall opened and the colored waiter who carried the food to the sick lads upstairs came out. He held a trayful of dainties in his hands. Crash! came Sobber into the tray, and he and the dishes and the waiter went to the floor in a confused heap.
