“I didn’t see the notice on the board,” hazarded Lancelot as a forlorn hope.

“We are always pleased to listen to excuses, and our charge is two extra cuts. That will be eight. Get over.”

And Comus indicated the chair that stood in sinister isolation in the middle of the room. Never had an article of furniture seemed more hateful in Lancelot’s eyes. Comus could well remember the time when a chair stuck in the middle of a room had seemed to him the most horrible of manufactured things.

“Lend me a piece of chalk,” he said to his brother prefect.

Lancelot ruefully recognised the truth of the chalk-line story.

Comus drew the desired line with an anxious exactitude which he would have scorned to apply to a diagram of Euclid or a map of the Russo-Persian frontier.

“Bend a little more forward,” he said to the victim, “and much tighter. Don’t trouble to look pleasant, because I can’t see your face anyway. It may sound unorthodox to say so, but this is going to hurt you much more than it will hurt me.”

There was a carefully measured pause, and then Lancelot was made vividly aware of what a good cane can be made to do in really efficient hands. At the second cut he projected himself hurriedly off the chair.

“Now I’ve lost count,” said Comus; “we shall have to begin all over again. Kindly get back into the same position. If you get down again before I’ve finished Rutley will hold you over and you’ll get a dozen.”

Lancelot got back on to the chair, and was re-arranged to the taste of his executioner. He stayed there somehow or other while Comus made eight accurate and agonisingly effective shots at the chalk line.
