Anyhow, he could _imagine_ that Bully Harberth was the Snake or Its emissary and, since he was indirectly brought upon him by the Snake, regard him as a myrmidon--and deal with him accordingly....
"How do you like this ?" inquired that young gentleman as he suddenly seized the seated and unsuspecting Dam by the head, crushed him down with his superior weight and dug cruelly into the sides of his neck, below the ears, with his powerful thumb and fingers.

"It is called 'grippers'.

You'll begin to enjoy it in a minute." ...

In a few seconds the pain became acute and after a couple of minutes, excruciating.
Dam kept absolutely still and perfectly silent.
To Harberth this was disappointing and after a time he grew tired.
Releasing his impassive victim he arose preparatory to introducing the next item of his programme of tortures.
"How do you like _this_ ?" inquired Dam rising also--and he smote his tormentor with all his strength beneath the point of his chin.

Rage, pain, rebellion, and undying hatred (of the Snake) lent such force to the skilful blow--behind which was the weight and upward spring of his body--that Bully Harberth went down like a nine-pin, his big head striking the sharp edge of a desk with great violence.
He lay still and white with closed eyes.
