Ferris struck the boy in the mouth, and the little fellow let out a yell.
Hal was just about to dart to his assistance when a policeman came along and touched Ferris on the shoulder.
"What's the trouble here?" he demanded.
Ferris turned savagely, but his manner changed when he beheld the officer of the law.
"This chap is a rascal," he explained.
"In what way?"
"He fired a snow-ball at me and hit me in the ear."
"I didn't," howled the urchin. "It was anudder fellow wot fired dat snow-ball."
And he began to cry bitterly.
"It was only done in fun, I suppose," said the officer.
