"What'll we do then?"
Bob thought a few seconds.
"I'll tell you," he said. "We'll put a tic-tac on Mrs. Mooney's window. She lives all alone, and she'll think it's a ghost rapping."
"Good! Come on. Have you got some string?"
"Sure."
So you see how poorly Bob remembered his promise of the night before, and with what thoughtlessness he again started to indulge in a prank—a prank which might throw a nervous woman into hysterics. Yet in this Bob was just like thousands of other boys—he "didn't mean anything." The trouble was he did not think.
So the two boys, their heads full of the project of making a tic-tac, stole quietly through the village streets toward the cottage of the Widow Mooney.
CHAPTER III
A STRANGE PROPOSITION
Perhaps some of my readers may not know what the contrivance known as a "tic-tac" is like. Those of you who have made them, of course, do not need to be told. If you ever put them on any person's window, I hope you selected a house where there were only boys and girls or young people to be startled by the tic-tac. It is no joke, though at first it may seem like one, to scare an old person with the affair. So if any boy or girl makes a tic-tac after the description given here, I trust he or she will be careful on whom the prank is played.
