Retracing his steps quickly, Mr. Finbrink halted in front of his house, scanning the windows. Not a crack in a window pane could he discern, which was not remarkable, in view of the fact that no panes of glass had been broken.

"I need a lantern," Mr. Finbrink said to himself, and went inside the house. Soon afterwards he came out with a lighted lantern, and began his inspection. Three windows showed no sign of damage. Nor did the fourth. Then Mr. Finbrink chanced to glance down at the ground. There rested the brick, the fragments of the broken bottle lying around it.

"Say, what's that? What's that?" ejaculated Mr. Finbrink, much puzzled. Soon, however, he began to see light on the riddle. His lips parted in a grin; the grin became a chuckle.

"Humph! That goes ahead of anything I ever had the brains to think up when I was a boy," laughed the man. "That's a good one! It sounded for all the world as though someone had smashed one of my windows with a brick-bat. Ha, ha, ha! That's an all right one! I'd be willing to shake hands with the boy who put up that joke on me. How about my own Timmy, I wonder? No; Timmy wouldn't be smart enough for this one—-but he may have smart friends. I'll look up that young hopeful of mine!"

With that purpose in view, the lantern still in his hand, Mr. Finbrink passed into the house and then up the back stairs. On the next floor he pushed open the door of a room, holding the lantern high as he scanned the bed.

There lay Master Timmy, covered only with a sheet, his head sunk in the depths of a pillow, eyes tightly closed, and breathing with almost mechanical rhythm.

"Oh, you're asleep, aren't you?" demanded his father, in a low, ironical voice. "How long have you been asleep, Tim?"

But Timmy's only answer was the beginning of a snore.

"Are you very tired, Timmy?" continued his father craftily.

Still no answer.
