What is more disturbing than the occasional rattle of a window sash when we are trying to woo sleep?  By and by Tom discovered it was that which had played the mischief with his rest.  He sprang impatiently out of bed, and hurried to the window, with the intention of righting matters.

The bright moon shining from an unclouded sky made it almost as light as day.  He stood a minute, looking out upon the beautiful scene; for, young as he was, he could not fail to be impressed by the striking loveliness of everything out-doors.

“I wonder whether they’ve catched Tippo Sahib”—­

The lad caught his breath, for just then he saw something moving in the shadow of the woodshed.  A second look showed it to be some sort of quadruped, and the third—­could he believe his eyes?—­revealed the tiger himself!

Yes, it was the terrible brute and no mistake.  The boy rubbed his eyes and looked again.  Some unaccountable attraction seemed to have brought Tippo Sahib back to the dwelling where he had met with so interesting an experience that afternoon.

But all this being so, Tom Gordon might well ask himself what good the presence of the animal promised to be to him.  Hitherto, he and his friends had counted themselves lucky in being able to keep out of his way when he showed a desire to explore the interior of the house.  How, then, could he expect to get the hundred dollars offered for the capture of the brute?

Mingled with the eager wish of the lad to earn the munificent sum, was a slight misgiving as to the meaning of this return of the tiger.  Having eluded the men sent after him, had he come back to revenge himself upon those who had treated him so ill?

This discomforting thought was dissipated by the action of Tippo Sahib.  He did not move around as on his former visit, but seemed to be prowling about the woodshed, as if in quest of something.  Surely he would not act thus if he meditated an attack upon the inmates of the home!

But Tom had learned from his aunt and mother that if the tiger chose, he could readily leap from the ground to the windows of the upper story, and, therefore, would have little difficulty in entering, if he was bent on doing so.

“I’ll get my gun, so as to be ready to shoot him.  But if I shoot him, I won’t get the reward that was promised; but it’s better to kill him than to have him chaw us to pieces.”

Just then the animal worked his way round the corner of the structure, out of the shadow, into the bright moonlight.  He showed no interest in the house itself, but confined his attention to the woodshed,—­a fact which lessened the lad’s fear, and held him at the window, closely watching the beast.

His change of location brought him to the front of the strong wooden building, and near the partially open door.

The heart of the lad gave a great bound.

“S’pose he goes inside, and I slip up and shut him in!”
