"I will not," I replied, as I heard Tom's step on the stairs.

The window was open, and while there was yet time, I leaped out upon the roof of the library, with the bat still in my hand. Throwing the weapon down, I stepped on the bay window, and from that dropped to the ground. Picking up the bat, I retreated to the grove which bordered the lake beyond the house. I had left the valuables in the closet, and was therefore not prepared to take my final departure.

I had advanced but a few steps before Tom and his father appeared at the window. My furious foe staid there only long enough to obtain a sight of me. A moment afterwards he rushed out at the front door, and started in pursuit of me. I doubted just then whether I had gained any advantage by transferring the battle-ground to the open air, for Tom's legs were longer than mine, though probably he had not practised running so much as I had. Taking the path near the bank of the lake, I ran with all my speed, till I came to the brook which flowed round the hill in the rear of the cottage and discharged itself into the lake. For some distance above the outlet the stream was from ten to fifteen feet wide. There was a rude foot-bridge, consisting of a single wide plank, across it, for my uncle's domain extended a short distance beyond it.

I crossed this bridge. Tom was only a few rods behind me, and a brilliant strategic idea flashed into my mind as I stepped upon the plank. As it is considered good policy for a retreating army to destroy the bridges behind it, I adopted the suggestion, and as soon as I had reached the other side of the brook, I lifted the end of the plank, and pulled it over after me. Tom rushed up to the other side just as I had completed the job. The stream was a good ten feet wide, and its banks were rather soft and slippery.

From the movements he made, I thought, at first, that he intended to leap over the brook; and I placed myself in such a position as to insure his falling into the water, if he attempted such a piece of gymnastics. Tom wore nice clothes, and he did not run the risk of soiling them by a possible accident. He paused on the brink of the stream, and feared to cross the Rubicon.

"How are you, Tom Thornton?" I exclaimed, after he had looked about him for the means of bettering his situation, and of continuing the chase.

The exertions he had made to catch me had evidently cooled him off in some measure. He was out of breath, and was apparently becoming "demoralized." He looked at me, and scowled most unamiably.

"Follow the brook up to the road, and you can get across there," I added, as he again looked about him for the means of overcoming his difficulty.

"None of your impudence, you puppy!" replied he; but his invective was tame compared with what it had been.

"If I am a puppy, Tom Thornton, perhaps you would like my bark to cross the brook with," I answered.
