nd neither getting the fullest benefit of
the tick. So he put Joe's slate on the desk and drew a line down the
middle of it from top to bottom.

"Now," said he, "as long as he is on your side you can stir him up and
I'll let him alone; but if you let him get away and get on my side,
you're to leave him alone as long as I can keep him from crossing over."

"All right, go ahead; start him up."

The tick escaped from Tom, presently, and crossed the equator. Joe
harassed him awhile, and then he got away and crossed back again. This
change of base occurred often. While one boy was worrying the tick with
absorbing interest, the other would look on with interest as strong,
the two heads bowed together over the slate, and the two souls dead to
all things else. At last luck seemed to settle and abide with Joe. The
tick tried this, that, and the other course, and got as excited and as
anxious as the boys themselves, but time and again just as he would
have victory in his very grasp, so to speak, and Tom's fingers would be
twitching to begin, Joe's pin would deftly head him off, and keep
possession. At last Tom could stand it no longer. The temptation was
too strong. So he reached out and lent a hand with his pin. Joe was
angry in a moment. Said he:

"Tom, you let him alone."

"I only just want to stir him up a little, Joe."

"No, sir, it ain't fair; you just let him alone."

"Blame it, I ain't going to stir him much."

"Let him alone, I tell you."

"I won't!"

"You shall--he's on my side of the line."

"Look here, Joe Harper, whose is that tick?"

"I don't care whose tick he is--he's on my side of the line, and you
sha'n't touch him."

"Well, I'll just bet I will, though. He's my tick and I'll do what I
blame please with him, or die!"

A tremendous whack came down on Tom's shoulders, and its duplicate on
Joe's; and for the space of two minutes the dust continued to fly from
the two jackets and the whole school to enjoy it. The boys had been too
absorbed to notice the hush that had stolen upon the school awhile
before when the master came tiptoeing down the room and stood over
them. He had contemplated a good part of the performance before he
contributed his bit of variety to it.

When school broke up at noon, Tom flew to Becky Thatcher, and
whispered in her ear:

"Put on your bonnet and let on you're going home; and when you get to
the corner, give the rest of 'em the slip, and turn down through the
lane and
