Tom Sawyer at School
Tom made an honest effort to study, but he could not. He took his
place in the reading class, but he read very badly that day; then in the
geography he turned lakes into mountains, mountains into rivers, and
rivers into continents, till chaos was come again. In spelling class he
could not spell the simplest words and the medal that he had worn for
months was given to another boy.
The harder Tom tried to fasten his mind on his book, the more he
thought about different things. So at last he gave it up with a sigh. It
seemed to him that the break at noon would never come. The air was
still. It was the sleepiest of the sleepy days. The voices of twenty-five
studying pupils sounded like the murmur of bees.
Outdoors it was sunny and warm. A few birds were flying in the air.
No other living thing was visible but some cows.
With all his heart Tom wanted to get free, or else to have something
of interest to do to pass the time. He put his hand into his pocket, and
suddenly his face brightened with joy. He took out a box. In the box
there was a tick. He took the tick and put it on the desk. The happy tick
started travelling along the desk, but Tom stopped him and turned him
aside with a pin, making him follow in a new direction.
Tom’s best friend Joe Harper was sitting next to him, suffering just
as Tom had been. Now he got interested in this entertainment, too. Joe
took his pin and began to play with the tick, too. The sport became
more interesting then. In a few minutes Tom said that they would
better play with the tick in turn. 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 must leave him alone as long as I can keep him from crossing
over.”
“Ail right, go ahead.”
The tick escaped from Tom, presently, and crossed the equator. Joe
harassed him a little, and then he got away and crossed back again.
While one boy was worrying the tick with absorbing interest, the other
would look on with interest as strong, the two heads bowed over the
slate, and the two souls dead to all things else.
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 a
while before when the master came tip-toeing down the room and
stood over them. He had seen a good part of the performance before he
contributed his bit of variety to it.
(From the Adventures of Tom Sau^yer by Mark Twain)
