But one day Tommy stumbled upon Spot quite by accident. There was no
wind at all that day, to bring any scent to Tommy's sharp nose. And he
suddenly found that Spot was right in front of him, between him and
the river.

Tommy Fox turned and ran. He laughed, too; because he felt quite sure
that he could outwit old Spot. And he leaped and twisted and turned
about, and made so many circles, that he felt sure Spot couldn't
follow him.

Yes--Tommy felt so safe that he stopped running and was trotting
slowly along through the field in which he lived. He was almost home,
when he heard a noise behind him. He looked around and to his great
surprise there was Spot almost upon him.

There was no time to lose. There was only one thing Tommy could do.
The door of his mother's house was only a short distance off and Tommy
made for it. Luckily, he managed to reach it. Once inside, he could
hear the dog Spot barking in the opening. But he knew that Spot was
too big to follow him.

Although Tommy was very glad to be safe at home, he was worried. For
now Spot know where he and his mother lived; and they would have to
move. Tommy was afraid his mother would be very angry with him for
being so stupid as to let Spot follow him. But he couldn't help it
now.

Meanwhile, old Spot continued to bark, and scratch at the door of
Tommy's home. But at last he stopped. And all was still.
