And then something
happened.

The other dog, who it appeared had been growling at Snap all the while
the two were in the car, now made a rush to get at him. Perhaps he only
wanted to make friends, but it looked as though he wanted to bite. Snap
did not like this so he barked at the other dog. Then the other dog
became frightened and ran away, pulling loose from his master.

Straight toward Dinah, who was carrying Snoop in the basket, ran the
other dog. His master called him to come back but he would not. Then
Snap, seeing his enemy run, naturally ran after him, pulling the chain
out of Bert's hand.

"Go 'way! Go 'way!" cried Dinah. But the strange dog ran right into her,
upsetting her. Down she fell. The basket slipped from her arm, and the
cover flew off, letting out Snoop. The black cat, seeing a strange dog,
ran down the platform as fast as she could. So with Snap chasing the
other dog, and with the Bobbsey twins yelling, and with men and boys
shouting, there was so much excitement that Mr. and Mrs. Bobbsey did not
know what to do.

CHAPTER IV

HOME AGAIN

"Come back, Snap!" cried Bert. "Come back!"

"Run after him," begged Nan.

"I'll get Snoop!" shouted Freddie.

"And I'll help you," offered Flossie, hurrying along as fast as her fat
little legs would take her. Freddie was already half-way down the
platform after the black cat.

"Come back, children! Come back!" begged Mother Bobbsey. "Oh, Richard!"
she called to her husband, "get the children!"

"All right," he answered, but he could hardly keep from laughing, it was
all so funny. Dinah still sat where she had fallen, after being knocked
over by the strange dog, and there was a look of wonder on her face, as
if she did not quite understand how it had all happened.

"I beg your pardon. I'm sure I'm very sorry for what has happened,"
said the man whose dog had caused all the trouble by rushing at Snap.

"Oh, you couldn't help it," returned Mrs. Bobbsey. "Richard," she again
called to her husband, "do look after Flossie and Freddie. I'm afraid
they'll be hurt."

"I'll help get them, and the cat too!" offered Tommy Todd. "I like cats
and dogs," he added, and, carefully setting down the basket of flowers,
he, too, ran down the platform.

By this time Snap, chasing after the strange dog, was half-way across
the street in front of the railroad station, but Snoop, the black cat,
was not in sight. Flossie and Freddie, having come to the end of
