Sue. "Get up,
please, I want to ask you boys something."

Hearing this, and seeing that Mrs. Brown was well dressed and was a
"white lady of quality" carrying a pocketbook out of which pennies might
be handed, the fighting boys stopped. The top one got off the other, and
both stood up, dusting off their ragged clothes. Neither seemed much
hurt, and both were broadly grinning.

"You mustn't fight!" declared Mrs. Brown.

"Oh, we was only in fun, lady," laughed the one who had first tripped
the other.

"Have you seen a little boy and girl?" went on Mrs. Brown.

"White chilluns?" asked one of the black boys.

"Co'se she done mean white chilluns!" exclaimed another. "I done seen
'em get offen de train!"

"Have you seen them since?" asked Mrs. Brown. "We had lunch, and my
husband went uptown. I sat down on the bench, and Bunny and Sue walked
down the street. I haven't seen them since, and they aren't in sight. Do
you know where they are?"

None of the colored boys did, it appeared, though hearing that two white
children were missing there were soon eager volunteers to search for
them.

Out and around the station scattered the colored boys, Mrs. Brown having
said she would give fifty cents to the one first bringing news of Bunny
and Sue.

"Oh, golly! I'se gwine to earn dat money, suah!" cried one lad.

But though the boys looked up and down the different streets, and though
some even went into near-by stores, not a trace of Bunny or Sue could
they find. And for a good reason--because Bunny and Sue were traveling
far away in the freight car with Nutty, the tramp.

Mrs. Brown became more and more worried as nearly an hour passed and
Bunny and Sue were not found. The station agent came back, for it was
nearly time for the other train to arrive. But he could tell nothing of
the missing children.

"I must find my husband!" Mrs. Brown exclaimed, and she was just
starting uptown when Mr. Brown came riding to the station in an
automobile. One of the business men, on whom he had called, had brought
him back in the car.

"Oh, Walter," cried Mrs. Brown, "Bunny and Sue are lost! I can't find
them anywhere! What shall we do?"

CHAPTER XVIII

THE TRICK DOG

We left Bunny and Sue Brown standing beside the track with the jolly
switchman, who laughed at the little girl's question as to whether his
wife lived in the small brown shanty.

"My wife live in that little shanty?" he cried, his face all wrinkled
with
