ou know."

So Sunny Boy, very reluctantly, thanked the man in charge of the boats
and walked down the aisle to see the mechanical trains.

Goodness! the trains were more fascinating than the boats. There were
miles and miles of track, and little colored signal lights, and
stations and tunnels and freight and coal and passenger trains, with
freight and coal and passengers to go in them.

"All running!" marveled Sunny Boy. "Just like Christmas!"

Mrs. Horton was trying to pull him past this absorbing counter, for
they really had a great deal more to see and the time was getting
short, when Sunny gave a shout.

"Mother, look! There's a runaway engine! Whee, a wreck!"

Sure enough, an engine with no cars attached was coming rapidly down
grade toward a passenger train stopped at one of the stations. Sunny
Boy's voice had drawn a number of the shoppers, and a small crowd
gathered to see what would happen. The clerk had left the counter and
gone out to an aisle table to have a floor-man sign his book, and

come up."

the clerk lifted him up on the largest one, and very high from the
ground Sunny felt.

But it was the tin automobile that captured his heart.

"Oh, Mother!" he said when he found it, "it's just like our car, two
lamps and all."

"It is pretty nice," admitted Mrs. Horton. "We'll have to see what
Daddy says about one when we go home. You are getting too old for the
kiddie car, aren't you? How does this one run, dear?"

Sunny Boy showed her, and explained how the brakes worked, and they
had an interesting half-hour comparing the different kinds of cars and
learning how much they cost. Then Mother discovered that it was time
to go back to the hotel if they were to meet Daddy promptly.

"I could stay here," suggested Sunny Boy, his arm about a stuf
