was worth while. Finally they moved on in disgust, after paying the
man about a dollar apiece.

On a corner were a group of little burros, the tiny Mexican donkeys and
children could ride along to the corner and back for ten cents. Nothing
in the whole world could make those donkeys go off a slow walk. They
knew perfectly well that it didn't pay to frisk up their heels and bolt,
so they simply wagged an ear or flirted a tail if the children slapped
them.

"I suppose they have traveled to that corner fifty million times," said
Helen, watching the solemn procession take its way with the donkey boys
following close on the donkeys' heels and shouting to them to "Giddap!"

"Poor dears!" said Rosanna. "How tired of it all they must be!"

It took a lot of argument before they decided to try the Ferris wheel,
but Rosanna wisely said that it would probably be the last chance _she_
would ever have to try it, and Helen said that she wouldn't want to come
unless Rosanna could, so the children seated themselves and were
strapped in the basket, and presently when all the little basket seats
were full, off they went. It was perfectly frightful when you have just
been a simple human being all your life and suddenly try sailing up and
around all at the same time! At the top there was a drop, a sort of
launching out right into space, and the girls clung to each other and
shut their eyes.

After they had rested awhile they went along, threading their way
through the crowds until they came to the roller coaster.

Here they sat in a little car which held four people, but Mrs. Culver
still refused to leave the ground. They embarked from a little platform,
and were in one car of a little train of four. On the other side of the
platform four other cars were filling up. When all the seats were taken,
someone gave a signal and off went the little trains down such a steep
grade that their rush carried them far up another incline. This was
repeated over and over until they had reached a great height. Here there
was a sheer drop as straight as it could be made without taking the cars
off the rails, and down they went, turning and twisting. All at once
they were plunged into a pitch black tunnel.

"Oh, oh, _oh_!" cried Rosanna. It was the first time she had screamed,
but she did not hear herself because everyone else was screaming too.

Then as suddenly as they had plunged into the dark, they came out into
the light again, gave a few more tu
