nty times with the greatest rapidity. The arms of the machine,
too, were long, so that the circle which the horses and the vessels
described was quite large, and the whole twenty revolutions made quite a
considerable ride.

After finishing their circuit and dismounting from their horses, the
boys next came to a whirling machine, which revolved vertically instead
of horizontally; that is, instead of whirling the rider round and round
near the level of the ground, it carried them up, over, and down. There
was a great wheel, which revolved on an axis, like a vertical mill
wheel. This wheel was double, and between the two circumferences the
seats of the passengers were hung in such a manner that in revolving
they swung freely, so as to keep the heads of the people always
uppermost. These seats had high backs and sides, and a sort of bar in
front for the people to take hold of, otherwise there would have been
great danger of their falling out. As it was, they were carried so
swiftly, and so high, and the seats swung to and fro so violently when
the machine was in rapid motion, that the men and girls who were in the
seats filled the ear with their screams and shouts of laughter.

Rollo and Carlos, after seeing this machine revolve, went to the
carriage to ask if they might go in it the next time.

"No," said Mr. Holiday. "I am not sure that it is safe."

So the boys went away from the carriage back under the trees again, and
walked along to see what the next exhibition might be. The carriage
moved on in the avenue a little way to keep up with them.

The boys strolled along through the crowd a little while longer, looking
for a moment, as they passed, now at the stalls for selling gingerbread
and cakes, now at a display of pictures on a long line,--the sheets
being fastened to the line by pins, like clothes upon a clothes
line,--now at a company of singers, singing upon a stage under a canopy,
and now again at a little boy, about seven or eight years old, who was
tumbling head over heels on a little carpet which he had spread on the
ground, and then carrying round his cap to the bystanders, in hopes that
some of them would give him a sou. At length their attention was
attracted by some large boys, who were engaged at a stand at a little
distance in shooting at a mark with what seemed to be small guns. These
guns, however, discharged themselves by means of a spring coiled up
within the barrel, instead of gunpowder; and the
