The Hippodrome is a long, oval enclosure, with eight or ten ranges of seats extending all around it, and rising one above another, like the seats of the Coliseum at Rome. There is a roof extending all around over the seats; but the area within is so large that it could not well be covered with a roof. Besides, if there were a roof over it, how could the balloons go up?

Then, moreover, the spectacles which are exhibited in the Hippodrome appear to much better advantage when seen in the open light of day than if they were under the cover of a roof, so long as the spectators themselves are protected from the sun and from any sudden showers.

The area in the middle of the Hippodrome is about one hundred yards long and fifty yards wide. It is so large that there is room for a good wide road all around it, and also for another road up and down the middle, with little gardens of grass and flowers between. At the very centre is a round area, where there is a concealed canal of water to represent a stream. This water is ordinarily covered with planks, and the planks are covered with a very thick canvas carpet, and this with sand; so that the water is entirely concealed, and the horsemen ride over it just as they do over any other part of the area. When they wish to use it, to show how the horses could leap over streams, they take off the sand, roll up the carpet, and carry away the planks; and there they have a very good representation of a stream.

The performances at the Hippodrome are very various. Sometimes whole troops of horse come in from between two great curtains at one end, all elegantly caparisoned and mounted, some by men and some by girls, but all, whether men or girls, dressed in splendid uniforms. These troops ride round and round the area, and up and down in the middle of it, performing a great variety of evolutions in the most rapid and surprising manner.

Then there are races of various kinds. Some are run by beautiful girls, who come out mounted on elegant gray horses that are mottled like leopards, each of the riders having a scarf over her shoulders of a different color from the rest, so that they may be all readily distinguished from each other in the race. Then there are races of chariots, three running at a time, round and round the area; and of small ponies, with monkeys on them for riders. There are various contrivances, too, for athletic and gymnastic feats, such as masts and poles for climbers to ascend, and other similar apparatus. All these things give the interior of the Hippodrome quite a gay and lively appearance, and the area necessary for them is so large that the ranges of seats surrounding it are sufficient to accommodate ten thousand spectators.

It was to this place that Adrienne and Antoine, with their father and mother, were going, while Rollo and Jennie supposed that they were going to a church. There was nothing to lead Rollo to suspect his mistake in the aspect of the building as he approached the entrance to it; for the sides of it were hidden by trees and other buildings, and the portal, though very large and very gayly decorated, seemed still, so far as Rollo could get a glimpse of it through the crowds of people, only to denote that it was the entrance to some very splendid public edifice, without at all indicating the nature of the purposes to which it was devoted.

The immense concourse of people which were pouring into the Hippodrome divided themselves at the gates into two portions, and passed up an ascent to enter at side doors. Rollo and Jane, following their guides, went toward the right. They observed that the father of Adrienne and Antoine stopped at a little window near the entrance, to pay the price of admission for himself and wife and his two children and to get the tickets. He paid full price for his two children, and so took four full tickets. Rollo and Jane did not see him pay the money. They only observed that there was a crowd at the little window, and they saw Antoine's father take the tickets. They did not know what this meant, however; but they followed on. When they all came to the doorway which led up to the ranges of seats, the man whose duty it was to take the tickets supposed that the four children all belonged to the same family, and that they had been admitted at half price, and that, accordingly, two of the tickets were for the father and mother, and the other two for the four children. So he let them all pass on together, especially as there was, at that time, such a throng of people crowding in that there was no time to stop and make any inquiries.

Rollo and Jane were carried along by the current up a flight of stairs, which came out among the ranges of seats; and after moving along for some distance till they came to a vacancy they sat down, and began to look around and survey the spacious and splendid interior into which they had entered. They were at once overwhelmed with the magnificence of the spectacle which was presented to view. Instead of a church, they found a vast open area extended before them, surrounded with long ranges of seats, and laid out in the interior in the most graceful and beautiful manner.

"Jennie," said Rollo, after gazing about for some moments, almost bewildered, "if this is any kind of meeting at all, I think it must be a camp meeting."

Jennie was completely bewildered, and had no opinion on the subject whatever; so she said nothing.
