"Indeed, and travel home," said the man, "and quit Paris without having seen the most wonderful thing of all—the real wonder of the present period, created by the power and resolution of one man!"

"I will not go down for all that," was the reply.

"The wonder of the present time," it had been called. The Dryad had heard and had understood it. The goal of her ardent longing had thus been reached, and here was the entrance to it. Down into the depths below Paris? She had not thought of such a thing; but now she heard it said, and saw the strangers descending, and went after them.

The staircase was of cast iron, spiral, broad and easy. Below there burned a lamp, and farther down, another. They stood in a labyrinth of endless halls and arched passages, all communicating with each other. All the streets and lanes of Paris were to be seen here again, as in a dim reflection. The names were painted up; and every house above had its number down here also, and struck its roots under the macadamized quays of a broad canal, in which the muddy water flowed onward. Over it the fresh streaming water was carried on arches; and quite at the top hung the tangled net of gas-pipes and telegraph-wires.

In the distance lamps gleamed, like a reflection from the world-city above. Every now and then a dull rumbling was heard. This came from the heavy wagons rolling over the entrance bridges.

Whither had the Dryad come?

You have, no doubt, heard of the CATACOMBS? Now they are vanishing points in that new underground world—that wonder of the present day—the sewers of Paris. The Dryad was there, and not in the world's Exhibition in the Champ de Mars.

She heard exclamations of wonder and admiration.

"From here go forth health and life for thousands upon thousands up yonder! Our time is the time of progress, with its manifold blessings."

Such was the opinion and the speech of men; but not of those creatures who had been born here, and who built and dwelt here—of the rats, namely, who were squeaking to one another in the clefts of a crumbling wall, quite plainly, and in a way the Dryad understood well.
