"It is something I should like to see." They found it on the south side of Midway Plaisance in a small building surrounding a huge tank of water.

On the balcony of its second story stood a man turning a force-pump, which seemed to attract a good deal of attention from the passers-by.
Each visitor paid ten cents at the door, then passed up a rude stairway by which he reached the surface of the water.

There a lecturer was seated, who explained how the air was made to enter the diver's armor, and how to leave it.

Then people were invited to throw small coins into the water.
Captain Raymond put a bright dime into the hand of each of his younger children and they gleefully tossed them in.

The diver was in the bubbling water, they could not see him, but presently, through a telephone, he gave the dates on the coins.
