"But who is going to wear the diving-dress?"
"I am," answered Benito.
"You!" exclaimed Manoel.
"I intend to do so."
It was useless to resist.
An hour afterward the raft and all the instruments necessary for the
enterprise had drifted down to the bank where the boats were waiting.
The diving-dress is well known. By its means men can descend beneath
the waters and remain there a certain time without the action of the
lungs being in any way injured. The diver is clothed in a waterproof
suit of India rubber, and his feet are attached to leaden shoes,
which allow him to retain his upright position beneath the surface.
At the collar of the dress, and about the height of the neck, there
is fitted a collar of copper, on which is screwed a metal globe with
a glass front. In this globe the diver places his head, which he can
move about at his ease. To the globe are attached two pipes; one used
for carrying off the air ejected from the lungs, and which is unfit
for respiration, and the other in communication with a pump worked on
the raft, and bringing in the fresh air.
