uch easier than if we were on deck," answered the captain.
"Why do you think so?" asked Alfred.
"Because water is a better conductor of sound than air," was the reply.
"Do you mean that we can hear it better than if the sound came through
the air?" queried Alfred.
"The sound can be heard not only much plainer, but also much sooner than
through the air," answered the captain.
"I think we are going down again," remarked Ralph.
"No doubt of it," answered the captain quietly.
"Do you think they have hit us?" eagerly inquired Ralph.
The captain did not reply. Alfred reached his hand forward and grasped
the captain's hand. "You needn't fear to tell us if you think we are
going down for the last time."
"You are a brave boy!" said the captain. "I do not know what to answer.
I have never been on a submarine when it was struck by a bullet; but it
seemed to me as though something struck our shell, and if it did there
is no help for us, for the devils would gloat on our misery, and would
not think of liberating us, to give us a chance for our lives."
Fifteen minutes elapsed before the captain continued: "This gives me
some hope."
"What is it?" quickly inquired Ralph.
"We are still on an even keel," was the answer.
"Does that mean that we are safe?" asked Alfred.
"Yes, if the shell of the submarine had been pierced, and we were really
going down it would not be long before the hull would lose its equipoise
and turn around, or it might stand on end, due to the distribution of
water throughout the interior," was the reply.
"I understand now," said Alfred. "You think we are still floating, but
do you think we are on the surface?"
"We are, undoubtedly, submerged, for it is evident that the smooth
motion of the propeller comes from the electric motors and not from the
internal combustion engines, which are used solely while running on the
surface," remarked the captain.
After hours more of interminable waiting, they heard a noise close at
hand. With something like a snap the door opened and a flood of light
streamed into their compartment from the electric bulbs without, and,
looking up, they saw, at the ceiling of their room, a small electric
bulb.
"Why is it we didn't hunt for that?" whispered Ralph, looking up.
"But I can't see any way to turn it on," said Alfred.
"That lights only from the outside," said the attendant. "Here is
something to eat," he continued in English.
"What time is it
