"Come up, boys," said the captain.
Once on the bridge the captain said: "I take pleasure in introducing my companions on our little jaunt; they are brave fellows, and are made of the right kind of stuff. I think you will hear from them if America gets into the fight."
"And America is bound to get in, for we have just learned that the first American ship has been sunk without warning," said the navigating officer, as he pressed the hands of the boys.
The captain took up the receiver, which communicated with the topmast. After listening awhile, he turned to the group and said: "The sub has disappeared."
"That will mean an interesting time for us," said the captain. "I have had the same experience, but was not fortunate enough to be armed when they attacked us. Are all the vessels from England now armed?" he asked the captain commanding the vessel.
"Yes; fore and aft. We have found that but a small percentage of armed vessels have been sunk, and those which have guns at both ends are surely doubly armed," answered the commander.
The boom of the guns had brought every passenger on deck. The officers could not conceal the real state of affairs, but there was no sign of a panic. The officers did not even take the precaution to warn the passengers that they should apply or keep the life belts close at hand.
"That is the policy I suggested from the first," said the captain. "That boat must have been three miles away, at least, and a careful gunner would come pretty close to hitting the mark at that distance, and those fellows know it."
"Then why do you think the interesting or dangerous time is now coming?" asked Alfred.
"Because the safety of the ship now depends on the ability of the observers to report the moment a periscope appears in sight. If the submarine is close enough to fire a torpedo, it is near enough to be a fine target for the gunners aboard, and, as the submarine would not be likely to attempt a shot unless it had a broadside to aim at, you can see that such a position would expose her to the fire of the guns both fore and aft," responded the captain.
