The Boy Volunteers with the Submarine Fleet Part 9

"Why wouldn't it take longer to travel 1,400 miles?" asked Ralph.

"Because on the long route we would be able to travel four-fifths of the way on the surface, and would not have to avoid mines and nets. The Channel route is a dangerous one, requiring the utmost caution," said the captain.

The second morning Alfred was outside, as usual, consulting the instruments, when a voice remarked in response to an inquiry: "48, 10."

He paid no attention to it at the time, but later on, in a conversation, remarked to the captain:

"Some one in the conning tower, this morning, said '48, 10.' What do you suppose he meant by that?"

"Glad you remembered that. Are you sure the figures you give are correct?" asked the captain eagerly.

"Sure of it," was Alfred's reply.

"Then we are near the English Channel. Good; I am glad to know that. Did you hear them refer to any other figures?" asked the captain.

"What would the other figures be?" asked Ralph.

"Of course, I can only guess. The figures you have given me unquestionably represent forty-eight degrees and ten minutes north lat.i.tude. What interests me most is to get our position east and west,"

said the captain.

"About what longitude are we in?" asked Ralph.

"If we are less than five degrees west we must be in the English Channel, and it would appear that they are taking the shortest route. If we should be seven or eight degrees west I should regard it as a pretty sure symptom that we are going to encircle the British Isles," remarked the captain.

Late that afternoon Ralph rushed into their little cabin and said:

"I have an idea that I can tell you the direction we are going."

"Have you heard anything?" asked the captain.

"Not a word," answered Ralph. "I have just made an observation," he continued, laughing.

"That's good," responded the captain. "I think we are sailing north by west."

"You are wrong," replied Ralph; "we are going due east."

"Are you sure?" asked the captain, exhibiting unusual interest in the news. "How did you find it out?"

"I saw the sun," said Ralph with a chuckle.

"How and where did you see it?" asked Alfred, incredulously.

"Well, I didn't exactly see the sun, but I saw a streak that came from the sun," was the reply.

"That's just as good," responded the captain. "Where did you see it?"

"I was at the indicator when an officer went up and the hatch was raised. As he didn't push it all the way down I had an idea he might soon return, so I moved up and stood between the twin tanks to the right of the steps. When the officer raised the hatch a streak of sunlight went right across the under side at the corner of the door, and I knew it couldn't come in at the front port hole," said Ralph, with a glow of pleasure in the discovery.

The captain shook his head slowly, as he said: "I am afraid this will mean an additional source of worry to all of us; it is bad enough to be locked up and subjected to the guns of vessels and wars.h.i.+ps, but it will be doubly hazardous to pa.s.s through the mine fields, and avoid the nets."

"Do you know anything about them, and how and where they are located?"

asked Alfred.

"Yes, I have a pretty good knowledge of their location, and how to avoid them, although they constantly change the nets, or provide new safety outlets," said the captain.

[Ill.u.s.tration: _The Steel Nets_]

"What do you mean by safety outlets?" asked Alfred.

"Immense steel nets are stretched across the straits from Calais to Dover, two lines, in fact, between which the vessels plying between England and France go to and fro in safety. Furthermore, war vessels guard these nets on both sides, so that it would be a difficult matter to get near the nets," said the captain.

"But submarines do seem to get through somewhere; do they not?" asked Ralph.

"Yes; owing to their ability to make the trip under water, and taking advantage of the darkness, it is sometimes the case that they get through without being entangled in the nets," he replied.

"But how do the s.h.i.+ps that sail along the Channel get through?" asked Alfred.

"That is just what I was referring to when I spoke of safety outlets. At a certain point there is an opening through the nets at one side, through which vessels can pa.s.s into the line between the two wire cordons. The opening in the other line of nets is not directly opposite, but a mile or so off to one side, so that in order to get to the opening in the other nets, it is necessary for the s.h.i.+p to sail along in the safety zone between the two nets, and make a turn at right angles to get out through the second opening. That method has been found to be most effective, and is called the safety lane," responded the captain.

They were now in or near the most widely traveled part of the ocean on the western front of the continent. Thousands of s.h.i.+ps pa.s.s and repa.s.s that zone which reaches from the southern part of Ireland to the western coast of France, and it was remarkable that the submarine was able to move along up to this time on the surface without being detected.

Before the sun had gone down that night, however, they were compelled to submerge twice, and then the mantle of night shrouded the vessel and it moved along with more boldness. On this the fourth night of captivity, they were not locked in their prison.

"I cannot account for it," said the captain. "Possibly the commander has some little human sympathy left, and does not want to drown us like rats in a cage."

Neither the captain nor the boys slept much that night. They were too much occupied with constantly watching the manoeuvers necessary on the part of the commander and his crew to prevent detection as they pa.s.sed up the Channel.

"I have spent years on the Channel as a navigating officer and in charge of various types of s.h.i.+ps in the merchant service, as well as on our own naval vessels, and I know, probably, better than the lieutenant in charge of the submarine, what the dangers are. It is my belief that the lieutenant has come over this course before, and probably knows a safe, or measurably safe route, and has taken the chances of returning, but no one, however skilful a navigator he may be, can be sure of making exactly the same course twice. The tides may be against him; he may be out of his reckonings hundreds of feet, and that is too big a margin, where a hundred feet in width is the limit through which his vessel may pa.s.s in safety."

The captain thus, in general terms, set forth the perils of the route that the commander of the submarine had taken, and stated also, very plainly, that they must now be prepared to meet the greatest of all dangers. Sleep, therefore, could not be considered.

The long and weary night at last came to an end, and the appetizing odors of the morning meal were wafted to them. Their toilets were exceedingly simple affairs, a small cake of soap, warm water, and a long towel serving for the three. They had no trouble in dressing, for their clothing had not been removed. They were obliged to dispense with the bath, for, although all these boats are provided with comforts of that kind, none of them was available to the captain and the boys, and they did not ask that any privileges be extended to them.

No sooner had breakfast been served than the machinery began to slow down until finally it ceased. Not a perceptible motion was now observed.

A pulsator or two were at work, and a slight rumble due to the action of the dynamo came to their ears.

"I suppose we are now on the bottom," suggested Ralph.

"Yes; during the daytime it will be necessary to keep quiet. Even the periscope may reveal our presence," remarked the captain.

A little information as to the activities of the crew during these periods of rest may be interesting. Idleness breeds discontent and mischief. It is upon the principle that constant work encourages contentment and makes for efficiency, that the Germans require the continued activity which was shown by the occupants of the submarine.

The vessel was manned by twenty-seven officers and men. The personnel being as follows: A lieutenant, a sub-lieutenant, two under or petty officers, a physician, a cook and two oilers, two first-cla.s.s machinists, and seventeen helpers, or seamen, although it was evident, as the captain expressed it, that few of the helpers had seen much sea duty.

While it is customary to divide the duties on s.h.i.+pboard into three watches, during the period of twenty-four hours, so as to give each squad a period of service every day at a different period, it would be difficult to carry out the same regulations on board a s.h.i.+p of this character.

The captain said: "I notice that they have practically two watches, one taking up the duty from midday until twelve at night, and the other from midnight to noon. Yesterday, I noticed the same s.h.i.+ft that was on duty in the morning continued at work all the afternoon, so it is possible that every three or four days s.h.i.+ft No. 1, which works from noon to midnight, will be changed so that for the next four days the time for their services will be from midnight to noon."

Attention is called to this method of doing duty so that the reader may understand certain events which will be referred to later.
