a pocket compass. His startled exclamation brought other members of the crew around him. The magnetic needle was apparently describing a semicircle. U75 was swinging round her anchor.

Just then a bell tinkled, and a disc oscillated on the indicator board on the bulkhead. Instantly the two men who had been told off as attendants upon the diver hurried aft, while their companions crowded expectantly around the door.

The two men came back, staggering under the weight of the diver. They had already removed his head-dress and leaden weights. Water dropped from his rubber suit. His face was livid, his eyes wide open and rolling. One of his bare hands was streaked with blood that flowed sullenly from a cut in his numbed flesh.

Kapitan Schwalbe and Leutnant Rix followed him into the crew-space. It was not through feelings of compassion that they had come for'ard. It was acute anxiety to hear the diver's report.

The luckless man was laid upon the mess-table. His attendants divested him of his diving-suit, and rubbed his body with rough towels. A petty officer poured half a glass of brandy down his throat.

"What is amiss?" Kapitan Schwalbe kept on repeating.

With a great effort the diver sat up.

"An anchor, sir," he gasped feebly. "An anchor—an English naval pattern one—has been dropped right over ours. A very big one."

Then his eyes closed, and he fell back unconscious.

"Gott in Himmel!" ejaculated Rix. "We are trapped!"

CHAPTER VIII Balked by a Sea-plane

"How so?" demanded Kapitan Schwalbe. "If we keep quiet, the cruiser—for cruiser she must be, judging by the fellow's description—will weigh and proceed."

"When she does weigh we are undone," said Rix despondently. "We are swinging round our anchor. For all we know, our cable has taken a turn round hers. As soon as they heave up their anchor, our anchor and cable will be brought up with it, and then the game is up. Either the strain will overcome our dead weight and we will be hauled to the surface, or else they'll lower one of their brutal explosive charges."

"The situation is serious," admitted Schwalbe in a low tone, for his Leutnant's words had produced a demoralizing effect upon the men. "How much cable have we inboard?"

Rix repeated the question. A petty officer doubled forward to consult the cable indicator. U75's anchor, when under way, was housed in a trough on the under side of the submarine's forefoot. The cable was automatically ranged in a compartment between the inner and outer skins, the space being always filled with water. The inboard end of the cable was not shackled; but to prevent its being able to take charge and run out, an indicator was placed on the bulkhead nearest to the cable tier. The amount of chain let go was regulated by a compressor, which was actuated from within the hull by means of levers and cranks, watertight glands being provided to prevent any leakage into the interior of the submarine.

"Seventy-five fathoms," reported the petty officer. "When we commenced to swing we paid out the length we had taken on board when we hove short."

"We must sacrifice the lot, Herr Rix," decided Kapitan Schwalbe. "There is no time to lose. Storm or no storm, we must slip and run for it."

It was U75's only chance, but it left her with only a small stockless kedge-anchor and chain, insufficient to withstand a heavy strain.

The compressor was released. With a loud rumble, for every sound was magnified within the confined space, the rest of the cable was allowed to take charge. It did so promptly, the end of the chain giving the hull a defiant smack as it did so. U75, no longer held by her anchor, began to drift with the tide, scraping dismally over the bed of Helwich Channel.

Schwalbe was now back at his post in the conning-tower. He dare not take the submarine to the surface until he had put a safe distance between him and the anchored British warship. Nor did he care to order the ballast tanks to be blown. Rather than allow the "pumping" of the seas to hammer the submerged craft upon the hard sand, he preferred to take the risk of letting her drag.

Fortunately the tide set evenly along the bed of the channel. A cross-current would have set the submarine upon the jagged rocks of the hidden West Helwick Ridge. Nevertheless there was always the danger of being hurled violently against a detached rock, or of fouling a live mine if by chance the British had laid obstructions in the channel.

Both Ross and Vernon knew the danger, but, manfully concealing their misgivings, they watched the faces of those of the crew who were "watch below". Most of the men were Frisians, broad-shouldered, blonde-featured, and generally devoid of fear. Yet the ceaseless strain upon the nerves had already begun to tell. As hardy fishermen, they would not have hesitated to launch their open boats in a storm to go to the rescue of a hapless vessel aground on the grim sand-banks of the Frisian shore. As the conscript crew of the submarine, compelled to keep within the limits of a steel box that almost momentarily threatened to be their tomb, their natural bravery was quenched.

Many of them sat upon their lockers, stolid-faced men who had already tasted of the bitterness of death. Others showed unmistakable signs of excitement, bordering on frenzy. They dreaded their life of modern piracy. The idea of sinking hapless merchantmen was repugnant to them, for they understood the brotherhood of the sea. It would be different if they were called upon to attack an armed British ship of war. They had no option but to obey their junker officers, who in turn were compelled to accept the misguided orders of the arch-pirate, von Tirpitz.

They were disheartened, too, for reports, in spite of the vigilance of the officers to conceal them, had reached them of the losses inflicted upon other unterseebooten. Occasionally they heard of a submarine crew being saved, but generally it was a case of total loss of all on board, by some hitherto unknown means, at the hands of the British Navy.

A hand touched Ross lightly on the shoulder. Turning, he saw Hans Koppe standing in a darkened corner of the compartment.

"Can you tell me this, mein herr?" asked the seaman in a low tone. "Is it true that the English give no quarter to German seamen in submarines?"

"I shouldn't think that they would refuse to do so," replied Trefusis. "Of course, I can quite understand that an opportunity doesn't often occur; but I've heard of several instances in which your U-boats have surrendered, and the crews have been treated exactly the same as other prisoners of war."

"I have heard differently," said Hans, "but I hope it's a mistake. I have a feeling that we won't see Wilhelmshaven again. And I have a wife and six children at Flensburg. Our Kapitan, too, expects that we might be denied quarter, because we have sunk your merchantmen. Believe me, I regret having done so, but we have orders. Do you know why Kapitan Schwalbe took you on board?"

"Because a certain German agent wanted us out of the way, I suppose," replied Ross.

"Perhaps," admitted Hans Koppe. "But in the event of our being captured he thinks that his good treatment of you will be in his favour. We are, I do not mind telling you, in a very tight corner. Our fuel supply is almost run out. We cannot hope to return home by way of the Straits of Dover. Not one of our submarines has tried that passage of late without meeting with disaster—at least, so I heard der Kapitan tell der Leutnant. Ach! It is deplorable, this war."

The rapid ringing of a gong was the signal for the watch below to turn out. A peculiar hissing noise proclaimed the fact that the ballast tanks were being emptied. U75 no longer grated over the bottom; her motors were running almost dead slow.

Although submerged, the submarine was "pumping" violently. Seasoned men were prostrate with sea-sickness. The air, in spite of chemical purifiers, was becoming almost intolerable. Everything movable was being thrown about in utter disorder, while to add to the discomfort of the crew the covering-plates of one of the lubricating-oil tanks had been strained, and at every jerk jets of viscous fluid would squirt through the fracture and trickle sullenly over the floor of the crew-space.

Since the watertight doors were still closed, Ross and Vernon were unable to get back to their bunks. Feeling thoroughly wretched, they were glad to accept Hans Koppe's offer to lie down on a long locker.

At noon, U75 came to the surface. The storm, being short forecasted, had quickly blown itself out, but the waves still ran high.

It was a prearranged plan on the part of the three U-boats operating in the English and Bristol Channels to communicate with each other by wireless at noon and at midnight. U75's wireless had a range of about 180 miles, and although it could be "jammed", the call could not be tapped by vessels other than the one for which it was intended. To make doubly sure, the messages were sent in code.

For nearly ten minutes U75 "made her number" without eliciting any reply. Perhaps it was well that Kapitan Schwalbe did not know what had happened to her consorts. U74 was at that moment lying on her side at the bottom of a Welsh harbour, her crew poisoned by the chlorine fumes from her batteries—the result of a rash curiosity on the part of her Lieutenant-Commander to investigate the approaches to the anchorage. As for U77, she was flying blindly for safety, with a couple of destroyers hard on her track, and a naval sea-plane overhead to direct them in their search.

Foiled in her efforts to get in touch with her consorts, U75 remained awash. The heave of the sea made it most difficult for her to use her periscope with certainty, for she had chosen a bad pitch on her ascent—the furious "overfalls" or "tide-rips" to the west of Lundy Island.

"We'll pay another visit to St. Mena's Island, Herr Rix," decided Kapitan Schwalbe, after the two officers had discussed the sinister matter of their futile attempt to make use of the wireless. "To-night at nine o'clock ought to suit. If we cannot get von Ruhle to see our signals—for my own part, I doubt whether he is in these parts—we'll have to do our best to get ashore. Meanwhile, keep a bright look-out. If we see any likely vessel coming this way, we'll try our luck once more."

"Message just received, mein herr," announced the wireless operator.

"From whom?" enquired Kapitan Schwalbe eagerly. He was devoutly hoping that either U74 or U77 had been able to "call up".

"I cannot say, sir," replied the man as he handed a code message to his superior.

Decoded, the "wireless" was as follows:

"Station 41 to unterseebooten. Two hundred gallons of fuel available here. Will be on the look-out for signals at 1 a.m."

The message was a "general call" for a secret petrol depot to any German submarine operating in the vicinity. Reference to the list of stations showed that "41" was at Port Treherne, a remote cove on the North Cornish coast about fifty miles from St. Mena's Island.

"I suppose it's safe," remarked Rix.

"With due precautions—yes," rejoined Kapitan Schwalbe. "At any rate, petrol we must have. Where's the chart? Ah, there we are! It looks a fairly easy place to approach, don't you think? The only danger from a navigation point is apparently this ledge of rocks—Lost Chance Reef, it's called. What unpleasant names these Englishmen give to their coasts!"

At that moment the Unter-leutnant, who happened to be at the conning-tower periscope, reported that a large vessel was bearing down towards them.

Kapitan Schwalbe hurried to the conning-tower. The object depicted was that of a modern tank-vessel about four hundred feet in length. She was low in the water, showing that she was
