"By eliminating certain means of offence you reduce the limits of the horrors of war."
"Of the means only, the horrors of war will never be mitigated until the ban upon explosive shells, submarine, and aerial offence and defence is imposed. Thus I maintain that the Geneva Conference has only taken a middle course. Better by far to place no limitations and make war so horrible that no nation will dare draw the sword; or else restrict the weapons of offence to solid armour-piercing shells for naval warfare, small calibre rifle bullets and cold steel. To my mind submarine warfare, including torpedo work, is a despicable form of destruction."
"Yet you yourself are bent upon an errand of destruction by means of your submarine."
"Precisely. And it is the same in international warfare, because A builds a submarine, B must do likewise, in order to fight upon equal terms. But wait until to-morrow. When you have explored ’La Flamme’ perhaps you may see eye to eye with me."
"What caused the disaster, sir?" asked Hythe.
"For the present I prefer not to answer that question," was the reply. "To-morrow I think I can explain more clearly."
After breakfast on the following morning a strong working-party, under the direction of the chief officer, prepared to tackle the task of freeing the propeller. Clad in their diving suits the men entered the air-lock and thence slipped out into the sea. Soon the hull resounded to the rasping of the hack-saws as the men attacked the hempen rope that was coiled tightly round the shafting.
"Are you ready, Mr. Hythe?" asked the captain.
The sub assented, and Captain Restronguet led the way for’ard to the divers’ dressing-room. On the way he stopped, and asked his companion to accompany him to the after-conning-tower.
The sun was now shining brightly, and even at that depth the luminosity was sufficient to enable the interior of the conning-tower to be seen without the aid of artificial light.
"It is now nine o’clock," remarked Captain Restronguet. "On what quarter ought the sun to be visible at this hour?"
"Now look at its bearing according to our standard compass."
"Exactly. Now that explains the loss of ’La Flamme.’ Practically the whole of this coast contains vast quantities of iron ore, and the deviation of the compass at this particular spot amounts to as much as ninety degrees. The north-west coast of Spain is bad enough in this respect. You may have heard of the loss of the ’Serpent,’ several years ago. That was attributed to magnetic influence of the iron ore upon the ship’s compass. Here the error is still greater. It is easy to understand that the unfortunate submarine, getting within the fatal influence of the magnetic attraction, ran full tilt upon the rocks in a heavy sea and on a pitch-dark night. But we will now prepare for our submarine walk."
