He firmly believed in the power of the latter's fulgurator, and had no doubt whatever that the inventor had conceived an engine that was capable of revolutionizing the condition of both offensive and defensive warfare on land and sea. He was aware that the demon of insanity had respected the man of science, and that in Roch's partially diseased brain the flame of genius still burned brightly.

Has she been delayed by a buccaneering cruise in the neighborhood of Back Cup? It seems to me that Ker Karraje's only desire would be to get back with the sections of Roch's engines as soon as possible. Maybe the Virginian foundry had not quite finished them. Engineer Serko does not display the least anxiety or impatience.

I now know that at any rate it is not easy to regulate the aim of Roch's auto-propulsive engine. It is probable that it always bursts at the same distance, and that beyond the zone in which the effects of the fulgurator are so terrible, and once it has been passed, a ship is safe from its effects. If I could only inform the world of this vital fact! August 20.

I saunter, without any fixed idea, towards Thomas Roch's laboratory. This reminds me of my compatriot. I am, on reflection, disposed to think that he knows nothing about the presence of a squadron off Back Cup. Probably not until the last moment will Engineer Serko apprise him of its proximity, not till he brusquely points out to him the vengeance he can accomplish.

Meanwhile, for aught I know I may hear the thunder of Roch's fulgurator as it destroys the ships approaching to make a night attack. I take a last look round. On the opposite side a light, a single light, is burning. It is the lamp in Roch's laboratory and it casts its reflection upon the waters of the lake.

Thomas Roch's invention having been refused by the commission, steps ought to have been taken to prevent him from offering it elsewhere. Nothing of the kind was done, and there a great mistake was made. The inevitable was bound to happen, and it did.

The Americans, being even more practical than the English, did not attempt to bargain for Roch's fulgurator, to which, in view of the French chemist's reputation, they attached exceptional importance. They rightly esteemed him a man of genius, and took the measures justified by his condition, prepared to indemnify him equitably later.

"When he has obtained possession of Roch's fulgurator whose power is, so to speak, without limit, Ker Karraje will be in a position to carry on his crimes with complete impunity. "It is therefore urgent that the states interested should destroy his lair without delay.

Yes, it would have been far better if I could have remained Thomas Roch's keeper here, as in Healthful House. For fifteen days I see nothing of my late charge. No one, I repeat, has placed any obstacles in the way of my daily peregrinations. I have no need to occupy myself about the material part of my existence.

These pirates are obviously certain that they will be able to annihilate their assailants as soon as the latter enter the dangerous zone. Their confidence in Roch's fulgurator is absolute. Absorbed by the idea that these warship are powerless against them, they think neither of the difficulties nor menaces held out by the future.
