"In a way," said Morey seriously, "it was distinctly fortunate that we were attacked almost at once. Their instantaneous system of destruction would have worked for the one shot needed to send the Ancient Mariner to eternal blazes." He laughed, but it was a slightly nervous laugh.

The terrestrial ship landed in a great grassy court, and out of respect for the parklike smoothness of the turf, Arcot left the ship on its power units, suspended a bit above the surface. Then he, Morey and the Talsonian left the ship. Zezdon Afthen was left with the ship and with Wade in charge, for if some difficulties were encountered, Wade would be able to help them with the ship, and Zezdon Afthen with the tremendous power of his thought locating apparatus, was busy seeking out the Thessian stronghold.

A party of men of Talso met the terrestrians outside the ship.

"Welcome, Men of another world, and to you go our thanks for the destruction of one of our enemies." The clear thoughts of the spokesman evinced his ability to concentrate.

"And to your world must go our thanks for saving of our lives, and more important, our ship," replied Arcot. "For the ship represents a thing of enormous value to this entire star-system."

"I see—understand—your—thoughts that you wish to learn more of this weapon we use. You understand that it is a question among us as to whether it is undefeatable, uncontrollable or just un-understandable. We have had fair success with it. It is not a weapon, was not developed as such; it was an experiment in the line of electric-waves. How it works, what it is, what happens—we do not know.

"But men who can create so marvelous a ship as this of yours, capable of destroying a ship of the Thessians with their own weapons must certainly be able to understand any machine we may make—and you have power?" he finished eagerly.

"Practically infinite power. I will throw into any power line you suggest, all the direct current you wish." Arcot's thoughts were pure reflection, but the Talsonian brightened at once.

"I feared it might be alternating—but we can handle direct current. All our transmission is done at high voltage direct current. What potential do you generate? Will we have to install changers?"

"We generate D.C. at any voltage up to fifty million, any power up to that needed to lift ten trillion men through their own height in this time a second." The power represented approximately twenty trillion horsepower.
