"We saw them investigate the planet. We saw them plan to destroy any people they found with a ray which was as follows: 'the ray which makes all parts move as one.' We could not understand and could not interpret. Thoughts beyond our knowledge have, of course, no meaning, even when our mental amplifiers get them, and bring them to us." "The Molecular ray!" gasped Morey in surprise. "They will be an enemy." "You know it! It is familiar to you! You have it? You can fight it?" asked Zezdon Afthen excitedly. "We know it, and can fight it, if that is all they have." "They have more--much more I fear," replied Zezdon Afthen. "At any rate, we saw what they intended. If our world was inhabited, they would destroy every one on it, and then other men of their race were to float in on their great ships, and settle on that largest of our worlds. "We had to stop them so we did what we could. We had powerful machines, which would amplify and broadcast our thoughts. So we broadcast our thought-waves, and implanted in the mind of their leader that it would be wise to land, and learn the extent of the civilization, and the weapons to be met. Also, as the ship drew nearer, we made him decide on a certain spot we had prepared for him. "He never guessed that the thoughts were not his own. Only the ideas came to him, seeming to spring from his own mind. "He landed--and we used our one weapon. It was a thing left to one group of rulers when the Ancient Masters left us to care for ourselves. What it was, we never knew; we had never used it in the fifteen thousand years since the Great Masters had passed--never had to. But now it was brought out, and concealed behind great piles of rock in a deep canyon where the ship of the enemy would land. When it landed, we turned the beam of the machine on it, and the apparatus rotated it swiftly, and a cone of the beam's ray was formed as the beam was swung through a small circle in the vertical plane. The machine leaped backward, and though it was so massive that a tremendous amount of labor had been required to bring it there, the push of the pencil of force we sent out hurled it back against a rocky cliff behind it as though it were some child's toy. It continued to operate for perhaps a second, perhaps two. In that time two great holes had been cut in the enemy ship, holes fifteen feet across, that ran completely through the hull as though a die had cut through the metal of the ship, cutting out a disc of metal.
