They stepped out of the transporters and rubbed their eyes in astonishment. Two of the huge slugs had been amazing, but the effect of half a hundred grouped about them was more than the mind could, for a moment, grasp. They were in a huge room composed apparently of the same silvery material of which the transporters were made. It rose above them in a huge dome with no signs of windows or openings. It was lighted by a soft glow which seemed to emanate from the material of the dome itself, for it cast no shadows. On a raised platform before them rested one of the huge slugs, a broad band of silvery metal set with flashing coruscating jewels clasped about its body. From the ornament and the exalted position, they judged that they were before the Grand Mognac of Mars. With a muttered word to Turgan to follow him, Damis advanced to the foot of the platform and bowed deeply. "I thank you for that mark of respect, Nepthalim," came a thought wave from the Grand Mognac, "but such forms are obsolete on Mars. Here all living intelligences are equal. Only the accident of superior mental power is allowed to differentiate between us and this added power brings only added and more arduous duties. You came here to get weapons which will free you from the dominance of the Jovians who rule you, did you not?" "We did, oh Grand Mognac," replied Damis. "Your prayers shall be answered if you are found worthy. Relate to me now all that has passed since the Jovians first landed on your planet. If you can form thoughts without speaking, you may save the effort of speech. The air has become so thin on Mars that sound will not carry over large portions of it. As a result, we have no organs of hearing, for they have been atrophied from ages of disuse. We use thought as our only means of communication." * * * * * Rapidly, Damis marshaled his thoughts in order. Slowly and carefully he pictured in his mind the landing of the Jovians as he had heard it described and then the event leading up to their trip. The Grand Mognac frequently interrupted him and caused him to amplify in detail some of the mental pictures and at times turned to Turgan and requested him to picture the same events. When Damis had finished the Grand Mognac was motionless for ten minutes.
