"We will take your weapons, Martian, and with them go to Earth. If it be His will that Lura be safe, safe shall she be although the whole force of Jupiter threaten her. If not, His will be done. One promise I exact of you, Turgan. When we have reached Earth and I have taught your followers to use the Martian weapons, you will give me a crew and let me depart to Venus to find her." "Gladly will I promise, and if I be spared, I will go with you, Damis," said Turgan. "Do not think that Lura is not dear to me; she is dearer than all else in the Universe save only the keeping bright the ideal of loyalty that has been the guiding light of the Terrestrials for untold ages." "Your decision is well made, Nepthalim," said the Martian, "and word of it shall be given to the Grand Mognac that he may know that he made no mistake when he entrusted you with the weapons of Mars. Now for your course. When you rise, direct your ship toward Deiphos. The Jovian fleet is now at an ascension of forty-two degrees and at an angle of one hundred and sixty degrees from the sun. Deiphos will hide you from their instruments. Once you reach it, our observers will plot your course and send you a bearing which will take you as far from the Jovian fleet as possible. They are now passing Ceres and will soon be out of the asteroid belt. They are larger and more powerful than the ship you are flying and they will make better speed. However, if you use your maximum power, you will easily arrive on your planet before them. Have you fuel enough for your trip at full speed?" Damis hastily inspected the fuel supply of the ship and made some rapid calculations. "We have enough to carry us at maximum speed to Earth and to retard us to a safe landing, but very little to spare. Can you give us some?" "There is no tantalum on Mars except a little scattered through tons of rock. It would take us days to extract enough to do you any good. It is well that you did not plan to fly to Venus for you could have made little speed and the Jovian flyer would have reached there long before you did. Now go, and may our best wishes aid you in your flight." * * * * * Damis turned and instinctively held out his hand. A trace of expression flickered over the face of the nearest Martian slug and he bent forward and clasped the proffered hand in one of the many hands with which he was provided. No further message came to Damis from the Martians and he entered the airlock with Turgan following him. As the lock clanged shut, he turned to his companion. "Open the reserve air tanks and restore the atmosphere gradually to the pressure of Earth," he directed. "Unless you do that, we will be unable to function efficiently."
