"Primarily nothing but uranium. They understand chemistry here. They have the apparatus that I need, but they do not know how to use it as I do. The uranium certainly exists somewhere. They mine gold and silver, and other things, and when I can find their mines, without exciting their suspicion, and can get the use of a laboratory in secret, I shall soon have what I need. But I must be very circumspect, for it would not do to let them perceive that chemistry really lies at the basis of our miracle. It is this necessity for secrecy which troubles me most. But I shall find a way." "For God's sake, find it quick," Henry burst out. "And then get away from this accursed planet." Edmund looked at him a moment before replying: "We shall go when the necessity for going arises, and not before. We have not yet seen all the interesting things of this world." I believe that even Jack and I shared to some extent Henry's disappointment on hearing this announcement. We should have been glad to know that we were to start on the return journey as soon as the car was in shape to transport us. But the event proved that Edmund's instinct was, as usual, right, and that the things which were yet to be seen and experienced were well worth the fearful risk we ran in remaining. While Edmund undertook the delicate inquiries which were necessary in order to determine the direction that his search for uranium should take, and to enable him to conduct his chemical processes without awaking suspicion as to his real purpose, we were left much of the time in charge of a party of attendants who, by his intercession, had been selected to act as our guides when we wished to examine the wonders of the palace and the capital. Sometimes he accompanied us; but more often he was with Ala and her suite, including her uneludable satellite, Ingra. "I bless my stars that he doesn't favor _us_ with his delightful company," was Jack's comment, when he saw Ingra tagging along after Ala and Edmund. I privately believed that Ingra had his spies among our attendants, but I was careful not to mention my suspicions to Jack.
