"When you have wicked thoughts don't look them in the eyes," said Edmund, half smiling, "and then you will run no danger. It is through the eyes that they read. Now, to resume what I was saying, I am more than ever anxious to recover the car, and to find the materials that will enable me to repair its machinery. With it in our possession, and in good shape, we shall be in a position to run away whenever it may seem necessary to do so, and in the meantime to impose our legend upon them by the possession of so apparently miraculous a means of conveying ourselves through space. It will be overwhelming proof of the truth of our assertion of an origin outside their world, and perhaps, upon the whole, it is just as well that they should think that we belong to the sun, of whose existence they have some knowledge, rather than to the earth, of which they know nothing, in spite of the inkling that Juba succeeded in conveying to them."

"The car is here, isn't it?" I asked.

"Yes, it is in the great tower, but it is useless in its present condition."

"And what materials do you want to find?"

"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.
