"Edmund," he said earnestly, "I am beginning to be of Henry's opinion; you had better get away from here without losing a moment."

"No," said Edmund, "we'll not go yet. The time hasn't come to run away. What difference does it make even if Ingra does suspect that the car is moved by some mechanism instead of by pure magic? He could not understand it if I should explain it to him."

"But you have said that he is extraordinarily intelligent."

"So he is, but his intelligence is limited by the world he lives in, and while there are many marvelous things here, nobody has the slightest conception of inter-atomic force. They have never heard even of radioactivity. At the same time I don't mean that they shall go nosing about the car. I'll take care of that."

"But," said Jack, "it grinds me to see that brute Ingra get off scot-free after trying to murder us. And what has he got against us, anyway? But for him we should never have had any trouble. He was against us from the beginning."

"I don't think he was particularly against us at the start," said Edmund. "Only he was for treating us with less consideration than Ala was disposed to show. But after the first accidental shooting, and the drubbing that Juba gave him, naturally his prejudices were aroused, and he could hardly be blamed for thinking us dangerous. Then, when he found himself defeated, and his wishes disregarded, on all sides, he began to hate us. It is easy enough to account for his feelings. Now, since our recent astonishing triumph, being himself incredulous about our celestial origin, he will try to undermine us by showing that our seeming miracle is no miracle at all."

"And you gave him the chance by taking him in the car!" I could not help exclaiming.

"Yes," said Edmund, with a smile. "I admit that I made a mistake. I counted too much upon the influence of the sense of mystery. But it will come out all right."

"I doubt it," I persisted. "He will never rest now until he has found out the secret."

Nothing more was said on the subject, but Edmund was careful not to leave the car unguarded. It was always kept afloat, though in contact with the landing. The expenditure of energy needed to keep it thus anchored without support was, Edmund assured us, insignificant in comparison with the quantity stored in his mysterious batteries.
