"Might be. I don't know. The metal thing may be a receiver for the occult force set up in the ether by the Lord of Flame—hypnotism by radio, perhaps, or something of the kind."
"Anyhow, as you said, it's damned queer, like everything else we've found here—excepting Xenora."
"Suppose we take the thing along, and open it up when we have time?"
He produced a pair of pliers, and we twisted the odd blue bar out of its frame, and carried it to the machine. It was oddly light to be metal, though it must have been an irksome burden to the one on which it was fastened. We got aboard again, and moved for the cover of the purple wood, for we did not know how soon relief would come for the fallen ship. But Xenora assured us that the Lunaks, as she called the flying things, quite frequently destroyed the ships of Mutron, and that the fate of this one would be laid to them.
CHAPTER XXIV
The Blue Prism
For perhaps thirty miles we drove the great machine through the brilliant forest, southward down a broad valley. At last we stopped in a little grove of tall flowering trees, close by the cool crystal stream. Beyond the grove was a little patch of green clearing with the great purple trees closing in all about it. It was a peaceful spot, weirdly beautiful, and it seemed secure enough. The unceasing wind was not so hot beneath the great trees, and they shielded us from the burning, crimson glare of the sky.
The Omnimobile seemed safely hidden beneath the masses of purple bloom; and whenever we were tired, or thought ourselves in danger, we could retire to the quiet security of its cool interior, behind the thick metal walls. Frankly, I hoped that our stay there would be a long one. I tried to forget the menace that hung over the earth.
Our life there was simple, and, for my part, I was supremely happy. Or not quite supremely, for I could not quite still my conscience. I was pretty well resigned to fate, however. With such a girl as Xenora, a man might be supremely happy anywhere. We tramped together about the grove, gathered the tiny, bright-red flowers in the green meadows, and bathed in the cool dark pools, where the river flowed beneath the purple trees. Sometimes she sang to me the folk-songs of her people, monuments of the high estate that Lothar had once enjoyed.
