to a hidden nation. But the fact that the language seemed to have no sister tongue on earth discouraged that. Between my tenth and fifteenth years Sam and I restlessly scoured the globe in search of a clue, but a decade before we had given it up. I turned to dreams of interplanetary travel with a passionate desire to explore space and venture to other worlds in search of my dream girl; but the space flier seemed as far in the future as it had done a hundred years before. To please me, however, Sam helped design and construct a model of a machine we called the Omnimobile--because it should be able to travel in all elements.

Could I believe that such a supernal being was merely a dream?CHAPTER III The Scarlet Pall The coming of the terror was slow and gradual enough--and as silent as the tomb! With all the magic of the quiet woodland beauty throbbing in my being, I was strolling up the narrow gravel walk toward the peaceful vine-covered cottage, where Sam was sitting in
