stood a tall and emaciated white man.
"Aimu!" said the Indians reverently, and bowed themselves.
Over the bare, brown backs, the white man looked at Hale.
"Sir Basil Addington?" asked the young man.
"Yes. You are welcome. Come in."
Hale entered the building.
HE was in a book-filled study, furnished with hand-made chairs and a desk. Sir Basil asked him to be seated. He offered the young man long, brown native cigarettes and a very good drink made from yucca.
After several minutes of conversation, Sir Basil suddenly changed his manner.
"And now," he shot out, eyeing the young man through narrowed lids, "will you please state the purpose of this visit?"
Hale looked squarely at his questioner. "Frankly, Sir Basil, I have called on you because I am so intensely interested in your work among the Ungapuks that I wish to offer my services."
He gave in detail his family history, his education, and his experience as a teacher and a scientist.
Sir Basil tapped his teeth thoughtfully with a pencil.
"But why do you think you can be of assistance to me?"
"That, of course, is for you to decide."
Hale thought that the scientist looked like a huge, starved crow in his loose-fitting coat. He was so fleshless that, when the light fell strongly on his face as it now did, the bones of his head and hands showed through the skin with horrible clearness.
Hale, under Sir Basil's scrutiny, decided instantly that he did not like him.
"I need a helper," the scientist went on, with the air of talking to himself. "A white assistant who neither loves nor fears me. Unani Assu is good enough in his way, but I need a helper who has had technical training." Suddenly he wheeled on Hale and asked sharply, "How are your nerves, young man?"
HALE started, but managed to answer calmly. "Excellent. My war record isn't half bad, and that was surely backed with good nerves."
"And you say you have no close relatives, no ties of any sort to interfere with work that is dangerous--and something else?"
"Not a soul would care if I passed out to-day, Sir Basil."
"Good! And now tell me this: are you one of those scientists whose minds are so mechanical, so mathematically made, as it were, that your entire outlook on science is based on old, established beliefs, or do you belong to that rare but modern type of trained thinker and dreamer who refuse to permit yesterday's convictions to influence to-day's visions?"
Hale smiled quietly. "I recently lost my chair in a famous university because of my so-called unscientific teachings regarding ether-drift."
Expressing himself in purely scientific terms, he went into an elaboration of his revolutionary theory. When he had finished, Sir Basil reached out his clawlike hand to him.
"Good!" he approved. "You have dared to think originally. Now listen to my theory of mind-electrons which has grown into the established fact that I have discovered the secret of life and death."
The long, thin hands reached into a pocket for a box of pills. He swallowed one greedily, and immediately his emaciated face seemed charged with new virility.
He spoke out suddenly. "Our world, you know, is made up of three powers: matter, energy and what you call life. I might really say that there are but two powers, for matter, in its last analysis, is a form of energy. And what is life? You can't call it a form of energy, for every inorganic atom has
