"You know him, then?"

"No, but I know of him. Why, that fellow was one of the greatest surgeons in the country until a year ago! He went all to pieces in a hurry and dropped out of sight; it was more or less hushed up, of course, but in professional circles the truth is known. It was caused by morphia; the poor fellow; must have been a hopeless victim."

"He does not look it now," said Tom Lee. His features contracted slightly. "Morphia! And that goes back to opium again. All the more need of our getting to work without further delay, Doctor Scudder! You will remain here for a time?"

Scudder's eyes went for an instant to the door of the other room.

"Yes, as long as you want me," he rejoined. "In fact, I think I'll remain here until things shape up right, then return to San Francisco for my things, and come back here for good. I'll want to keep an eye on the building work."

Silently, without a word, Tom Lee took from a table beside the bed a little round cup of horn. Once it had contained a brownish substance, but now it was scraped clean inside, scraped down to the very horn. Silently, he held it out to the doctor. It was an opium toy.

Scudder smiled and nodded as he took the little cup. "I'll attend to it at once," he said, and rose. "Do you like this desert country as much as you expected?"

"Yes," said Tom Lee gravely. "It is wonderful; it is ideal! I like it for itself, no less than for our purpose. I am an American; I love this country, I am part of it—and this desert is to me like the great wilderness of my own Shensi, the very heart of the ancient land, full of great unguessed things and strange powers! Yes, I like this desert."

Scudder, shrugging his shoulders as though to indicate that it was all a matter of choice, turned away. At the door of the other room, Claire halted him.

"Doctor! Is it true—what you said about Doctor Murray?"
