As he finished his head slumped forward on his chest. With an exclamation of dismay Dr. Bird sprang forward and tried to lift the prostrate form.
In an agony of desire the Doctor tightened his grip on the dying man’s shoulder. But Smith collapsed into a heap. Dr. Bird bent forward and tore open his shirt and listened at his chest. Presently he straightened up.
“He is gone,” he said sadly, “and I guess the results of his genius have died with him. He doesn’t strike me as a man who left overmuch to chance. Carnes, is your case completed?”
“Very satisfactorily, Doctor. I have both of the lost packets.”
“All right, then, come back to the wreck and help me pack my burros. I can make my way back to Fallon without a guide.”
“Where are you going, Doctor?”
“That, Carnes, old dear, is none of your blankety blanked business. Permit me to remind you that I am on my vacation. I haven’t decided yet just where I am going, but I can tell you one thing. It’s going to be some place where you can’t call me on the telephone.”
