"What d'you do to kill time? Well, I been thinking about knocking off the stuff for a while. Mame gets sore at me for having my fingers all stained up with nicotine like this."
He extended his hand, the first and second fingers of which were painted a bright yellow.
"Soap won't take it off," he remarked.
"A popular but inexcusable error," said the doctor. "It is the tarry by-products of tobacco which cause that stain. Nicotine itself, of course, is a volatile alkaloid base of which there is only the merest trace in tobacco. It is one of the deadliest of nerve poisons and is quite colourless. There is enough of that stain upon your fingers—if it were nicotine—to kill a dozen men."
"The hell you say!"
"Nevertheless, it is an indubitable fact. A lump of nicotine the size of the head of a pin placed on the tongue of a horse will kill the beast instantly."
The cowpuncher pushed back his hat and scratched his head.
"This is worth knowin'," he said, "but I'm some glad that Mame ain't heard it."
"Concerning the Cumberlands," said the doctor, "I—"
"Concerning the Cumberlands," repeated the cattleman, "it's best to leave 'em to their own concerns." And he started to turn away, but the thirst for knowledge was dry in the throat of the doctor.
"Do I understand," he insisted, "that there is some mystery connected with them?"
"From me," replied the other, "you understand nothin'." And he lumbered down the steps and away.
Be it understood that there was nothing of the gossip in Randall Byrne, but now he was pardonably excited and perceiving the tall form of Hank Dwight in the doorway he approached his host.
"Mr. Dwight," he said, "I am about to go to the Cumberland ranch. I gather that there is something of an unusual nature concerning them."
"There is," admitted Hank Dwight.
"Can you tell me what it is?"
"I can."
"Good!" said the doctor, and he almost smiled. "It is always well to know the background of a case which has to do with mental states. Now, just what do you know?"
"I know—" began the proprietor, and then paused and eyed his guest dubiously. "I know," he continued, "a story."
"Yes?"
"Yes, about a man and a hoss and a dog."
"The approach seems not quite obvious, but I shall be glad to hear it."
There was a pause.
"Words," said the host, at length, "is worse'n bullets. You never know what they'll hit."
"But the story?" persisted Randall Byrne.
"That story," said Hank Dwight, "I may tell to my son before I die."
"This sounds quite promising."
"But I'll tell nobody else."
"Really!"
"It's about a man and a hoss and a dog. The man ain't possible, the hoss ain't possible, the dog is a wolf."
He paused again and glowered on the doctor. He seemed to be drawn two ways, by his eagerness to tell a yarn and his dread of consequences.
"I know," he muttered, "because I've seen 'em all. I've seen"—he looked far, as though striking a silent bargain with himself concerning the sum of the story which might safely be told—"I've seen a hoss that understood a man's talk like you and me does—or better. I've heard a man whistle like a singing bird. Yep, that ain't no lie. You jest imagine a bald eagle that could lick anything between the earth and the sky and was able to sing—that's what that whistlin' was like. It made you glad to hear it, and it made you look to see if your gun was in good workin' shape. It wasn't very loud, but it travelled pretty far, like it was comin' from up above you."
"That's the way this strange man of the story whistles?" asked Byrne, leaning closer.
"Man of the story?" echoed the proprietor, with some warmth. "Friend, if he ain't real, then I'm a ghost. And they's them in Elkhead that's got the scars of his comin' and goin'."
"Ah, an outlaw? A gunfighter?" queried the doctor.
"Listen to me, son," observed the host, and to make his point he tapped the hollow chest of Byrne with a rigid forefinger, "around these parts you know jest as much as you see, and lots of times you don't even know that much. What you see is sometimes your business, but mostly it ain't." He concluded impressively: "Words is worse'n bullets!"
"Well," mused Byrne, "I can ask the girl these questions. It will be medically necessary."
"Ask the girl? Ask her?" echoed the host with a sort of horror. But he ended with a forced restraint: "That's your business."
CHAPTER III
THE DOCTOR RIDES
Hank Dwight disappeared from the doorway and the doctor was called from his pondering by the voice of the girl. There was something about that voice which worried Byrne, for it was low and controlled and musical and it did not fit with the nasal harshness of the cattlemen. When she began to speak it was like the beginning of a song. He turned now and found her sitting a tall bay horse, and she led a red-roan mare beside her. When he went out she tossed her reins over the head of her horse and strapped his valise behind her saddle.
"You won't have any trouble with that mare," she assured him, when the time came for mounting. Yet when he approached gingerly he was received with flattened ears and a snort of anger. "Wait," she cried, "the left side, not the right!"
He felt the laughter in her voice, but when he looked he could see no trace of it in her face. He approached from the left side, setting his teeth.
"You observe," he said, "that I take your word at its full value," and placing his foot in the stirrup, he dragged himself gingerly up to the saddle. The mare stood like a rock. Adjusting himself, he wiped a sudden perspiration from his forehead.
"I quite believe," he remarked, "that the animal is of unusual intelligence. All may yet be well!"
"I'm sure of it." said the girl gravely. "Now we're off."
And the horses broke into a dog trot. Now the gait of the red roan mare was a dream of softness, and her flexible ankles gave a play of whole inches to break the jar of every step, the sure sign of the good saddle-horse; but the horse has never been saddled whose trot is really a smooth pace. The hat of Doctor Byrne began to incline towards his right eye and his spectacles towards his left ear. He felt a peculiar lightness in the stomach and heaviness in the heart.
"The t-t-t-trot," he ventured to his companion, "is a d-d-d-dam—"
"Dr. Byrne!" she cried.
"Whoa!" called Doctor Byrne, and drew mightily in upon the reins. The red mare stopped as a ball stops when it meets a stout wall; the doctor sprawled along her neck, clinging with arms and legs. He managed to clamber back into the saddle.
"There are vicious elements in the nature of this brute," he observed to the girl.
"I'm
