“He didn't do it. He couldn't do it. My Bob couldn't do such a thing. It's some terrible mistake. Oh, my husband! My dear, thoughtless, impulsive husband! Oh, Bob! Bob! Come back and face them and tell them you didn't do it. Only tell me, and I'll believe you and stick by you through everything.”

And then the horrible thought that he was guilty; that even now he was being hunted, hatless, hungry, weary and thirsty—a pariah with every honest man's hand raised against him—reminded her that the limit of her wretchedness lay, not in the fact that her faith in him had been shattered, but in the more appalling consciousness that he would not come back to her! Wild herald of woe and death, he had flitted into her life—as carelessly as he came he had departed, and she knew he would not come back.

Yes, Bob was too shrewd a man not to realize that in abandoning his hat he had left behind him the evidence that must send him to the penitentiary should he ever return to his old haunts in Inyo and Mono counties. He loved his liberty too well to sacrifice it, and he knew her code. It did not seem possible to Donna that he would have the audacity to face her again; so, man-like, he would not try.

And then she would think of him as she had seen him that first night, leaning on Friar Tuck's neck and gazing at her in the dim ghostly light of a green switch-lantern—telling her with his eyes that he loved her. She recalled his little mocking inscrutable smile, the manhood that had won her to him when first they met, and against all this she remembered that she had presented him with the hat which the express messenger had showed her—she had seen him write his name in indelible pencil under the leathern sweat-band!

She knew he had ridden north from San Pasqual the night before the hold-up—and thirty-five miles was as much as one small tough horse could do in the desert between the hour at which Bob had left her and his presumable arrival at Garlock, where he lay in wait for the stage. The automatic gun, the hat, the khaki clothing, the blue bandanna handkerchief which the bandit had used for a mask, the fact that he was mounted—all had pointed to her husband as the bandit. But the description of the horse was at variance with the facts, and moreover—Donna thought of this on the third day—where had Bob gotten that rifle with which he killed the express messenger's horse?

He had no rifle when he entered San Pasqual that first night, and he had had none when he left. The hardware store always closed at eight o'clock, and it had been ten o'clock when Bob left the Hat Ranch—so he could not have purchased a rifle in San Pasqual. He could not have gotten it in the desert between San Pasqual and Garlock, for in the desert men do not sell their guns, and if Bob had taken the gun by force from some lone prospector, news of his act would have drifted into San Pasqual next day.

It was then that Donna ceased sobbing and commenced to think, for even if her head inclined her to weigh the evidence and render a verdict, her heart was too loyal to accept it. The memory of Bob McGraw was always with her—his humorous brown eyes, the swing to his big body as he walked beside her, big gentleness, his unfailing courtesy, his almost bombastic belief in himself—no, it was not possible that he could be a hypocrite. That perverse streak in him, the heritage of his Irish forebears, would not have permitted him to run from the messenger. The man with courage enough to turn outlaw and rob a stage had courage enough to kill his man, and Bob McGraw would have fought it out in the open, He would never have taken to the shelter of a sand-dune and fired from ambush. Bob McGraw, having brains, would have killed the messenger and gone back for his hat! He was too cunning a frontiersman to leave a trail like that behind him and it was no part of his nature to do a half-way job. Still, the man who had robbed that stage had had no hobbles on his courage. Why, if he—he must have had a reason for not caring to recover that hat—When the desert-bred think, they think quickly; their conclusions are logical. They always search for the reason. The man whose desperate courage had been equal to that robbery—who had accomplished his task with the calm ease and urbanity which proclaimed him a finished product of his profession, should have argued the question with the messenger at greater length! He should have disputed with him possession of the hat, for in the desert a hat is more than a hat. It is a matter of life and death, and when the outlaw had abandoned his hat it must have been because he knew where he could secure another before day should dawn and find him bareheaded in the open. Had Bob been the robber he would have remembered that his name was in the hat, and rescued it, even at the price of the express messenger's life, for self-preservation is ever the first law of nature. On the other hand, if the bandit had known that the name was in the hat—

The mistress of the Hat Ranch rose from her bed, while a wild hope beat in her breast and beamed in her tear-dimmed eyes. She went into the room where she kept her stock of hats and began a careful examination of each hat. Nearly all bore some insignia of ownership. Derby hats invariably carried the owner's initials in fancy gilt letters pasted inside the crown, while others had the initials neatly punched in the sweat-band by a perforating machine. Half a dozen hats, apparently unbranded, had initials or names in full written in indelible pencil inside their sweat-bands.

Donna, considered an authority on male headgear, was for the first time learning something of the habits of men—the too frequent necessity for quickly identifying one's hat from a row of similar hats from the hat-hooks in crowded restaurants. Outwardly the hats of all mankind resemble each other, and for the first time Donna realized that it was the habit of men to mark them. She pondered.

“Now, here is a hat bearing the name of James Purdy. Suppose I should sell this hat to Dan Pennycook (unconsciously she mentioned Mr. Pennycook, who dared not buy a hat from her) and he should hold up the stage and have the hat shot off his head. The express messenger who picked it up would go looking for a man named James Purdy. Perhaps—”
