The roaring of engines which Huldah had mentioned as on the Magdalena Branch came more distinctly now. “Looks like there must be three or four of ’em—engines—one right behind t’other,” the old woman muttered. “I’ll jest git you fixed comfortable over here, honey, and shut them winders, an’ then I must run back.”

But when she would have done so, the girl clung to her with shaking hands. “Oh, don’t leave me!” she sobbed. “Don’t let that man know where I am. Hide me.”

“He ain’t your husband, then?” hazarded Huldah.

“No—no—no!” moaned the girl. “My husband’s a freight conductor on this road—Billy Gaines. You’ve seen him. He told me about you and the Wagon Tire House—about your having a wagon tire in front of it to beat on to call to meals. I expect he’s eaten many a meal here. He might come now; and then if he saw me—and that man—and—oh, hide me!”

Aunt Huldah let the head rest upon her shoulder, the shamed face hidden. “Who is this feller they call colonel, child?” she asked, gently.

“He owned—the house we lived in—in El Paso,” came the muffled explanation. “He’s rich, and—and very refined.”

“I know a place that’s full of jest such refined fellers,” muttered Huldah, angrily.

“Billy didn’t seem to love the baby as he—as—and Colonel Emerson is very fond of children—he’s devoted to my baby—or I thought he was. And he said that it was cause enough for me to leave Billy. And if I should leave him—if I should leave Billy—if I should get a divorce from him—he said—Colonel Emerson said——”

“Don’t tell me what he said, honey child,” urged Huldah. “What’d he do? Where’s your baby?”

Oh, then the poor little mother clung with strangling sobs to the stronger, older woman. “I’m so scared,” she whispered. “He got me all these nice things—ain’t my clothes awfully pretty?—and he promised we’d bring the baby with us. He says he’s taking me to his mother, and that I can stay there until I get my divorce—because, you know, Billy has treated me awfully mean, and he don’t care—Billy—he don’t care a thing on earth about me nor the baby any more.”
