She had clung with peculiar tenacity to the hallucination that she still had youthful charm of face and figure. As she stared, it seemed as though the sand was sliding a little faster from beneath her feet. She shoved the loose knot of hair to its place and straightened herself, growing hot at the realization that she had betrayed to Essie Tisdale something of her consternation. She turned upon her fiercely-- "Look here, Ess, if you want to be friends with me, and have my influence to get you out of this mess, you'd better change your tactics." "Haven't I yet made it clear to you that I care no more for your friendship than for your enmity? Do you imagine that you can frighten liking, or force respect after the occasion which we both remember?" "There's one thing I can do--I can make Crowheart too hot to hold you!" Her grip on herself was going fast. Essie Tisdale stood up and, folding her arms, drew herself to her slim height while she looked at her in contemptuous silence. "I know there is no low thing to which you would not stoop to make good your boast. You make me think of a viper that has exhausted its venom. You have the disposition to strike, but you no longer have the power." "You think not? And why?

The woman sprang from her chair and walked to her with the crouching swiftness of a preying animal. She grasped Essie Tisdale's wrist in a grip which left its imprint for hours after. "How dare you!" Essie Tisdale raised her chin higher. "How dare I?" She smiled in the infuriated woman's face. "It takes no courage for me to oppose you now. When I was a biscuit-shooter here, as you lost no opportunity to remind me, you loomed large! That time has gone by. Crowheart will know you some day as I know you. Your name will be a byword in every saloon and bunk-house in the country!" "I'll _kill_ you!" The tense fingers were curved like steel hooks as she sprang for Essie Tisdale's slender throat, but even as the girl shoved her chair between them a masculine voice called "Esther" and a rap came upon the door. Doctor Harpe's arms dropped to her side and she clutched handfuls of her skirt as she struggled for self-control. Essie Tisdale walked swiftly to the door and threw it wide. The towering stranger stood in the corridor looking in amazement from one woman to the other. The girl turned and said with careful distinctness:
