Ida shrank back against the wall as if she had been struck, but when Lord John, who had made several futile attempts to separate her from her husband, came eagerly forward, she left Gregory to the chorus of enthusiasm and congratulation, and obeyed his directions. XIX Ida was in such high spirits during the luncheon that she managed to be brilliant and amusing within the limits of her expurgated vocabulary. Only Ora, who knew her so well, saw the sombre fire in the depths of her eyes, the sudden twist of her mouth at the corners, noted that her cheeks were crimson instead of their usual delicate coral, the occasional clenching of her hands. But she had little time to speculate upon the cause, for the large party were her guests, and, like any other Rocky Mountain hostess in the liquid month of June, she feared the sudden drenching of her tables. But the day remained fine, and the geologists, who ever since their arrival in Butte had evinced a remarkable indifference to geology as a topic for conversation, were as lively as the newspaper men, and deeply appreciative of the good looks and animated conversation of the four women who ate almost nothing in their efforts at mental subdivision. Ora had invited also her engineer and Professor Whalen, placing the latter as far from Ida as possible; but she saw that he was covertly watching the woman he must hate. Ida had thrown him a careless nod when they met by the tables in the grove; and he had returned it with a bow of surpassing dignity. Gregory, now that the men of science and of the press had served his purpose, was eager to be rid of them, and excused himself when the luncheon was half over, on the plea that he was his own manager and needed at the mine. He disappeared into the Primo shaft house, as he often took that short cut to his own shaft, and Mowbray, who had been silent, for Gregory affected his buoyant spirits unaccountably, moved his chair up beside Ida and endeavoured to divert her mind from the general to the specific. But she snubbed him and he relapsed into gloom. On the train, however, when she saw that Whalen, who was on his way to Helena to apply for his patent, was watching her, she flirted pointedly with the handsome Englishman. The guests were to leave Butte on the seven o’clock train, which, fortunately for the strain that all were beginning to feel, was only half an hour late. When it had pulled out and Ida had waved her last farewell, she walked in silence to her car, and intimated with a curt nod that Mowbray might take the seat beside her. “But tell Ben where you want to go,” she said, “for I can’t ask you to dine with me tonight.” Mowbray told the chauffeur to drop him at the Club and then asked his lady, whose animation had dropped to zero, if anything had happened to annoy her, or if she were merely worn out.
