“Excuse me,” he said, quickly. “Miss Burke, this is my friend, Miss Arthur.” Then, not quite sure if this was a satisfactory introduction, he added, “Jessie, this is my friend, Mary.” Jessie’s training could not fail in any emergency. “Miss Burke,” she said, and smiled with perfect politeness. But Mary said nothing, and the strained look did not leave her face. In the first excitement she had almost failed to notice this stranger; but now she stared, and realisation grew upon her. Here was a girl, beautiful with a kind of beauty hardly to be conceived of in a mining-camp; reserved, yet obviously expensive--even in a mackintosh and rubber-shoes. Mary was used to the expensiveness of Mrs. O’Callahan, but here was a new kind of expensiveness, subtle and compelling, strangely unconscious. And she laid claim to Joe Smith, the miner’s buddy! She called him by a name hitherto unknown to his North Valley associates! It needed no word from Little Jerry to guide Mary’s instinct; she knew in a flash that here was the “other girl.” Mary was seized with sudden acute consciousness of the blue calico dress, patched at the shoulder and stained with grease-spots; of her hands, big and rough with hard labour; of her feet, clad in shoes worn sideways at the heel, and threatening to break out at the toes. And as for Jessie, she too had the woman’s instinct; she too saw a girl who was beautiful, with a kind of beauty of which she did not approve, but which she could not deny--the beauty of robust health, of abounding animal energy. Jessie was not unaware of the nature of her own charms, having been carefully educated to conserve them; nor did she fail to make note of the other girl’s handicaps--the patched and greasy dress, the big rough hands, the shoes worn sideways. But even so, she realised that “Red Mary” had a quality which she lacked--that beside this wild rose of a mining-camp, she, Jessie Arthur, might possibly seem a garden flower, fragile and insipid. She had seen Hal lay his hand upon Mary’s arm, and heard her speak to him. She called him Joe! And a sudden fear had leaped into Jessie’s heart.
