 For him there was safety in the direction which the talk had taken. His emphasis might come from feelings more personal than those science roused in him, but it was disguised, and naturally he found it easy to expound and explain. Nevertheless, when he saw Katharine among the orchids, her beauty strangely emphasized by the fantastic plants, which seemed to peer and gape at her from striped hoods and fleshy throats, his ardour for botany waned, and a more complex feeling replaced it. She fell silent. The orchids seemed to suggest absorbing reflections. In defiance of the rules she stretched her ungloved hand and touched one. The sight of the rubies upon her finger affected him so disagreeably that he started and turned away. But next moment he controlled himself; he looked at her taking in one strange shape after another with the contemplative, considering gaze of a person who sees not exactly what is before him, but gropes in regions that he beyond it. The far-away look entirely lacked self-consciousness. Denham doubted whether she remembered his presence. He could recall himself, of course, by a word or a movement—but why? She was happier thus. She needed nothing that he could give her. And for him too, perhaps, it was best to keep aloof, only to know that she existed, to preserve what he already had—perfect, remote, and unbroken. Further, her still look, standing among the orchids in that hot atmosphere, strangely illustrated some scene that he had imagined in his room at home. The sight, mingling with his recollection, kept him silent when the door was shut and they were walking on again.

But though she did not speak, Katharine had an uneasy sense that silence on her part was selfishness. It was selfish of her to continue, as she wished to do, a discussion of subjects not remotely connected with any human beings. She roused herself to consider their exact position upon the turbulent map of the emotions.
