"I want some!" Catherine dug into her purse.

"Aren't they stale?" Bill watched her fasten the creamy, buff-pink buds to her coat.

"Probably. But they look fresh now." Catherine swung into step again. Queer, how that occasional little side glance of Bill's gave assent to her mood, dipped into it, recognized it, without a word.

"I suppose," she said, as they rounded the corner of Amsterdam, "that I can't stay on this level. It's too high. But I've just reached it to-day. Assurance, and a long sight into what I can do."

"There's always, unfortunately, another day." Bill frowned slightly. "Another mood. But you seem to have hit a fair wind. Henrietta told me that Miss Kelly was panning out well."

"Yes." The view ahead, of the dipping, climbing avenue, with its familiar shops, its familiar clatter of the cobblestones, was sharp as a background of relief against which to-day stood out. "I know what I feel like, Bill. If you want to know."

"I do. Always."
