Such a man's knowledge in physics, chemistry and biology, though less precise, is often wider than that of the individual specialist. His friendship with Theophilus Caldegard, begun at Cambridge, had lasted and grown stronger with the years.

On the evening of his brother's arrival he dressed for dinner later than was his custom. His bath had filled him with a boyish desire to whistle and sing; and now, as he tied his bow and felt the silk-lined comfort of his dinner-jacket, he heard with a throb of elation the soft sound of a skirt go by his door.

He murmured as he followed:

"—lentus in umbra
Formosam resonare doces Amaryllida silvas."

But before he reached the stairhead, all other sounds were drowned by shouts of laughter from the billiard-room—good laughter and familiar; but the smile left his face and his pace slackened. He was, perhaps, too old to wake the echoes, and Dick's laugh, he thought, was infectious as the plague.

In the wide, comfortable hall used instead of the drawing-room which Bellamy hated, he found Amaryllis smiling with a sparkle in her eyes, as if she too had been laughing.

"Did you hear them?" she asked.

Randal nodded.

"Father hasn't laughed like that for years—billiards!" she said. "Your brother is just telling him shocking stories, Sir Randal."

"How d'you know?" he asked.
