The very day upon which her probationary period came to an end and, with a smile on her lips, a song in her heart, she placed the cherished cap upon her gold-brown curls, there came, from the heart of the swiftly piled up, lowering clouds, the blinding flash which shattered the peace of the world and started the overwhelming conflagration into the seething, bloody-tongued vortex into which nation after nation was sucked irresistibly. The world had become the plaything of the Gods of Wrath.

Black days passed, shuddering things of horror to Rose, when she had time to allow her mind to dwell upon them, and her keen imagination to picture the atrocities which the fiend was committing upon the helpless babies of Belgium and France.

Then, in answer to the cries and lamentations from overseas, the banner of the Red Cross was shaken forth anew, like a holy standard, and, like crusaders of old, doctors and nurses flocked beneath it for the battle. From her own hospital home went physicians and graduate nurses to dedicate themselves afresh to service. The call reached and wrung the heart of Rose. She could not go as a nurse, she knew; yet the need was so great that it seemed to her that somehow she must answer; but she resolutely closed her ears to it and fixed her eyes the more steadfastly upon the rocky, shut-in path which she had set forth to climb.

It was a raw, bleak evening in late November when she made her final resolve. At noon Donald had met her in one of the corridors and stopped to speak with her. His face, she thought afterwards, had appeared unusually serious and determined, even for him, as he said, "This is your afternoon and evening off duty, isn't it, Rose? I want to talk with you, if you haven't made any other plans."

As it chanced, she had been eagerly anticipating a visit to the theatre with Miss Merriman, who was home for a few days between cases; but something about his manner caused her to tell a white lie without hesitation.

"Good," he said. "I'll call for you in my car and take you to Ethel's for dinner. Be ready at six o'clock."

All the rest of the day Donald's presence had been strangely close to her, and she found herself wondering what it portended; but not until the pleasant family meal was over, and he was taking her home, did she learn.

When they came out of the house they found a baby blizzard sending the first snow of the season, as light and dry as tiny particles of down, whirling and eddying through the broad street. As Rose stood in surprise at the top of the brownstone steps, a dry vagrant, left from one of the trees which was tossing its gaunt arms protestingly, came tumbling down to become stem-entangled in her hair. With a laugh, she dashed for the motor car and, when she had sprung inside it, she was panting a little, for the thieving wind had taken advantage of her lips being open in laughter to steal away her breath, so that Donald was sensible of her quickened heart beats as she leaned against him while his big but deft fingers removed the leaf almost tenderly from its imprisoning mesh.

"Doctor Bentley would make a pretty speech about getting caught in my hair," challenged Rose with a teasing pout.

The next instant she drew quickly back, for Donald's arms were almost about her. He as quickly recovered himself, with the words, "But you can't expect pretty speeches from a brother."
