Just what she wanted to say to him she did not know. She still resented bitterly his mistrust of her, and what she regarded as his interference with her liberty, but she had no intention of letting matters rest as they were. She and Dan must fight the matter out to some satisfactory conclusion.

Then came the news of his marriage, shattering every hope and shaking the very foundation of her being. From her earliest remembrance Dan had been the most dependable factor in her existence. Whirlwind enthusiasms for other things and other people had caught her up from time to time, but she always came back to Dan, as one comes back to solid earth after a flight in an aeroplane.

In her first weeks of chagrin and mortification she had sought refuge in thoughts of Mac. She had slept with his unanswered letters under her pillow and clung to the memory of his ardent eyes, his gay laughter, the touch of his lips on her hands and cheeks. Had Mac come home that Christmas, her doom would have been sealed. The light by which she steered had suddenly gone out, and she could no longer distinguish the warning coast lights from the harbor lights of home.

But Mac had not come at Christmas, neither had he come in the summer, and Nance's emotional storm was succeeded by an equally intolerable calm. Back and forth from factory to boarding home she trudged day by day, and on Sunday she divided her wages with Mrs. Snawdor, on the condition that she should have a vote in the management of family affairs. By this plan Lobelia and the twins were kept at school, and Mr. Snawdor's feeble efforts at decent living were staunchly upheld.

When the epidemic broke out in Calvary Alley, and Mrs. Snawdor signaled for help, Nance responded to the cry with positive enthusiasm. Here was something stimulating at last. There was immediate work to be done, and she was the one to do it.

As she hurried up the steps of Number One, she found young Dr. Isaac
Lavinski superintending the construction of a temporary door.

"You can't come in here!" he called to her, peremptorily. "We're in quarantine. I've got everybody out I can. But enough people have been exposed to it already to spread the disease all over the city. Three more cases to-night. Mrs. Smelts' symptoms are very suspicious. Dr. Adair is coming himself at nine o'clock to give instructions. It's going to be a tussle all right!"

Nance looked at him in amazement. He spoke with more enthusiasm than he had ever shown in the whole course of his life. His narrow, sallow face was full of keen excitement. Little old Ike, who had hidden under the bed in the old days whenever a fight was going on, was facing death with the eagerness of a valiant soldier on the eve of his first battle.

"I'm going to help you, Ike!" Nance cried instantly. "I've come to stay 'til it's over."

But Isaac barred the way.
