Later, with Mrs. Marquand, Mrs. Aspinwall, Mrs. Astor, and Mrs. Hamilton Fish, and a hundred others, she had signed the call for the great mass-meeting; had acted on one of the subcommittees chosen from among the three thousand ladies gathered at the Institute; had served with Mrs. Schuyler on the board of the Central Relief Association; had been present at the inception of the Sanitary Commission and its adjunct, the Allotment Commission; had contributed to the Christian Commission, six thousand of whose delegates were destined to double the efficiency of the armies of the Union.

Then Sainte Ursula’s Sisterhood, organised for field as well as hospital service, demanded all her energies.  It was to be an emergency corps; she had hesitated to answer the call, hesitated to enroll for this rougher service, and, troubled, had sought counsel from Mr. Dodge and Mr. Bronson of the Allotment Commission, and from Dr. Agnew of the Sanitary Commission.

Dr. Agnew wrote to Dr. Benton: 

“Mrs. Paige is a very charming and very sweet little lady, excellently equipped by experience to take the field with Sainte Ursula’s Sisterhood, but self-distrustful and afraid of her own behaviour on a battle-field where the emergency corps might be under fire.  In this sort of woman I have every confidence.”

The next day Ailsa enrolled; arranged her household affairs so that she could answer any summons at a few hours’ notice; and went to bed dead tired, and slept badly, dreaming of dead men.  The morning sun found her pale and depressed.  She had decided to destroy Berkley’s letters.  She burned all, except one; then went to her class work.

Dr. Benton’s class was very busy that morning, experimenting on the doctor’s young assistant with bandages, ligatures, lint, and splints.  Letty, wearing only her underclothes, lay on the operating table, her cheek resting on her bared arm, watching Ailsa setting a supposed compound fracture of the leg, and, at intervals, quietly suggesting the proper methods.

Autumn sunshine poured through the windows gilding the soft gray garb of Sainte Ursula’s nursing sisterhood which all now wore on duty.

The girl on the table lay very still, now and then directing or gently criticising the well-intended operations on limb and body.  And after the allotted half hour had struck, she sat up, smiling at Ailsa, and, slipping to the floor, dressed rapidly, talking all the while in her pretty, gentle way about bandages and bones and fractures and dislocations.

A few minutes after she had completed dressing and was standing before the glass, smoothing the dark, silky masses of her hair, Dr. Benton arrived, absent-eyed, preoccupied at first, then in a fidgety humour which indicated something was about to happen.  It happened.

“Could any lady get ready in time to take the noon train for Washington?” he asked abruptly.

There was a startled silence; the call had come at last.
