The same was true of the blue serge suit she wore. Nothing can be imagined more innocuous than a suit of blue serge, embellished with narrow black braid. Miss Finch could have worn one of the identical cut and material and it would have looked as if it had been designed for her. Yet on Agatha the blue serge was alluring. It captured the eye as though striped with scarlet.

Mrs. Van Horne, a stout, middle-aged woman who occupied a swivel chair at a businesslike desk, watched the operation of adjusting the black toque and rubbed her nose with a flourish indicating mental perturbation. It had occurred to her that Agatha was a somewhat colorful person for the task to which she had been assigned, that she looked undeniably youthful for so responsible an errand, that some one grayer in tone and of an aspect radiating propriety and decorum, would have been better fitted for the duty in hand. Mrs. Van Horne looked at the clock, saw it lacked but thirty-seven minutes to train time, and brushed aside her scruples. It was now too late to change.

"You are sure you feel equal to taking charge of the four, Miss Kent?" she said, more for the reassuring effect of Agatha's self-confident answer than because she had the slightest doubt what that answer would be.

Agatha turned a vivacious face. "I'm really looking forward to the trip. It'll be such fun."

"I should hardly use that term to describe traveling in charge of four children," observed Mrs. Van Horne, with a grim smile. "And one of them a teething baby. You will naturally attract a good deal of attention."

"Not a bit," said Agatha briskly.

"You think not?"

"Every one will take it for granted that I am a young mother, coming home with my little family to visit grandpa and grandma."

Mrs. Van Horne's brow cleared. As the representative of a serious-minded organization, with an established reputation for prudence and sagacity, she had been accusing herself of indiscretion in entrusting this important commission to a young woman of such butterfly aspect, even though in self-defense she insisted that of her assistants, Miss Kent was easily the most resourceful and capable. Agatha's suggestion brought relief. Without doubt she was right. The traveling public would assume her to be a matron of extraordinarily youthful appearance. No one would question the discretion of the head of the Hamilton Orphanage for committing four children to the care of one who, whatever her capacity, looked a fly-away girl.
