He went away, leaving Ruth with a thought that did not make it any easier for her to smile. She saw people all day long coming into the building and seeking out the cashier’s desk, where Mrs. Mantel sat, to hand over contributions of money to the Red Cross. If only each brought a dollar there should be a large sum added to the local treasury each day.

There was no way of checking up these payments. The money passed through the hands of the lady in black and only by her accounts on the day ledger and a system of card index taken from that ledger by Mr. Legrand, who worked as her assistant, could the record be found of the moneys contributed to the Red Cross at this station.

Ruth Fielding was not naturally of a suspicious disposition; but the honesty of Mrs. Mantel and the real interest of that woman in the cause were still keenly questioned in Ruth’s mind.

She wondered if Mr. Mayo knew who the woman really was. Was her story of widowhood, and of her former business experience in New Orleans strictly according to facts? What might be learned about the woman in black if inquiry was made in that Southern city?

Yet at times Ruth would have felt condemned for her suspicions had it not been for the daily sight of Mrs. Mantel’s hard smile and her black, glittering eyes.

“Snakes’ eyes,” thought the girl of the Red Mill. “Quite as bright and quite as malevolent. Mrs. Mantel certainly does not love me, despite her soft words and sweet smile.”

There was some stir in the headquarters at last regarding a large draft of Red Cross workers to make up another expeditionary force to France. Two full hospital units were going and a base supply unit as well. Altogether several hundred men and women would sail in a month’s time for the other side.

Ruth’s heart beat quicker at the thought. Was there a prospect for her to go over in some capacity with this quota?

Most of the candidates for all departments of the expeditionary force were trained in the work they were to do. It was ridiculous to hope for an appointment in the hospital force. No nurse among them all had served less than two years in a hospital, and many of them had served three and four.

She asked Mr. Mayo what billets there were open in the supply unit; but the chief did not know. The State had supplied few workers as yet who had been sent abroad; Robinsburg, up to this time, none at all.
