It happened that the Silver Foxes were that morning practising in first aid, and as soon as Mr. Ellsworth could gather from the frightened girl that her mother was in real need, he rushed “Doc” Carson, the first-aid boy, and Roy off to the rescue, instructing the other members of the patrol to follow scout pace.

Water was brought and Mrs. Temple quickly revived. Her head had been slightly cut as she fell, and this Carson bandaged skilfully. She was still too weak to walk, however, and the boys improvised a litter in which she was carefully borne back to camp, Mary walking at her side.

The Ravens, meanwhile, under Mr. Ellsworth’s direction, had prepared a sort of couch of fir boughs. Onto this they helped Mrs. Temple and the scoutmaster sat down beside her.

Perhaps it was not entirely by chance that he had instructed the two patrols to go through their signalling maneuvers at a little distance, so that they should not disturb the invalid, but yet in full view and near enough so that she might follow the course of the proceedings if she cared to. Mary had a thousand questions to ask as to the meaning of the various signals, and the kind scoutmaster answered them all patiently, finally summoning Eddie Ingram to show her about the camp and explain all its mysteries. Then, seeing that Mrs. Temple showed some interest in the maneuvers, the guileful Mr. Ellsworth proceeded to explain their practical value and the good uses to which the scout “stunts” were often put, tactfully pointing out the change that had taken place in Tom Slade, who at this moment was bashfully showing Mary how to blow whistle signals on a small bottle.

Mrs. Temple, however, showed but a courteous interest, and feeling that her husband would be alarmed at her long absence she called to Mary and insisted upon returning home immediately, despite Mr. Ellsworth’s urgent invitation that she stay and share the scouts’ luncheon.

The Silver Fox patrol was ordered to escort the ladies home, and with this ample bodyguard they returned to Five Oaks, the boys laughingly contesting for the honor of walking with Miss Mary—­all save Tom, who lingered somewhat shamefacedly in the rear.

As they walked up the gravel path through the spacious lawn, it was evident that something was wrong. One of the servants was in the portecochere, wringing her hands, and the stoical Japanese valet stood near her, calm and unsmiling.

The unusual sight of the uniformed scouts did not seem to ruffle him at all.

Carl, the gardener, was craning his neck to look up and down the road from the window of the library, a room which he would never have dared to enter save on a very urgent matter.

“Where is Mr. Temple?” Mrs. Temple asked. “I have had quite an adventure.”
