"My flying column of scouts is over sixty strong, picked men and wonderfully brave," he said. "They are all in khaki and scour the country, doing the enemy incalculable harm, but they would be of more service to the commandos if they had better horses. Our horses are worn-out and underfed, their life is very hard, and it is imperative that we should have them reinforced. Now, we have heard that there are many magnificent horses kept at Skinner's Court, remounts kept in good condition for the special use of officers. Those horses we must have, and we have come to get all the information we can about the strength of the guards at Skinner's Court. For this I require van der Westhuizen's assistance."

Hansie felt a thrill of excitement.

The adventure was very much to her taste, and she remembered with delight that first successful raid on British stables. She wished she could supply the desired information. To steal the enemy's best horses seemed to her an enterprise worth toiling for, for there would probably be little or no bloodshed connected with it and, if successful, the reward would be very great.

But she felt assured that the adventure could not be in more capable, more trustworthy hands than in those of the silent van der Westhuizen.

When van der Westhuizen arrived, he and the Captain were closeted together in the bedroom for nearly an hour, and then he departed as silently as he had come, but Hansie had observed the look of steadfast determination on his face, and was satisfied.

Very unlike the previous visit was this, the last sojourn of the Secret Service men at Harmony.

There was no entertaining of shoals of trusted friends, no lying about under the trees, no sociable gathering of strawberries.

The men were not allowed to leave their bedroom during the day, but remained in safe proximity to the place of refuge under the floor, where their belongings lay buried.

Of the many plans devised by Mrs. van Warmelo for the safety of her guests, the following was decided upon as being the most ingenious:

A large bath was brought into her bedroom and half-filled with soapy water, bath-towels, sponges, and other toilet requisites being placed near by in readiness for use. In the event of a raid, Mrs. van Warmelo (if she had time to do so) would rush into the room, locking the door on the inside, while her daughter (if she had the presence of mind and kept cool enough) informed the police that her mother was having a bath. Thus time would be gained to enable the men to creep into their hiding-place.
