A light ladder was made by which to climb up into the roof; drinking-water was taken up in buckets and hidden there; a window-frame in the east wing was prepared so that the iron bars could be withdrawn; and we made certain, by going through a list, that our packs contained all that we had decided to take. The latter were then unpacked and they and their contents placed in two boxes, each of which had a false bottom. Here were concealed our most incriminating and at the same time our most precious aids to escape: our maps, helio-mirrors, fezes, and compasses. The boxes were then locked, strongly bound with rope, and labelled very appropriately, "Trek Stores." For the work on hand that night the occasion was an excellent one. Every one was busy packing, having left this unpleasant duty till the carts actually arrived. There was a lot of noise being made--to wit, a blend of singing and sawing; and when at 1 A.M. we could at last go to bed, there was still much activity around us. Next morning we showed ourselves as much as possible, and took care to find an opportunity of talking to the two camp interpreters. It was conceivable that they might take our names in the barracks as usual each morning, and the commandant, being satisfied that every one was present, might omit to call roll when the move actually took place; or alternately, in the excitement of the moment, there might be no roll-call whatsoever. On one or other of these possibilities depended the success of the modified scheme, which stipulated that until the carts were definitely on the move we were not to hide ourselves in the roof. Should the party go off without a roll-call, we were allowed to leave ourselves behind. If, on the other hand, roll was called, we had to turn up for it. This explains the necessity for the two boxes of "Trek Stores": if we were left behind, these could be quickly taken up into the roof; and if roll should be called, we could hastily, and without losing our valuable escape outfit, join the carts, carrying two boxes apparently containing food only. After loading up our own carts with the rest of our kit in case the scheme miscarried, we took these boxes into the mess-room at the S.E. corner of the barracks; and as the time of departure drew near, went there ourselves and sat round a few bits of bread and an empty jam-pot. Our excellent friend H---- promised to come and warn us should there be a call over. From the windows facing south could be seen the Angora road, and this we watched eagerly. The barracks were quite quiet. After many minutes a loaded cart appeared on the road followed by another. Our hopes began to rise. The one-in-a-thousand chance might yet come off. There were more carts moving on the road now, but to our disappointment they suddenly stopped.
