Most of this work was done before dinner, and the men had two hours' rest. After that tapes were brought out and the lines of a trench marked off, six feet from the hedge all round, and when that was done the men began to dig it out, five feet wide, one foot and a foot and a half deep, throwing the soil out on the hedge side, flattening it down and making it as firm as they could, so that if exposed to heavy fire the men might find protection, since the prickly walls, though difficult for men to struggle through, would not stop bullets. And so a good day's work ended, and the night sentries were posted between the trench and the hedge. There was no alarm that night. The next morning the camels were taken outside the zereba and watered at the large well, from which also a supply was drawn for the company; and it sufficed for all, evidently a valuable spring. That day the trench was completed, deepened a little, but not much, as it would not do for the defenders to be too low behind the hedge, and a small watch-tower commenced in the centre of the square. Some quaint, distorted trees were found at a little distance, and from one of these enough timber was got for the erection contemplated. There was a flat rock which formed a foundation for it, and a rustic-looking affair, something like a summer-house, was raised some twelve feet from the rock it stood on, which was already six feet from the level plain. From this elevation an extensive view could be obtained. On the third day a balcony was made round the top of the watch-tower, the sides of which were composed of logs, which it was reckoned would be bulletproof. A few good marksmen might, without being exposed, do considerable execution from this. It also had a roof fixed over it, and the look-out man had thus a protection from the sun. The saddles, with all cases and packages, were arranged to form an inner court of the zereba, within which were the camels, and when they were lying down they were very well protected. Hump, who of course had followed his company, took great interest in all these proceedings, and when the men were at work he stood with his head on one side watching them critically, and from the expression of his face, and the vibration of his tail, it was gathered that on the whole he approved. Captain Reece, who commanded the company, did not, as a matter of fact, much expect an attack, but he thought it only right to be prepared in case one were made, and being a man of an ingenious turn of mind, who, when a boy at Harton, was known as the "Dodger," he felt a special delight in constructing devices. On being ordered off on his present duty, he had gone to a friend in the Royal Engineers and begged a good bit of gun-cotton, carried for blasting purposes, and with this he proposed to make a mine, an electric battery and a coil of wire forming part of his baggage. There was a group of boulders two hundred yards off, which was certain to be taken
