Within about a hundred yards of its base the bush ceased, and there was that distance of open sand to cross before I could get cover again; so I lay and watched, but there was no sign of a living being anywhere, and I scooted across and got among the big granite boulders, where I felt perfectly safe. Working cautiously upwards, I got about half-way to the top when, to my astonishment, I came upon a well-beaten track where horses had been taken up and down, and whilst I was still staring open-mouthed at the fresh spoors, I found that I was within a yard of a rough, loopholed schanz of rock, overlooking and commanding our territory! I knew our men had never been in the hill, and that it must have been made by the Germans, and I stood stock-still, expecting rifles to show through the loopholes at any moment. However, there was neither sound nor sign, and I crept on more carefully than ever, finding that the whole place had been strengthened with these schanzes, which were on British territory, and which commanded British territory for miles. At the top, surrounded by titanic boulders the size of a four-roomed cottage, there was a Hat space about 40 feet square, where there was every sign of recent occupation--well-trampled paths, freshly broken stones, tools, and the still smouldering embers of a fire; whilst between the huge boulders schanzes had been built or were nearing completion. There had been a large number of men in the hill but recently, and they would undoubtedly return--indeed, there were probably some of them in the hill then! I crept to the edge overlooking German territory, and could see the top of the police post, with the German flag flying, about 500 yards away westward, and a number of men and horses passing between a gap in that direction towards the water-pits, which, however, were not visible. I had but three films in my camera, and I took them as quickly as possible, for I felt sure there was a sentry there somewhere; and sure enough, as I peered over the rocks down the western slope, I saw a solitary soldier coming up between the rocks, turning and motioning as though to others behind him. And I got down and into the bush like a scared klip-springer; for these men, who had violated our territory, and were strengthening a position which commanded every approach for miles, were scarcely likely to show much ceremony to an Englishman found with a camera in the middle of their schanzes!
