BITTER WATERS 193 somnolent moments and might have been bolder with impunity, for my shot-gun had now gone finally out of action and all our efforts to put it right were unavailing. This was something of a tragedy as we could scarcely hope to get any more small birds though I continued to note their occurrence, and even tried from time to time to shoot them with my pocket pistol. As I sat alone on a dune top commanding the hollow a rifle shot rang out, echoing and re-echoing from slope to slope. I saw a fox standing stock-still on the rock below. For a moment it stood there before flight into the sands beyond, where I followed it with my glasses as Farraj and Al Aqfa pursued. The beast was obviously wounded—the bullet had gone through its abdomen—and rapidly the bitch overhauled it. Then among the bushes came the end, and Farraj came back triumphant with his trophy, which proved to be a Fennec or Desert Fox of the new subspecies1 collected last year by Mr. Thomas. Having surveyed the scene sufficiently I went straight down the steep soft slope towards the pit, whose geological formation I examined while the tents were being pitched and the camels driven forth to the pastures. About 50 feet above the floor of the depression an intermittent stratum of friable greyish sandstone appeared from under the heaped- up sands. Downwards it shelved to a rock-floor of similar formation, some acres in extent and curving round the actual well area in an imposing semicircular cliff of 10 or 12 feet, whose horns penetrated and lost themselves in the steep surrounding sand slopes. In this area I found a few shell fragments of freshwater2 origin, but otherwise nothing but the characteristic odds and ends of old Badawin camps—horns of the Rim gazelle, cartridge cases, fragments of leather and the like. But three fragments of stone picked up by me in this locality have proved to be parts of a single small stony meteorite.3 1 Arabia Felix, p. 340. I brought back three specimens in all, which have been provisionally labelled Cynalopex sp. by Captain J. G, Dollman of the British Museum. 2 Melanoides tuberculatd—see Appendix. z See Appendix. N
