When I had come to comprehend their habits I more or less adapted my life to theirs in hunting them. I sought the hills, toward dusk, with rifle and blanket, to pick my way steadily up into the mountain-tops, sometimes sighting sheep on the way; then sleeping in some sheltered nook on the summit, till the quest was renewed at the first hint of dawn. The wild ruggedness of the country is unbelievable until one is actually in amongst the endless range of valleys and slopes that are thick with the disordered rocks and gigantic boulders that make up the crags and corries and cairns which meet one on every side. The hunter requires to be nimble as a cat to leap and step quietly in such surroundings, and _noiselessness is essential_ if the keen-sensed Arui is to be successfully approached. Wherefore one must go barefooted or with soft-soled shoes, and in consequence feet and shins suffer many bruises and jars on the hard, cruel rocks, particularly in travelling when it is very dark. I had no serious accident in those wild hills; only a few minor ones. I once lost the nail of a big toe through a stone giving way and turning over to pin my foot beneath it. On another occasion, through my attention being distracted by movement below, I stepped into space, and had an ugly fall, which was not lightened by my efforts to save my precious rifle. But miraculously no bones were broken, though knees, arms, hands, and face bled so freely that anyone might have thought I was a proper ambulance case. I was particularly anxious to secure good examples of the Arui of Aïr, which had not been collected by anyone before (which, as a new subspecies, has since been named _Ammotragus lervia angusi_ (Rothsch.) in my honour). Hence I spent many nights in the lone mountains and laid my head to rest in some wild, eerie spots, unknown to the eyes of men. It was a wonderful experience to be all night high up in the great mountains, and to watch the final lights of eve, and dawn. Indeed, I came to know these hills in another complexion. From afar I had always thought them frowning and black, while now I discovered them soft smoke blue in the mornings, and shades of mauve when touched with the late evening sun. Dawn is the most favourable hour for hunting. It is then that the Arui ascend the steep and bouldered mountain slopes from wild corries where they have been browsing overnight, on a scattering of hardy shrubs and wiry grass, to seek dark resting-place for the day among great cairns near the summits where the air remains cool and shade complete. And that is the time when the hunter has a chance to intercept them on the way to their lairs. [Illustration: AN AARDVARK OR ANT-BEAR]
