“The ‘Aoul,’ as the Somalis call this Antelope, is almost ubiquitous in Somaliland. I have seen it within a few hours of Bulhar and Berbera on the maritime plain, whilst in 1896 we observed herds of it on the prairies to the south of the Elmas Mountains. Once in the mountains, whether in the ranges of the Gadabürsi country or of the Golis, you lose it and do not find it again, unless it be in some interlying plain, till you reach the region of the Haud. On the great prairies of the Haud I have seen an astonishing number of great herds from a single point of view. When travelling with Mr. E. N. Buxton and Mr. A. E. Leatham we first came on to the great Marar Prairie these Gazelles were seen in incredible quantities, and not having been hunted by even the Midgans (who devoted their time to pursuing the Oryx with their dogs and poisoned arrows) I found them astonishingly tame, so much so that after securing two or three specimens I never had the heart to betray their confidence, and have often walked past them in the thin bush that lines the northern edge of the plain within 20 paces, and on some occasions so near that I could almost have touched them with a long stick. At such times they have just lifted their heads till I had passed, and on looking back they had resumed feeding within a minute. I mention this as it is so very much in contrast with my experience when crossing the Toyoo Plain to the east in December 1896, when, though there were vast numbers of them, they were most extraordinarily wild and went off full gallop if you came within 400 yards of them. This was no doubt the result of having been shot at by English shikaris, who often take this route into Ogaden. On the Ogaden side of the Haud we found them frequently both in the long dhur grass, the home of the Dibatag (_Ammodorcas clarkei_), and also in open glades in the regular bush. When we were west of Milmil we came across these Gazelles occasionally till we reached the neighbourhood of the Tug Sulul; but I do not remember seeing them again in the more broken country that lies west of this Tug, and which continues practically hilly right up to the mountains of Bourka. From what I have been able to observe of the habits of this Antelope, I should think the traveller might expect to find it in any part of this corner of Africa where there are grass plains or where the bush is level and not too thick. It seems to thrive as well at sea-level as on the Haud at an elevation of 5000 feet.
