The Gudabirsi tribe received them from the Girhi in lieu of blood-money: beyond this watercourse, the ground belongs to the Rer Yunis Jibril, a powerful clan of the Habr Awal, and the hills are thickly studded with thorn-fence and kraal.
Without returning the salutations of the Bedouins, who loudly summoned us to stop and give them the news, we trotted forwards in search of a deserted sheep-fold. At sunset we passed, upon an eminence on our left, the ruins of an ancient settlement, called after its patron Saint, Ao Barhe: and both sides of the mountain road were flanked by tracts of prairie-land, beautifully purpling in the evening air. After a ride of thirty-five miles, we arrived at a large fold, where, by removing the inner thorn-fences, we found fresh grass for our starving beasts. The night was raw and windy, and thick mists deepened into a drizzle, which did not quench our thirst, but easily drenched the saddle cloths, our only bedding. In one sense, however, the foul weather was propitious to us. Our track might easily have been followed by some enterprising son of Yunis Jibril; these tracts of thorny bush are favourite places for cattle lifting; moreover the fire was kept blazing all night, yet our mules were not stolen.
We shook off our slumbers before dawn on the 27th. I remarked near our resting-place, one of those detached heaps of rock, common enough in the Somali country: at one extremity a huge block projects upwards, and suggests the idea of a gigantic canine tooth. The Donkey declared that the summit still bears traces of building, and related the legend connected with Moga Medir.7 There, in times of old, dwelt a Galla maiden whose eye could distinguish a plundering party at the distance of five days’ march.
The enemies of her tribe, after sustaining heavy losses, hit upon the expedient of an attack, not en chemise, but with their heads muffled in bundles of hay. When Moga, the maiden, informed her sire and clan that a prairie was on its way towards the hill, they deemed her mad; the manoeuvre succeeded, and the unhappy seer lost her life. The legend interested me by its wide diffusion. The history of Zarka, the blue-eyed witch of the Jadis tribe, who seized Yemamah by her gramarye, and our Scotch tale of Birnam wood’s march, are Asiatic and European facsimiles of African “Moga’s Tooth.”
