The defiles are occasionally blocked by masses of rock swept down by the mountain torrents, and presenting serious obstacles to the local trafific. The most remark- able ravines occur along the eastern edge of the plateau, where the total fissure exceeds 6,500 feet, measured from the summit of the degas down to the sea-level. Nowhere else can a more convincing proof be observed of the erosive action of running waters. The two walls of certain gorges, rising nearly vertically within a few feet of each other to a height of some hundreds of feet, represent an erosion of hard rock amounting to at least ten thousand five hundred million cubic feet. Nevertheless, the waters have regulated the fall of the channel, which averages not more than one in forty yards. This incline is easily ascended, but several of the defiles remain blocked for months together by the mountain torrents ; every year new paths have to be formed across the débris, while some have had to be entirely abandoned. The route to Kumaili, through which the English army marched to the Abyssinian plateau, had probably not been occupied by a military force since 9âAF.
