After traversing this terrible desert of fifty miles--a barrier to all general and commercial intercourse, which we should think impassable, however it might be overcome by a small party of bold and hardy men, well led, furnished with every supply, water excepted, which could sustain them through its horrors, (and which yet, through that single want, had nearly perished)--they persued a long and dlifficult march through a dreary country, scantily peopled, dotted with robber clans, and exhibiting impediments of all kinds in the knavery and villany of the native authorities; until they reached the borders of Abyssinia. We had by no means been aware that volcanoes had made so large a share of this portion of Africa. The whole border seems to be volcanic, and to retain in its blasted and broken surface, evidence of its having been, in remote ages, perhaps in the earliest, the scene of most intense and general volcanic action. In Major Harris's animated description--"singular and interesting indeed is the wild scenery in the vicinity of the treacherous oasis of Sultelli. A field of extinct volcanic cones, vomited out of the entrails of the earth, and each encircled by a black belt of vitrified lava, environs it on three sides; and of these Mount Abida, three thousand feet in height, whose cup, enveloped in clouds, stretches some two and a half miles in _diameter_, would seem to be the parent. Beyond, the still loftier crater of Aiulloo, the ancient landmark of the now-decayed empire of Ethiopia, is visible in dim perspective; and, looming hazily in the extreme distance, is the great blue Abyssinian range." In any part of Africa a river of tolerable magnitude is an object of the most anxious interest; and the approach to the Hawash, the boundary river of the kingdom of Shoa, was looked to with eager speculation. At length the height was reached from which was obtained "an exhilarating prospect over the dark, lone valley of the long looked-for Hawash. The course of the river was marked by a dense belt of trees and verdure, stretching towards the base of the great mountain range, of which the cloud-capped cone, which frowns over the capital of Shoa, forms the most conspicuous feature." The mission now began to exalt:--"Though still far distant, the ultimate destination of the embassy appeared almost to have been gained, and none had an idea of the length of time that must elapse before his foot should press the soil of Ankober." A day of intense heat was as usual followed by a heavy fall of rain, which, owing to the unaccommodating arrangement of striking the tents at sunset, thoroughly drenched the whole party.
