On that 23rd we started from Mahaber, going due west, and following for eight miles longer the charming valley of Ain. Afterwards, we diverged to the left, going in a south-west direction, until we reached the province of Barka; when again our route lay west by north, until we came to Zaga. From this point to Kassala the general direction is west by south. [Footnote: The distance from Mahaber to Adart on the frontier of Barka is about fifty miles; from Adart to Kassala about 130 miles.] From Mahaber to Adart the road is very pleasant; for several days we continually ascended, and the more we advanced into the mountainous region the more agreeable and pleasant did we feel it, and we enjoyed the sight of splendid and luxuriant vegetation.
On the 25th we crossed the Anseba, a large river flowing from the high lands of Bogos, Hamasien, and Mensa, and joining the river Barka at Tjab. [Footnote: Tjab, lat. 17 10', long. 37 15'.]
We spent a pleasant day in the beautiful Anseba valley, but aware of the danger of remaining after sunset near its flowery but malarious banks, we pitched our tent on a rising ground at some distance, and the next morning proceeded to Haboob, the highest point we had to gain before descending into the Barka through the difficult pass of Lookum. After this abrupt descent of more than 2,000 feet, the roads generally slope towards the low land of Barka.
From Ain to Haboob [Footnote: The Anseba, at the point we crossed, is about 4,000 feet above the level of the sea; Haboob about 4,500.] the country is well wooded, and watered by innumerable small streams. The soil is formed of the detritus of the volcanic rocks, specially of feldspar; pumice abounds in the ravines. The channels of the rivulets are the only roads for the traveller. This mountain chain is, on the whole, a pleasant spot, more delightful for the reason that it rises between the arid shores of the Red Sea and the flat, hot, and level plains of the Soudan. The province of Barka is a boundless prairie, about 2,500 feet above the level of the sea, covered at the time of our journey with half-dried grass some five or six feet high, and dotted here and there with small woods of stunted mimosas.
