er they were all dry. Beyond is the Wady Chizolen,
overlooked by a mountain that rises abruptly to the height of two
thousand feet. Then comes the valley of Eghellal, with its rivulet, and
beyond swell the famous mountains of the Baghzem. The worthy Doctor
seems to have been too much occupied in collecting geographical data to
preserve many picturesque facts by the way. On the third day he encamped
at Tiggedah, where numerous species of trees and bushes tufted the
valley, which was clothed also, near the margin of its streams, with
grass as fresh and green as any in Europe. At that time, however, the
place, with the exception of the cooing of wild doves and the cry of a
solitary antelope, seemed perfectly unvisited by man. Afterwards, it was
found full of flocks and herds, and enlivened by the encampment of a
salt-caravan, with a string of young camels bound for Aghadez. The tribe
to whom the valley belongs are nomadic, and shift from one place to
another, as their fancies and necessities suggest. Amidst the trees,
however, may be seen a small mosque, built of stone and roofed with
palm-trees.

[6] See the papers read before the Geographical Society, in
January and March 1851. It appears to me that Mr. A.
Petermann slightly depresses the importance of the part
played by Mr. Richardson in this mission. However, this may
arise from the fact that the communications on which his
paper was founded were all from his German friends. It is
not necessary to be grudging of notice to any of the three
enterprising gentlemen who undertook this arduous journey;
but we must always remember who planned the Mission, and
who directed it with consummate prudence as long as life
and strength lasted. In Mr. Richardson's MS. an outline is
given of Dr. Barth's journey, and I therefore insert it,
with corrections and additions, from the papers just
alluded to.--ED.

This agreeable place prefaces the still more luxuriant scenery of
Asadah, where the vegetation is so rich, and the path so shut up by
branches, that it is difficult to keep on the camel's back. What a
contrast to the naked deserts of Ghat! It was from between the rich
foliage of this valley that Dr. Barth obtained his first glimpses of the
majestic mountain-chain of Dogem, estimated to attain the height of
between four and five thousand feet. It is the loftiest range in Aheer.
