This region, occupying so large a portion of the African continent, "is a vast archipelago of oases, of which each presents an animated group of towns and villages. Around each is a large enclosure of fruit trees. The palm is the king of these plantations, not only from the elevation of its trunk, but from the value of its product, yet it does not exclude other species. The fig, the apricot, the peach and the vine mingle their foliage with the palm." The Algerine Sahara has lately been the object of a special work of Col. Daumas who intends completing the researches begun by Gen. Marey and the members of the scientific commission. He has made an excursion to the borders of the desert, and has collected much that is new and interesting in ethnology, particularly relating to the Tuarycks, a great division of the Berber race whose numerous tribes occupy all the western part of the great desert.[36] Among the interesting Ethnological facts which the late expeditions in this region have brought to light, is that of the existence of a white race, inhabiting the Aures mountains, (_mons Aurarius_) in the province of Constantine.[37] Dr. Guyon, of the French army of Africa, took advantage of an expedition sent out by General Bedeau to the Aures, to collect information about this people, to whom other travellers had referred. He describes them as having a white skin, blue eyes and flaxen hair. They are not found by themselves, but predominate more or less among various tribes. They hold a middle rank, and go but rarely with the Kabyles and the Arabs. They are lukewarm in observances of the Koran, on which account the Arabs esteem them less than the Kabyles. They are more numerous in the tribe of the Mouchaïas, who speak a language in which words of Teutonic origin have been recognized. In Constantine where they are numerous, they exercise the trades of butcher and baker. Late writers believe that they are the remains of the Vandals driven from the country by Belisarius. M. Bory de Saint Vincent in making some observations to the Academy of Sciences, on the paper of Dr. Guyon, exhibited portraits of individuals of this white race, which had been engraved for the Scientific Commission, and stated his belief that they were evidently of the northern Gothic and Vandal type.[38] In Northern Africa, an important discovery has lately been made of the ancient Libyan alphabet, by Mr. F. de Saulcy, member of the French Institute. This curious result has been produced, by a study of the bilingual inscription on the monument of Thugga, which is published in the first volume of the Transactions of the Ethnological Society of New York. The reading of the Phoenician part of this bilingual inscription having been established, the value of the Libyan or Numidian letters of the counter part, has been as clearly proved, as the hieroglyphic part of the Rosetta stone has been established, from a comparison with the Greek text of that bilingual inscription.
