''The Somalis are a fighting race and all go armed with spear, shield and short sword (and guns when they can get them).
During the rains incessant inter-tribal looting's of cattle take place. Among certain tribes those who have killed a man have the right to wear an ostrich-feather in their hair. They are great talkers, keenly sensitive to ridicule, and quick-tempered.
Women hold a degraded position among the Somalis-(wives being often looted with sheep), doing most of the hard work.
The Somalis love display; they are inordinately vain and avaricious; but they make loyal and trustworthy soldiers and are generally bright and intelligent.
The Somalis have very little political or social cohesion, and are divided into a multiplicity of 'reers' or 'fakidas' (tribes, clans).
Three main divisions, however, have been clearly determined, and these are important both on political grounds.
1) The 'Hashiya' (Abud's Asha), with two great subdivisions.
'Daroda,' with the powerful Mijertins, War-Sangeli, Dolbohanti and others; and Ishak, including the Gadibursi, Issa (Aissa), Habr-Wal, Habr-Tol, Habr-Yuni, Babibli, Bertiri.
All these claim descent from a member of the Hashim branch of the Quraish, who founded a powerful state in the Zeila district. All are Sunnis, and, although still speaking their Somali national tongue, betray a long infusion of Arab blood in their oval face, somewhat light skinned, and remarkably regular features.
Their domain comprises the whole of British Somaliland, and probably most of Italian Somaliland.
2) The Hawiya, with numerous sub-groups, such as the Habr-Jalet, Habr-Gader, Rer-Dollol, Daji, Karanle, Badbadan, Kunli, Bajimal and Ugass-Elmi; mostly fanatical Mohammedans forming the powerful Tarika sect, whose influence is felt throughout all the central and eastern parts of Somaliland.
The Hawiya domain compromises the Ogaden plateau and the region generally between the Nogal and Webi-Shabelle Rivers.
Here contact has been chiefly with the Eastern Oromo tribes.
3) The Rahanwin, with numerous but little known sub-groups, including, however, the powerful and warlike Abgals, Barawas, Gobrons, Tuni, Jidus, and Kalallas, occupy in part the region between the Webi-Shabelle and Juba, but chiefly the territory extending from the Juba to the Tana, where they have long been in contact, mostly hostile, with the Wa-Pokomo and other Bantu peoples of the British East Africa Protectorate.
Of all the Somali the Rahanwin betray the largest infusion of Negroid blood.
Of the outcast races the best known are the Midgan, Yebir, and Tomal. The Midgan, who are of slightly shorter stature than the average Somali, are the most numerous of these peoples. They are great hunters and use small poisoned arrows to bring down their game. The Yebir are noted for their leather work, and the Tomal are the blacksmiths of the Somali.
Prehistoric remains.-The discovery of flint implements of the same types as those found in Egypt, Mauritania, and Europe show Somaliland to have been inhabited by man in the Stone age. That the country was subsequently occupied by a more highly civilized people than the Somali of to-day is evidenced by the ruins which are found in various districts.
Many of these ruins are attributable to the Arabs, but older remains are traditionally ascribed to a people who were ''before the Oromos.''
Blocks of dressed stone overgrown by grass lie in regular formation; a series of parallel revetment walls on hills commanding passes exist, as do relics of ancient water-tanks.
This ancient civilization is supposed to have been swept away by Mohammedan conquerors; before that event the people, in the opinion of several travellers, professed a degraded form of Christianity, which they had acquired from their Abyssinian neighbors.
Of more recent origin are the ruins known as ''Taalla Galla'' (Galla graves). These are cairns of piled stones, each stone about the size of a mans head. The cairns are from 12 to 15 ft. high and about 8 years in diameter. Each is circular with a central depression.''
