ALGERIA, a country in North Africa under French domin ion, bounded west by Morocco, north by the Mediterranean, east by Tunisia, and south by Italian Libya and French West Africa. North Algeria has an area of 2o7,915sq.km. between 37° and 34° N. lat. and 2° i o' and 8° 5o' E. long. ; it is i , i ookm. long east to west, and 300-40o north to south, and so has the form of a narrow rectangle. The Saharan areas adjacent to Algeria have formed a separate administrative unit, the Southern Territories, since 1902; their area is 2,129,400sq.km., more than ten times that of North Algeria. The southernmost point in these Southern Territories, Tin Zaouaten, 20° N. lat., is 1,75okm. from Algiers, while from the ocean to Tripolitania is about r,800km. This immense area is, however, almost empty, and poor in resources at present utilizable, and it is a mere adjunct of the northern or true Algeria.
Archaean and Palaeozoic rocks occupy little space save near the coast east of Algiers where they are accompanied by volcanic ex trusions. Secondary rocks, usually calcareous or marly, form the main skeleton of the Atlas chains from the sea to the Sahara. Ter tiary rocks are also highly developed and include limestones, marls, sandstones, clays. Those of Oligocene or later date include fluviatile and lacustrine, as well as marine, deposits.
The Algerian chains show two series of foldings, the Tell Atlas and the Saharan or pre-Saharan Atlas, separated by a zone which narrows from west to east and is hardly folded at all.
In Algeria, west of the meridian of Algiers and Medea, the lit toral massifs have a large tertiary depression on their south side; then comes the axial chain of the Tell Atlas with tertiary deposits to the south again. The Tlemsen-Saida massif forms the third step and belongs climatically to the Tell but structurally to the main block. Beyond this to the south is the region of steppes with tertiary basins, of which the shotts fill the remnants. Finally, the Saharan Atlas forms a ridge fronting the desert. East of Al giers the zones are much less distinct. The Kabylian Tell is much higher and rougher than the Tell of Oran, and ends in the Edough massif at Bone, the end of the Tell Atlas. Beyond this, the Saha ran Atlas with its north-eastward trend reaches the coast sepa rates the Algerian plateau from the Tunisian Sahel, with its tabular structure and its numerous small chains in the eastern part of the department of Constantine.
The North Sahara is built very simply. The Ahaggar, or cen tral Tuareg massif, is made up of crystalline rocks surmounted by extinct volcanoes (Ilamane, 2,200 metres). Around it are the sandstone plateaus called the Tazili of the Azjer and the Muydir Ahmet. A great aureole of calcareous Cretaceous plateaus (Tade mayt, El-Golea, M'zab) separates the northward sloping Ighar ghar basin from that of the Saoura which slopes southward. The first has the oases of Warqla, Wad-Rir and the Zibans, the second those of Gurara, Tuat and Tidikelt. Vast dunes, the eastern and western Erg, complete the symmetry.
A zone from Dellys to the Tunisian frontier with coastal mas sifs gets more thpn 800mm. of rain (Bougie 1,036mm.). A zone along the coast from Tenes to Dellys and thence inland south of the previous one gets 600-800mm. (Algiers, 728mm.). The Oran coast west of Tenes and the remainder of the Tell get 400-600mm. (Constantine, 589mm.). The high plateaus and the pre-Saharan Atlas get 2oo-400mm., save on a few heights (Jelfa, 38omm.). The Saharan slope of the Atlas gets less than 200MM., that is small, irregular and accidental rainfall (Biskra, 143 mm.).
Most Algerian streams are periodic, with the rains, and many diminish from their sources downwards and may lose themselves in inland basins or in the Sahara. The Cheliff is the chief river, over 7ookm. long, with an outflow varying from 3o-15 cubic metres during the rains to a few hundred litres in the dry season. The lacustrine hollows, shotts or sebkhas, are occupied by salt deposits where evaporation has reduced them. On the Saharan slopes oasis irrigation and hot sands absorb the streams as soon as they leave the mountains. The Zousfana, helped by the Guir, occasionally reaches Foum-el-Kheneg. Wadi Mia and Wadi Ighar ghar are dead rivers; fossils in fact.
There are few peculiar animals. The lion has recently become extinct here, the panther and hyena are still found in the woods and a monkey (Pithecus innuus) occurs. Jackal and wild boar are very abundant and there are various antelopes (gazelles). The Saharan fauna is highly specialized; horned vipers and scorpions are fairly common.
Population. In 1931 the population was 6,553;451, with a municipal population of 6,469,896. Of this total 574,618 live in the Southern Territories giving a density of less than one per sq. km. This figure rises to 28 in the north. The indigenous element is Berber with Arab admixture physically assimilated. Physically diverse types are seen everywhere and their origins are little known. Arab invasions have had little influence on racial types but have spread Islam and Arabic language ; Berber dialects, how ever, survive in remote spots in Kabylia, Aures and Saharan oases and among the Tuaregs. The Mozabites are not an orthodox Muslim people but belong to the Ibadite or Kharejite schism. In digenous peoples number in all 5,632,663 including 565,987 in the Southern Territories, and they have increased rapidly under French rule, from less than 2,000,000 in 183o and some 3,2oo,000 in 1886. The increase now exceeds 400,000 in ten years or a dou bling in 40 years. Three-quarters of the indigenous population live in the Tell and because of security and rain, mountain lands are more peopled than the plains (contrast Europe).
The urban element in this population comprises about 6%, much less therefore than in Tunisia or Morocco, and only 3o lo calities have more than 3,000 agglomerated natives in each. Out side the towns the greatest contrast is between sedentary culti vators living in houses aggregated into villages (thaddert) sur rounded by gardens and planted woods, and nomad shepherds living in tents grouped into douars and moving about with their sheep and goats. There are also demi-nomads, living in gourbis more settled than the nomads, less fixed than the house-dwellers. A tendency exists to limit movements of nomads.
Europeans number 920,788, of whom 8,631 are in the Southern Territories. Nearly all live on the coast and in the Tell, largely in towns, though there is an important rural element. The distri bution contrasts with that of the natives for the department of Oran has 367,o9o, that of Alger 347,206 and that of Constantine 197,861. In the department of Oran Europeans occupy nearly all the cultivable land; in that of Alger they are numerous around Algiers, in the Sahel and in the Mitija ; in that of Constan tine they are sporadic.
From 1830 to 1856 the number of Europeans grew from 600 to 169,000 by immigration, but in that period deaths of Europeans were more numerous than births. Since 1856 births have been in excess, and there were 311,000 Europeans in 1876, 477,00o in 1891 and 752,000 in 1911. The increase is about ioo,000 souls in ten years. Of the Europeans in 1926 there were 657,64i French, chiefly from southern departments (Corsica, Bouches-du-Rhone, Gard, Herault, Pyrenees Orientales), and since 1896 more of the French have been Algerian born than French born. Spaniards from Murcia, Valencia, Alicante and the Balearics are numerous in the department of Oran. Italians from Sicily and Calabria occur especially in the department of Constantine. Maltese are to be found in most towns. Other Europeans are not numerous. Up to 1889 French and non-French European elements were about equal. To understand subsequent changes one must remember that many Frenchmen in Oran have married Spanish women, that any child born in Algeria is accounted as naturalized French unless he claims other nationality in the year of his majority, and that Jews, some of ancient settlement, others coming from Spain in the i6th and i7th centuries, were naturalized en bloc by the Cremieu decree (187o). An Algerian people is obviously forming itself and it is becoming purposeless, as well as almost impossible, to distinguish French born from naturalized citizens.
Towns. Algiers, the capital had (1931) a total population of 257,122, with a municipal population of 246,o61 (169,257 Euro peans and 76,804 natives). Oran had a municipal population of 157,981 (125,866 Europeans), Constantine 99,595 (48,15o Euro peans), Bone 65,653 (37,231 Europeans), Bel-Abbes 42,671 (27,653 Europeans), Philippeville 46,399 (23,173 Europeans), Mascara 30,122 (13,403 Europeans), Mostaganem 26,839 (12, 776 Europeans), Tlemsen 44,094 (11,653 Europeans), Setif 3 2 ,3 6 2 (9,907 Europeans). The oases of the Sahara often have an urban character, e.g., Biskra (22,273), Tidikelt-Hoggar (12,694), Ghar daia 01,415), El-Oued (10,616), Laghwat (6,264)• Administration. Algeria is neither a colony in the usual sense, nor a simple aggregate of French departments; it has not complete autonomy, yet it ir not entirely assimilated to France. A governor-general of Algeria, appointed by the minister of the interior, is helped by a general secretary and a council. Algeria is represented in the French parliament by three deputies for each of its three departments and by senators. It also has two local assemblies. The financial delegations are an assembly on which colonials elect 24, non-colonials 24, and Muslim natives 21 mem bers, with a special Kabyle section in the last group. The Con seil superieur is made up of elected and official elements. These two assemblies vote the local budget instituted by law in 19oo to permit Algeria to raise revenue in the usual ways, including ex cise and monopolies, and leaving Algeria responsible for its debts, administration, public works and so on, subject to control and veto of the French Government. France pays the military and naval expenses but Algeria paid a war contribution of 6% of its budget. That budget is now about i,000 million francs, and has usually shown a surplus. Fiscal schemes are based on those of France, and taxes are the smile for Europeans and natives.
Northern Algeria has three departments (Oran, Alger, Constan tine), divided into arrondissements which include communes de plein exercice with administration on French lines, and communes mixtes with natives in large numbers. The latter divisions are often large and are under special administrators, each has a munic ipal council helped by native sheikhs, caids or aghas. Natives elect representatives on all local assemblies.
The Southern Territories, with a separate budget, were created by decree of Dec. 24, 19o2; they are named Ain-Sefra (capital same name), Ghardaia (capital Laghwat), Tugurt (capital same name) and the Oases (capital Warqla). At the head of each is a military commandant acting under the governor-general, and each is divided into circles, annexes, "communes mixtes" and na tive communes. Old Arab taxes have been continued and order is guarded by meharist camel corps, forming the Saharan com panies.
Algiers has a university with faculties of law, medicine, science and letters which have produced much research in science, history, archaeology, linguistics, law and medicine, especially relative to North Africa. Primary and secondary schools for Europeans are on French lines. Most natives do not go beyond the primary school but there are higher schools, called Medersas, for Muslim functionaries. The knowledge and use of French has spread very widely among the natives.
Free grants of land, with obligatory residence, have been the rule save under the Second Empire. Four modes of transfer are recognized by the decree of Sept. 13, 1904, namely, sale at a fixed price at public office, the usual method, sale by auction under public control, sale by private treaty and free concession. A decree of Sept. 9, 1924, has lengthened the period of obligatory residence from ten to 20 years, and the period during which the lands may be transferred only to French colonists from 20 to 4o years. The proportion of colonization land reserved to Algerians has been in creased from one-third to one-half. Of 2,400,000 hectares of colonization land 7oo,000 have passed into European hands by private purchase, the remainder being occupied by official coloni zation. There are 600 European agricultural centres, 230,000 agriculturists, 90,00o proprietors. Official colonization has nearly come to an end, and can do little more than develop communi cations and build new hamlets at spots reached by them.
Stockraising is important with eight to nine million sheep, four million goats, one million cattle, 200,000 horses, 300,00o asses, 150,000 mules and i5o,000 camels, the camel being used as a pack animal on the steppes and more especially for riding in the Sahara. The sheep suffer from drought, cold and parasitic dis eases; about one million are exported every year, chiefly for meat. Wool production is small, less than 18,000 tons.
Forests occupy three million hectares, but much of this is mere scrub. Fires and trespass of flocks are the great enemies of the forests. 200,000 quintals of cork are produced. Alfa covers four million hectares and gives 1,5oo,000 quintals for paper-pulp. The dwarf-palm yields 500,000 quintals of fibre.
The ports of Algiers (2,642,000 tons cargo and 2,560,000 tons shipping), Oran (2,215,00o tons cargo and 3,308,00o tons ship ping), Bone (1,272,00o tons), Philippeville (294,000 tons) and Bougie (250,000 tons) are fully equipped. Secondary ports in clude Nemours, Beni-Saf, Mostaganem, Cherchell, Jijelli, Collo, and La Calle. By a law of 1889 only French ships may trade between France and Algeria.
