of the Finster-aarhorn, Schreckhorn, and Grimsel, in the canton of Bern; and at the Handeck in the valley of Hash forms a magnificent water-fall of above 150 feet in height. It then falls successively into the lakes Brienz and Thun, and, emerging from the latter, flows through the cantons of Bern, Soleure, and Aargau, emptying itself into the Rhine, opposite Waldshut, after a course of about 170 miles. Its principal tributary streams are the Kander, Saane, and Thiele on the left, and the Emmen, Surin, Aa, Reuss, and Limmat, on the right. On its banks are situated Unterseen, Thun, Bern, Soleure or Solothurn, Aarburg, and Aarau. The Aar is a beautiful silvery river, abounding in fish, and is navigable from the Rhine as far as the Lake of Thun. Several small rivers in Germany have the same name.
AARAU, the chief town of the canton of Aargau in Switzerland, is situated at the foot of the Jura mountains, on the right bank of the river Aar, 41 miles N.E. of Bern. It is well built, and contains a town-hall, barracks, several small museums, and a library rich in histories of Switzerland. There is a cannon foundry at Aarau, and among the principal manufactures are silk, cotton, and leather; also cutlery and mathematical instruments, which are held in great repute. The slopes of the neighbouring mountains are partially covered with vines, and the vicinity of the town is attractive. About ten miles distant along the right bank of the Aar are the famous baths of Schinznach. Population, 5449.
AARD-VARK (earth-pig), an animal very common in South Africa, measuring upwards of three feet in length, and having a general resemblance to a short-legged pig. It feeds on ants, and is of nocturnal habits, and very timid and harmless. Its flesh is used as food, and when suitably preserved is considered a delicacy. The animal is the only known species of its genus (Orycteropus), and belongs to the order Edentata of the mammalia. The same prefix Aard appears in the name of the Aard-wolf (Proteles Lalandii), a rare animal found in Caffraria, which is said to partake of the characters of the dog and civet. See Mammalia.
AARGAU (French, Argovie), one of the cantons of Switzerland, derives its name from the river which flows through it, Aar-gau being the province or district of the Aar. It is bounded on the north by the Rhine, which divides it from the duchy of Baden, on the east by Zurich and Zug, on the south by Lucerne, and on the west by Bern, Soleure or Solothurn, and Basel. It has an area of 50212 square miles. By the census of 1870, the number of inhabitants was 198,873, showing an increase during the preceding ten years of 4665. Aargau stands sixth among the Swiss cantons in density of population, having 395 inhabitants to the square mile. The statistics of 1870 show that of the inhabitants 107,703 were Protestants, 89,180 Catholics, and 1541 Jews. German is the language almost universally spoken.
Aargau is the least mountainous canton of Switzerland. It forms part of a great table-land to the north of the Alps and the east of the Jura, having a general elevation of from 1200 to 1500 feet. The hills do not rise to any greater height than 1800 feet above this table-land, or 3000 feet above the level of the sea. The surface of the country is beautifully diversified, undulating tracts and well-wooded hills alternating with fertile valleys watered by the Aar and its numerous tributaries, and by the rivulets which flow northward into the Rhine. Although moist and variable, the climate is milder than in most parts of Switzerland.
The minerals of Aargau are unimportant, but remarkable palæontological remains are found in its rocks. The soil to the left of the Aar is a stiff clay, but to the right it is light and productive. Agriculture is in an advanced state, and great attention is given to the rearing of cattle. There are many vineyards, and much fruit is grown. The canton is distinguished by its industry and its generally diffused prosperity. Many of the inhabitants are employed in the fishings on the Aar, and in the navigation of the river. In the villages and towns there are considerable manufactures of cotton goods, silk, and linen. The chief exports are cattle, hides, cheese, timber, raw cotton, yarn, cotton cloths, silk, machinery, and wooden wares; and the imports include wheat, wine, salt, leather, and iron. The most important towns are Aarau, Baden, Zofingen, and Laufenburg, and there are mineral springs at Baden, Schinznach, Leerau, and Niederweil. The Swiss Junction Railway crosses the Rhine near Waldshut, and runs south through the canton to Turgi, whence one line proceeds S.E. to Zurich, and another S.W. to Aarau and Olben.
Until 1798, Aargau formed part of the canton of Bern, but when the Helvetic Republic was proclaimed, it was erected into a separate canton. In 1803 it received a considerable accession of territory, in virtue of the arrangement under which the French evacuated Switzerland. According to the law whereby the cantons are represented in the National Council by one member for every 20,000 inhabitants, Aargau returns ten representatives to that assembly. The internal government is vested in a legislative council elected by the body of the people, while a smaller council of seven members is chosen by the larger body for the general administration of affairs. The resources of Aargau are stated to amount to about a million sterling; its revenue in 1867 was nearly £82,000, and the expenditure slightly greater. There is a public debt of about ₤40,000. The canton is divided into eleven districts, and these again are subdivided into forty-eight circles. There is a court of law for each district, and a superior court for the whole canton, to which cases involving sums above 160 francs can be appealed. Education is compulsory; but in the Roman Catholic districts the law is not strictly enforced. By improved schools and other appliances great progress has been made in education within the last thirty or forty years.
AARHUUS, a city and seaport of Denmark, situated on the Cattegat, in lat. 56° 9′ N., long. 10° 12′ E. It is the chief town of a fertile district of the same name, one of the subdivisions of Jutland. The cathedral of Aarhuus is a Gothic structure, and the largest church in Denmark. The town also contains a lyceum, museum, and library. Aarhuus is a place of extensive trade. It has a good and safe harbour, has regular steam communication with Copenhagen, and is connected by rail with Viborg and the interior of the country. Agricultural produce, spirits, leather, and gloves are exported, and there are sugar refineries, and manufactures of wool, cotton, and tobacco. Population (1870), 15,020.
AARON, the first high-priest of the Jews, eldest son of Amram and Jochebed, of the tribe of Levi, and brother of Moses and Miriam. When Moses was commissioned to conduct the Israelites from Egypt to Canaan, Aaron was appointed to assist him, principally, it would appear, on account of his possessing, in a high degree, persuasive readiness of speech. On the occasion of Moses' absence in Mount Sinai (to which he had gone up to receive the tables of the law), the Israelites, regarding Aaron as their leader, clamorously demanded that he should provide them with a visible symbolic image of their God for worship. He weakly complied with the demand, and out of the ornaments of gold contributed for the purpose cast the figure of a calf, this form being doubtless chosen in recollection of the idols of Egypt. In obedience to instructions given by God to Moses, Aaron was appointed high-priest; his sons and descendants, priests; and his tribe was set apart as the sacerdotal caste. The office of high-priest was held by Aaron for nearly forty years, till the time of his
