NGAMI , the central point of an inland See also:

water See also:system of See also:South See also:Africa, once forming a Iake 20 M. See also:long and ro wide, but now little more than an expanse of reeds growing in a soft treacherous See also:soil, below which brackish water is found. It is cut by 2o2° S. and 23° E. Ngami is the lowest point of a large depression in the See also:plateau which comprises nine-tenths of Africa south of the See also:Zambezi. The See also:area which drains to it is bounded S. by the See also:basin of the See also:Orange, E. by the See also:Matabele hills, N. by the western affluents of the Zambezi. The greater See also:part of the Ngami water-system lies, however, N.W. of the See also:lake (which for convenience it may still be called) in the tableland of See also:Angola and See also:German South See also:West Africa. On the high plateau of Bihe, in the See also:hinterland of See also:Benguella. rise two large See also:rivers, the Okavango and the Kwito, which uniting discharged their See also:waters into Ngami. From the N.E. end of Ngami issued the Botletle or Zuga, a stream which runs S.E. and drains towards the Makarikari See also:marsh, from which there is no outlet. Although Ngami has dried up since 1890 the Okavango and its tributary the Kwito remain large rivers. The Okavango is known in its upper course as the Kubango. Its most remote source lies in about 1r° S. and 161° E. and its length is over 90o m. It flows first S. then S.E. and E. In about 18° S. and 2oz° E. it is joined on the See also:north See also:bank by the Kwito, a large navigable stream rising almost as far north as the Okavango.

Its See also:

general course is S.E., but between 15° and 17° S. it flows S. and even S.W. Below the Kwito confluence the Okavango, which is also joined by various streams from the S.W. (German territory), is a rapid stream with an See also:average breadth of over See also:loo yds., and generally navigable as far as the Popa falls, in 210 50' E. In the dry See also:season, the water-level is from 4to 20 ft. below the See also:banks, but these are overflowed during the rains. At this See also:period, See also:April-See also:June, some of the surplus water finds its way (in about r9° S.) by the Magwekwana to the Kwando or Linyanti (Zambezi system), to which, it is conjectured, the whole See also:body of water may have once flowed. Below the Magwekwana outlet the Okavango, now called the Taukhe or Tioghe, turns almost due S., enters a swampy See also:reed-covered See also:plain and is broken into several branches. In this region the effects of See also:desiccation are marked. Through the swamps the See also:river formerly entered Ngami. The last 20 M. of the old channel are now dry and devoted tc See also:grain crops. Above this point the waters of the Okavango arc diverted eastward through a channel called Tamalakane to the Botletle, the river which, as stated above, formerly flowed out of Ngami. The point of confluence is in about 20° S. 232° E., the Botletle above this point being merely a See also:succession of pools.

Below the junction the river See also:

bed is 150 to 200 yds. wide. The banks are 25 to 30 ft. high, and See also:form steep See also:white walls of See also:sand compacted with See also:lime, behind which the dark See also:green See also:forest rises. The stream is fringed with reeds harbouring countless water-See also:fowl. The Botletle, whose bed is about loo m. in length, loses itself in a system of See also:salt-pans—See also:round or See also:oval basins of varying See also:size sunk to a See also:depth of 30 to 45 ft. in the See also:sandstone, and often bounded by steep banks. The See also:outer pans are dry for a large part of the See also:year, the whole system being filled only at the height of the See also:flood-season in See also:August. The Botletle, which receives in addition the scanty waters of the See also:northern See also:Kalahari, at this season reaches the Makarikari marsh. This marsh, occupying the N.E. corner of See also:Bechuanaland, has also feeders from the Matabele hills in the direction of See also:Bulawayo. During the rains the marsh is converted into a large lake. Much of the water is lost by evaporation; much of it sinks into some subterranean See also:reservoir. The See also:evidence o1 travellers is conclusive that the See also:country around Ngami is drving up. The desiccation appears to be rapid. In 1849 when See also:David See also:Livingstone visited Ngami the lake though shallow was of considerable extent.

Later travellers reported progressive decrease in the size of the lake and in 1896 See also:

Sir F. D. See also:Lugard and Dr Siegfried Passarge found it dry. Dr Passarge was told by the natives that the cessation of the river's flow was caused, about 189o, by a blocking of the channel by thousands of rafts. Although the river system below the Magwekwana outlet of the Okavango is drying up, above that point there are long stretches of navigable water both on the Okavango and the Kwito, in all considerably over Imo m. The Popa falls are the last of a See also:series of six in a distance of 40 m., but none See also:present serious See also:engineering difficulties. The Magwekwana connexion with the Zambezi is a little over loo m. long, and for more than See also:half its course flows through a deep well-defined bed with a minimum width of no, yards. The fall to the Linyanti affluent of the Zambezi is only a few feet and the country presents no obstacles to the construction of artificial channels. Ngami is within the (See also:British) Bechuanaland See also:protectorate, about 5o m. E. of the frontier of German South-West Africa. The See also:district is the See also:home of the Batawana tribe of See also:Bechuana, with whom is stationed a See also:European See also:magistrate. The tribes living along the See also:lower Okavango are tributary to the Bechuana, and the blocking of the channel referred to was occasioned by their bringing to Ngami their See also:annual See also:tribute of See also:corn.

See BECHUANALAND and KALAHARI. An See also:

account of the Ngami district is given in See also:Die Kalahari by Dr Siegfried Passarge (See also:Berlin, 1904). Of See also:early books of travel consult C. J. Andersson's Lake Ngami (See also:London, 1856) and The Okavango River (London, 1861). NGAN-HUI (AN-IrwEl or GAN-HWLTY), an eastern See also:province of See also:China, which, together with Kiang-su and Kiang-si, forms the See also:vice-See also:royalty of Kiang-nan. It is bounded N. by Ho-nan, E. by Kiang-su and Cheh-kiang, S. by Kiang-si and W. by Hu-peh and Ho-nan. It covers an area of 48,461 sq. m., and contains a See also:population of 23,600,000. Its See also:principal See also:city is Ngan-kiing on the Yangtsze Kiang, besides which it See also:numbers seven prefectural cities. One district city, Ho-fei, is noted as having been the birthplace of Li Hungchang (1822-1901). The See also:southern half of the province, that portion south of the Yangtsze Kiang, forms part of the Nan-shan, or hilly See also:belt of the south-eastern provinces, and produces, besides See also:cotton, See also:coal and See also:iron ore, large quantities of green See also:tea. There are also considerable forest areas.

Nganhui is one of the most productive provinces of China. Over the whole of its southern portion tea is largely grown, notably in the districts of Hui-chow Fu, Tung-liu, Ta-tung and Wu-hu. The Yangtsze Kiang is the principal river of the province, and is of See also:

great importance for See also:foreign See also:commerce, supplying See also:direct water communication between some of the principal tea-growing districts and the neighbourhood of Hang-chow. The only other river of importance is the Hwai-ho (see CHINA: The Country). Wu-hu on the Yangtsze Kiang is the only open See also:port in this province. From this port a railway runs S.E. to Wen-chow—an open seaport in Cheh-kiang province.
