Martini speaks, apparently from personal knowledge, of the splendour of the city, as regards both its public edifices and its site, sloping gradually up from the banks of the River Wei, so as to exhibit its walls and palaces at one view like the interior of an amphitheatre. West of the city was a sort of Water Park, enclosed by a wall 30 _li_ in circumference, full of lakes, tanks, and canals from the Wei, and within this park were seven fine palaces and a variety of theatres and other places of public diversion. To the south-east of the city was an artificial lake with palaces, gardens, park, etc., originally formed by the Emperor Hiaowu (B.C. 100), and to the south of the city was another considerable lake called _Fan_. This may be the Fanchan Lake, beside which Rashid says that Ananda, the son of Mangalai, built his palace. The adjoining districts were the seat of a large Musulman population, which in 1861–1862 [and again in 1895 (See _Wellby, Tibet_, ch. xxv.)—H. C.] rose in revolt against the Chinese authority, and for a time was successful in resisting it. The capital itself held out, though invested for two years; the rebels having no artillery. The movement originated at Hwachau, some 60 miles east of Si-ngan fu, now totally destroyed. But the chief seat of the Mahomedans is a place which they call _Salar_, identified with Hochau in Kansuh, about 70 miles south-west of Lanchau-fu, the capital of that province. [Mr. Rockhill (_Land of the Lamas_, p. 40) writes: “Colonel Yule, quoting a Russian work, has it that the word Salar is used to designate Ho-chou, but this is not absolutely accurate. Prjevalsky (_Mongolia_, II. 149) makes the following complicated statement: ‘The Karatangutans outnumber the Mongols in Koko-nor, but their chief habitations are near the sources of the Yellow River, where they are called Salirs; they profess the Mohammedan religion, and have rebelled against China.’ I will only remark here that the Salar have absolutely no connection with the so-called Kara-tangutans, who are Tibetans. In a note by Archimandrite Palladius, in the same work (II. 70), he attempts to show a connection between the Salar and a colony of Mohammedans who settled in Western Kan-Suh in the last century, but the _Ming shih_ (History of the Ming Dynasty) already makes mention of the Salar, remnants of various Turkish tribes (_Hsi-ch’iang_) who had settled in the districts of Ho-chou, Huang-chou, T’ao-chou, and Min-chou, and who were a source of endless trouble to the Empire. (See _Wei Yuen, Sheng-wu-ki_, vii. 35; also _Huang ch’ing shih kung t’u_, v. 7.) The Russian traveller, Potanin, found the Salar living in twenty-four villages, near Hsün-hua t’ing, on the south bank of the Yellow River. (See _Proc. R. G. S._ ix. 234.) The Annals of the Ming Dynasty (_Ming Shíh_, ch. 330) say that An-ting wei,
