Besides minerals, Bulgaria is extremely rich in mineral springs—the one at Banki, seventeen kilometres from Sofia, being about to be exploited this year, when a very handsome bath establishment and hotel are to be constructed. The source is situated in the valley beneath the Lubin mountain, and an automobile service is to be established with Sofia. This spring gives 1200 litres a minute, and has been pronounced by a number of first-class authorities in Germany and France to be a water almost unexcelled in Europe. Other springs abound all over the country, and so important are they, indeed, that the Government have issued a large coloured map of them. In Sofia itself, close to the old mosque, are well-known sulphur baths. There is a project for building a bath establishment, but to do so it would mean the pulling down of the mosque in question. The Turks would not object so much if a new mosque could be built, but it seems that the difficulties of construction are very great, so for the present the matter remains in abeyance. In the whole of Bulgaria over two hundred thermal and mineral springs are known, and they are situated in eighty different districts. The department of Sofia alone contains twenty-three, the warmest being at Dolna-Banja. The more important of the others are at Kniajevo, Gorva, Banja, and Pantcherevo. Then there are the renowned warm springs at Verschetz, in the department of Vratza, while in the department of Plovdiv (Philippopoli) there are more than forty springs, the principal of them being at Hissar. This, perhaps the most reputed in all the Orient, is situated in the valley of Tchepino, in the centre of the Rhodopes Mountains. At Lidji, near Bourgas, and at Sliven, there are establishments on the latest modern principle. Another which is being actively exploited is the waters of Meritchteri, in Stara-Zagora, which are declared by analysts to be quite equal to those of Carlsbad, and which are believed to have a great future before them. Dr. Ernst Hintz, of Wiesbaden, has written a book upon these particular waters, and has given exhaustive analyses.

Again, to encourage intending pioneers of new branches of industry, it is interesting to note that the industries in actual existence are making great progress. The numerous spinning mills and cloth factories in Eastern Roumelia have been enlarged, while the Varna Cotton Mill, whose headquarters are in Manchester, employs nearly seven hundred hands, and in 1905 paid a dividend of 10 per cent.
