Valuable salt is obtained from the pits at Dolnja Tuzla, and the southern part of Herzegovina yields asphalt and lignite.
The other, a narrowgauge line, crosses the Save at Bosna Brod, and follows the Bosna to Serajevo, throwing out branches eastward beyond Dolnja Tuzla, and westward to Jajce and Bugojno.
Serajevo, with 41,543 inhabitants in 1895, is the capital of the combined provinces, and other important places are Mostar (17,010), the capital of Herzegovina, Banjaluka (14,812), Dolnja Tuzla (11,034), Travnik (6626), Livno (5273), Visoko(5000), Foca (4217), Jajce (3929) and Trebinje (2966).
The patriarch of Constantinople is the nominal head of the Orthodox priesthood; but by an arrangement concluded in 1879, his authority was delegated to the Austrian emperor, in exchange for a revenue equal to the tribute previously paid by the clergy of the provinces; and his nominations for the metropolitanate of Serajevo, and the bishoprics of Dolnja Tuzla, Banjaluka and Mostar require the imperial assent.
Two years later, the imperial troops reached Dolnja Tuzla, and retired with 3000 Roman Catholic emigrants.
