About sunset we stopped at a small shed on the banks of the Ukrina, where, seated among a group of Christian peasants, we regaled ourselves with black coffee which was being dispensed at the rate of about a farthing a small cup. Hard by, fixed over the Ukrina stream, was a water-mill for grinding corn, of the most primitive construction, an idea of which is best given by the accompanying diagram. These turbines are universal throughout Bosnia, and are to be also seen in Croatia. [Illustration: Plan of Turbine Mill.] The peasants here were mostly Vlachs, that is, they belonged to the Greek Church. The men wore red and black turbans, a flowing white linen tunic like the Croats, with a fringe of that coarse lace which we had noticed in Slavonia. A leathern belt wound several times round the waist served as a pocket for their smoking apparatus; their trousers were worn loose and expansive as the Croatian, sometimes close about the calf; their hair was sometimes plaited together behind, and sometimes hung down in two elf-locks—the crown of the head being shaven, as with the Turks. As to the women, they were dressed in light tunics and aprons, much as Croats and Slavonians, but their hair was often plaited like the men’s into a single pig-tail. On their head was a white kerchief arranged in a fashion peculiar to themselves, with a flower-like tassel at one side; and they usually wore in front of the two necessary aprons a superfluous black one with long fringe. Here is a Greek Christian girl that we saw at a well, and who graciously allowed us to slake our thirst from the bucket she had just drawn up. [Illustration: Bosnian Girl of the Possávina.] These Greek Church women wore blue embroidery to their dresses, but the Roman Catholics of this part, though dressing otherwise like the Greeks, distinguish themselves from their fellow-Christians by embroidering their clothes with red, while their men protest against a Universal Church by wearing tighter breeches than the Orthodox. It is hardly to be expected after this that they should call the founder of their faith by the same name; and, indeed, the Romanists call Christ ‘Krst,’ and themselves ‘Krisčiani,’ while the Greeks speak of ‘Hrist’ and of themselves as ‘Hrisčiani;’ so that H in Bosnia is a shibboleth. The Greek Bosnians use Cyrillian characters, and call themselves distinctively Serbs or Pravoslaves, that is, ‘the orthodox;’ the others look on the Cyrillian character as a snare of the devil, and, far from trying to claim fellowship with the people of Free Serbia, style themselves Latins—‘Latinski’—for it always seems to be a tendency of Romanists to thrust patriotic interests into the background.
