the Turanians had so rapidly been absorbed that Prince Omortag bestowed Slav names upon his sons, and this complete mingling of the radically different peoples was assisted, says the Professor, by the fact that those Bulgarian hordes in the days before they crossed the Danube were already partly mixed with Slavs, since they had been wandering for decades to the north of the Danube, around Bessarabia, in which country the Slavs were members of the same Slovene race as those whom they were afterwards to meet. So thoroughly were the original Bulgars submerged in the Slavs that when their sons set out from the district between Varna, Rustchuk and the Balkans, proceeding west and south, they met with no resistance from the unorganized Slavs of Mœsia and Thrace, owing to the circumstance that these latter did not feel that the new arrivals were strangers. In fact, says the Professor, there are in the present Bulgarian people far fewer and far fainter traces of the original Bulgars than there are of the old Thracians, as also of the Greeks and of the different people who in the course of the great migrations probably left here and there some stragglers. Sir Charles Eliot says of the Bulgars that "though not originally Slavs they have been completely Slavized, and all the ties arising from language, religion and politics connect them with the Slavs and not with Turkey or even Hungary." Professor Cvijić, by the way, who in 1920 received the Patron's Medal of the Royal Geographical Society for his researches into Balkan ethnology, regards the author of _Turkey in Europe_ as a greater authority in this field than himself.... It is not easy, away from Montenegro and a few remote valleys, to find communities on the Balkan mainland that are altogether free from alien blood; Turks have come and gone, Crusaders of all nationalities have passed this way, with their hangers-on, here was the road from Europe to Asia, and here amid the ruin of empires lay much that was worth gathering. No doubt the Serbs, whose land was not so much a thoroughfare, have in their veins some Illyrian and other, but on the whole much less non-Slav blood than the Bulgars; still, when we consider some subsequent invasions of Bulgaria, we must ascertain how far they spread. For example, the Kumani who arrived in the thirteenth century were, according to Leon Cahun,[13] Turks of the Kiptchak nation, speaking a pure Turkish dialect; they--that is to say, the Gagaous who are supposed to be their descendants--are now Christians, they speak modern Turkish and inhabit the shores of the Black Sea and the region of Adrianople; they have kept much to themselves and are recognizable by their dark faces, large teeth and hirsute appearance. There are people who assert that all Bulgars have a physical divergence from other Yugoslavs, but, except if they happened to come across one of these Gagaous or some such person, it appears more likely that they saw what they went out to see.
