30. – The Ethnological Map by the Bulgarian Professors (1915).

This map too is a Bulgarian one. It shows the extent of the Bulgarian people on the peninsula before the Balkan war of 1912. During this war and afterwards, certain ethnological changes have taken place in Macedonia and Thracia. This map is elaborated by Dr. A. Ischirkoff, Professor of Geography at Sofia University, with the assistance of four other professors. Ischirkoff himself, drew the ethnological map of the Bulgarian Kingdom in its old boundaries (until the year 1913) according to official statistics; Professor Dr. Miletitsch – that of Thracia; Professor Jordan Ivanoff – that of Macedonia; Professor Dr. S. Romansky – that of the Dobrudja; and Professor Dr. B. Zoneff has represented the expansion of the Bulgarian people in the river-basins of the Bulgarian Morawa and the Timok relying chiefly on linguistic argumentation; he added to the map an explanatory note determining the boundary between Servians and Bulgarians by the spoken tongue. The map has been published in "Petermanns geographischen Mlttellungen" 1915, table 44.

We cannot sufficiently regret that want of space in the atlas necessitates such a diminution of the map as will make its use without a magnifying glass scarcely possible; but as for the maps by Hahn and Kantschoff, we kope that the reader will take the trouble to find himself aright on this map too. These three maps are worth this trouble.
