On the Rostov and Wladikavkas railroad, in southern Russia, there rises out of the flat steppes, a few hours before reaching the last mentioned place, a remarkable group of steep-sided hills, or mountains, each isolated from the others. The principal town of the region is Piatigorsk, which is about ten miles from the railway station of Mineralniya Vody.
