THE CHARACTERISTICS OF THE CAUCASUS 41 Karagoiu Glacier, 5700 feet, reaches the lowest point on the northern side; on the southern side the Chalaat and Leksur Gh\eiers united at about five thousand feet not many years ago, and end now two to four hundred feet higher respectively. The point to which tlie glaciers descend would appear to be regulated much more by tlie size of their neves and the conformation of their beds than by their exposure : for instance, the Zanner and THE SOURCK OF THK INGfR Bezingi Glaciers, on opposite sides of the chain, both terminate between 6800 and 7000 feet. The suggestion that there are no more than 46 square miles of ice in the Caucasus may now be finally dismissed. It is too soon to say exactly what extent of ground in the whole chain is under ice. Let us avoid the snare of our predecessors, hasty generalisation, founded on imperfect material. Until the range as a whole has been scientifically mapped, no final and accurate estimate can be possible. But for the Central Caucasus alone,
