Probably this may be taken as an indication that the lake is actually shrinking. Between these two ramparts, which run faithfully parallel to the outline of the lake, there are a number of lagoons, some containing water, others dry, and all with fine sediment in their bottom. All the brooks that find their way into the lake empty themselves first into similar lagoons, and the lagoons, which are always completely separate
from the lake, are connected with it by underground emissaries. The water in the lagoons is perfectly fresh.

Finally the lake narrows to a point in the west. There it is entered by a brook, which at that time carried a volume of only I cub.m. It comes from that particular latitudinal valley which forms the west-north-westward continuation of the lake, or rather, to speak more correctly, the valley which drains eastward down to lake No. XX. This latitudinal valley is bounded on the north first by the Arkatagh, possessing there a couple of dominating peaks, and secondly by the recently mentioned chain that terminates at the lake. The spurs of the Arka-tagh here jut
