The southern portion is said to bend round to the west, and to receive the Teoughe from the north at its northwest extremity.

We could detect no horizon where we stood looking S.S.W., nor could we form any idea of the extent of the lake, except from the reports of the inhabitants of the district; and, as they professed to go round it in three days, allowing twenty-five miles a day would make it seventy-five, or less than seventy geographical miles in circumference.

Other guesses have been made since as to its circumference, ranging between seventy and one hundred miles.
It is shallow, for I subsequently saw a native punting his canoe over seven or eight miles of the northeast end; it can never, therefore, be of much value as a commercial highway.

In fact, during the months preceding the annual supply of water from the north, the lake is so shallow that it is with difficulty cattle can approach the water through the boggy, reedy banks.
