tioB-j comes as far soutli as 20° 20'^ tlie latitude of the upper end 
of the lakcj and^ instead of flooding the country, falls into the 
lake as into a reserToir. It begins to flow down the Embarrah, 
which divides into the rivers Tzo and Teoughe. The Tzo divides 
into the Tamuiiakde and Mababe; the Tamunak’le discharges 
itself into the Zouga, and the Teouglie into the lake. The flow 
begins either in March or April, and the descending waters find 
the channels of all these rivers dried out, except in certain pools in 
their beds, wMch have long dry spaces between them. The lake 
itself is very low. The Zouga is but a prolongation of the 
Tamunak’le, and an arm of the lake reaches up to the point 
where the one ends and the other begins. This last is narrow 
and shallow, while the Zouga is broad and deep. The narrow 
arm of the lake, which on the map looks like a continuation of 
the Zouga, has never been observed to flow either waj. It is as 
stagnant as the lake itself. 
The Teouglie and Tamunakde, being essentially the same river, 
and receiving their supplies from the same source (the Embarrah 
or Varra), can never outrun each other. If either could, or if 
the Teouglie could fill the lake—a tiling winch has never hap¬ 
pened in modern times—then tliis little arm would prove a con¬ 
venient escapement to prevent inundation. If the lake ever 
becomes lower than the bed of the Zouga, a little of the water of 
the Tamunak’le might flow into it instead of down the Zouga; 
we should then have the phenomenon of a river flovdng two ways; 
but tins has never been observed to take place here, and it is 
doubtful if it ever can occur in tins locality. The Zouga is broad 
and deep when it leaves the Tamunakle, but becomes gradually 
narrower as you descend about two hundred miles; there it flows 
into Kumadau, a small lake about three or four miles broad and 
twelve long. The water, which liigher up begins to flow in Aj}!*!!, 
does not make much progress in filling tliis lake till the end of 
June. In September the rivers cease to flow. When the supply 
has been more than usually abundant, a httle water flow^s beyond 
liumadau, in the bed first seen by us on the 4th of July; if the 
quantity were larger, it might go further in the dry rocky bed of 
the Zouga, since seen still further to the east. The water supply 
of this part of the river system, as will be more fiiUy explained 
further on, takes place in channels prepared for a much more
