occurred. First we passed a stretch of clear, brackish water, then a
nearly dry reach of sand, then a trickle of fresh water lasting for a
hundred yards or so; this would again disappear, and be seen lower down
as another salt pool.

The creek enters the first lake in a broad estuary; this lake is some
four miles long by two miles wide, lying North and South. At the southern
end a narrow channel, 150 yards wide, winds its way into the large lake
beyond, a fine sheet of water, eight miles in diameter. A narrow belt of
open country, overgrown with succulent herbage, fringes the margin of the
lake; beyond it is dense scrub, with occasional patches of grass; beyond
that, sand, sandhills, and spinifex. In the distance can be seen
flat-topped hills and bluffs, and rising ground which encloses the hollow
of the lake. The lake has no outlet; of this Gregory satisfied himself by
making a complete circuit of it. At the time of his discovery the lakes
were dry, or nearly so, and doubtless had the appearance of being shallow
depressions, such as the salt lakes in the southern part of the Colony;
so that having followed the Sturt for so many miles--a creek which showed
every appearance of occasionally flooding to a width of five or six
miles--he must have been somewhat uncertain as to what happened to so
great a volume of water. However, the lake is nearly thirty feet deep in
the middle, and, from its area, is capable of holding a vast amount of
water. The creek, below its confluence with the Wolf, is continually
losing its waters, throwing off arms and billabongs, especially to the
west, which form swamps, clay-pans, and lagoons. So much water is wasted
in this manner that near the entrance into the lake the creek is of a
most insignificant size. The fall, too, is so gradual that the water runs
sluggishly and has time to soak away into the enclosing sand.

Mr. Stretch tells me that it takes eight days for the water from rain
