direction as the river. It continued in this manner for near four miles
more, when, without any previous change in the breadth, depth, and
rapidity of the stream, and when I was sanguine in my expectations of
soon entering the long-sought-for lake, it all at once eluded our farther
pursuit, by spreading at all points from north-west to north-east over
the plain of reeds which surrounded us; the river decreasing in depth
from upwards of twenty feet to less than five feet, and flowing over a
bottom of tenacious blue mud; and the current still running with nearly
the same rapidity, as when the water was confined within the banks of the
river. This point of junction with interior waters, or where the Macquarie
ceased to have the form of a river, is in lat. 30. 45. S., and
long. 147. 10. E.

To assert positively that we were on the margin of the lake, or sea, into
which this great body of water is discharged, might reasonably be deemed
a conclusion that has nothing but conjecture for its basis; but if an
opinion may he hazarded from actual appearances, which our subsequent
route tended more strongly to confirm, I feel confident we were in the
immediate vicinity of an inland sea, most probably a shoal one, and
gradually decreasing, or being filled up by the immense depositions from
the waters flowing into it from the higher lands, which, on this singular
continent, seem not to extend beyond a few hundred miles from the
seacoast; as westward of these bounding ranges, (which from the
observations I have been enabled to make, appear to me to run parallel to
the direction of the coast), there is not a single hill or other eminence
discoverable on this apparently boundless space, those isolated points
excepted, on which we remained until the 28th of July; the rocks, and
stones composing which, are a distinct species from those found on the
above ranges.
