extend along this part of the coast. To the east the level sandy plain
extended from eight to ten miles, and then rose into high sandstone
hills, covered with scrub and destitute of trees; but at the junction of
the limestone and sandstone formation, along which lay our route, were
several small lagoons and swamps of fresh water, with grassy margins. At
10.0 altered the course to southward; the line of swamps trending to
south-south-west, we entered the level sandy plain. At noon passed a
shallow pool of rainwater in a slight depression of the plain, and
shortly after crossed two small watercourses trending west; a little
brackish water remained in the deeper portions of their channels. The
effect of refraction on this level country, when heated by the midday
sun, was so great as to cause many of the low sandy ridges to appear like
large lakes and inlets of the sea, as in some instances the more distant
hills were obscured by its effects. At 2.45 p.m. we reached the sandstone
range, and at 3.5 halted in a small patch of grass around a native well
of good water, which had the appearance of retaining water throughout the
summer. While here we obtained several additions to our small collection
of birds.

MOUNTS PERON AND LESUEUR.

7th November.

At 7.20 a.m. resumed our journey southwards, over a high and somewhat
rugged range of sandstone hills; passed a short distance to the east of
Mounts Peron and Lesueur. The valleys were wooded with red and white-gum
of large growth, but the hills produced little besides coarse scrub. At
2.20 p.m. passed a large mound spring; at 2.45 crossed the Hill River of
Captain Grey; the land on its banks, with the exception of a few grassy
hills on the northern side, was very scrubby and indifferent. Ascending
