t; and, as our latitude is the same as the Reedy Brook of
Leichhardt on the south-west side of the Valley of Lagoons, it is evident
that these streams do not join the Burdekin, but are tributary to the
Lynd, joining it probably at the southern bend.

Latitude by b Aurigae 18 degrees 38 minutes 12 seconds.

At 6.25 a.m. steered east and traversed a slightly undulating granite
country, with small watercourses trending west-south-west. Ironbark and
box formed an open forest, the soil poor and gritty, with a few patches
of black soil, with blocks of lava on the surface. At 11.15 ascended a
small hill of lava, from which the country appeared very level to the
east. To the north-east large hills rose about twelve miles distant;
ranges also bounded the plain to the south, and some distant summits were
visible to the south-east. Continuing an east course, lava became more
frequent, and at length covered the whole surface. At 2.30 p.m. came on
several streams of lava, forming ridges of rugged rocks, which were
crossed with difficulty. These streams of lava appeared to have run from
north to south, the thickness twenty to thirty feet, and breadth very
variable. The level ground was lightly timbered with ironbark and box. At
5.25 turned to the south-east, following a small gully. Passed a small
native well; but very little water in it, and the rock prevented it being
enlarged. At 6.15 camped near some large rocks, in which five or six
gallons of rainwater had collected. Walking down the creek one and a half
miles in search of water, found two small pools of rainwater; but the
darkness of the night and broken nature of the ground prevented the party
moving to them.

14th October.

Moved the camp to the waterholes found last night, one and a half miles
down the gully. The country is here granite formation, undulating and
moderately grassed, and wooded with box and ironbark. The day was cloudy,
but cleared at night, and I took sights for time, latitude, and lunar
distance. Chronometer 2287 would not wind up in the morning, and stopped
during the day, but, having run down, wound again without difficulty.

Longitude by lunar distances 144 degrees 33 minutes 15 seconds; latitude
by e Pegasi 18 degrees 41 minutes 38 seconds; variation of compass 5
degrees 50 minutes east.

Resumed our journey at 7.0 a.m., and followed the course of the creek to
the south-east. The north-east side was a plain of lava
