anching westerly from Hardwicke's Range, bounds on that side this
extensive basin, which includes Liverpool Plains. Peel's River is the
principal stream, and receives, in its course, all the waters of these
plains below the junction of Connadilly,--which I take to be York's
River, of Oxley.

THE RIVER NAMMOY.

The stream is well known to the natives by the name Nammoy; and six
miles below Tangulda, the low extremities from the surrounding ranges
close on the river, and separate this extensive vale from the
unexplored country which extends beyond to an horizon which is unbroken
between W.N.W. and N.N.W.

The impracticable appearance of the mountains to the northward, induced
me to proceed thus far to the west; and on examining the country thirty
miles N.E. by N. from Tangulda, I ascended a lofty range extending
westward from the coast chain, and on which the perpendicular sides of
masses of trachyte (a volcanic rock) were opposed to my further
progress even with horses: it was therefore evident that the river
supposed to rise about the latitude of 28 degrees would not be
accessible, or at least available to the Colony, in that direction, and
that in the event of the discovery of a river beyond that range flowing
to the northern or north-western shores, it would become of importance
to ascertain whether it was joined by the Nammoy, the head of this
river being so accessible that I have brought my heavily laden drays to
where it is navigable for boats, my present encampment being on its
banks six miles below Tangulda. From this station I can perceive the
western termination of the Trachytic range, and I am now about to
explore the country between it and the Nammoy, and the further course
of this river; and in the event of its continuance in a favourable
direction, I shall fix my depot on its right bank, whence I now write,
and descend the stream in the portable boats.

I have the honour to be, Sir,
Your most obedient servant,
T. L. MITCHELL,
SURVEYOR-GENERAL

The Hon. The Colonial Secretary.

Peel's River, 29th February, 1832.

SIR,

I have the honour to inform you, for the information of His Excellency
the Governor, that I have reached the left bank of this River with my
whole party on my return from the northern interior, having explored
the course of the river referred to in my letter of 22nd December last,
and others within the 29th parallel of latitude.

There was so much falle
