The means which his excellency placed at my disposal were well
calculated to attain the object in view, and it is a matter of the most
sincere regret, that the nature and description of the country which we
passed through was for the most part such as to afford few interesting
objects of research or remark.

The botanical productions of the country have however in a great measure
been ascertained by Mr. Allan Cunningham, the King's botanist, who
accompanied the expedition.

With respect to the construction of the chart prefixed to this Journal,
it is thought proper to observe, that the situation of the principal
stations of Bathurst, and the depot on the Lachlan River, were
ascertained by celestial observations, and connected by a series of
triangles, commencing at the latter point, and closing at Bathurst. New
base lines were frequently measured, and any unavoidable errors which
might arise from the nature of the country were corrected at every proper
opportunity by observed latitudes; so that on the return of the
expedition to Bathurst, I had the satisfaction to find the connection of
the angles complete, the error in the whole survey not exceeding a mile

The instruments chiefly used were a small theodolite by Ramsden, and

the advantages of the circumferentor, without being so liable to be
damaged and put out of order by carriage.], with the addition of an
excellent sextant, pocket chronometer, and artificial horizon. I have
to lament that our mountain barometers were broken at an early stage
of the expedition; the height however of some principal points had been
