ROCKS OF BULLABALAKIT.

The hill immediately over our camp was Bullabalakit, and consisted partly
of granular felspar, probably tinged greenish with chlorite; and partly
of concretionary porphyry, the concretions being mottled red and white,
and containing grains of quartz and crystals of common felspar; the white
concretions resisting the action of the atmosphere stood in relief on the
weather surface; I noticed also a vein of amethystine quartz.

December 24 and 25.

Ribs and thwarts were necessary to distend the canvas boats, and though
we had brought only moulds of each sort, yet we had tools and hands to
make them when required. We also sawed the pine wood into thin planks to
form a floor in each boat, whereon to lay our stores. We made the ribs of
bluegum (eucalyptus). The weather was excessively hot, yet the men worked
hard at the saw-pit notwithstanding; but all our activity was in danger
of being fruitless, for the river each day fell about four inches!

BOAT LAUNCHED.

December 26.

At half-past one P.M. the first boat was launched on the Namoi, and the
keel of the second immediately laid down. The delay occasioned by the
preparation of these boats was more irksome as the waters of the river
continued to subside.
