The next day we landed on the west head of the bay, Crystal Head, where
the meridional altitude of the sun was observed and sights for the
chronometers taken; in the evening we ascended its summit and by a
bearing of the land of Cape Bougainville the survey was connected with
Vansittart Bay.

In the morning a young kangaroo was started by Mr. Cunningham but made
its escape; the traces of these animals were very numerous on the sides
of the hills; several birds new to us were seen, and we also found about
the bushes the tail-feathers of the Cuculus phasianus (Index Orn. Sup.
page 30). The summit of Crystal Head is of flat tabular form; and the
sides, which are both steep and rugged, are covered with stunted trees
and high grass, now quite dry: the geology of this part is principally of
siliceous sandstone; and on the beach we found large detached water-worn
masses of the same rock, incrusted with quartz and epidote in a
crystallized state.

No natives were seen; but, from the large fires that were burning, a
numerous party was probably collected at the bottom of the port.

October 11.

On the 11th we got under weigh and anchored again at a few miles further
up the port, near a small rocky island where the latitude was observed to
be 14 degrees 32 minutes 45 seconds. In the afternoon Mr. Roe and Mr.
