upon a convenient station on the north point of the bay
within Lammas Island, a small rocky islet covered with shrubs, and
separated from the easternmost point of Greville Island by a very shoal
and rocky channel.

During these occupations we examined Munster Water: on our way to it we
landed on the reef off the east end of the Midway Isles, which was found
to be more extensive than had been suspected, and to embrace the group of
small rocks, which at high-water only just show their summits above the
water; at high-tide there is at least fifteen feet water over it, but
being low-water when we landed, the reef was dry. Upon it we found
several varieties of coral, particularly Explanaria mesenterina, Lam.;
Caryophylla fastigata, Lam.; and Porites subdigitata, Lam.: the only
shell that we observed upon the reef was a Delphinula laciniata, Lam.
(Turbo delphinus, Linn.). After obtaining bearings from its extremity, as
also from the summit of the outer dry rock, we landed upon a small
verdant-looking grassy mound, the northernmost islet of the group; but we
found the verdure of its appearance was caused only by the abundance of
the spinifex, through which we had, as usual, much difficulty in
travelling. After procuring some bearings from its summit we re-embarked
and pulled up Munster Water, supposing that it was connected with the
strait at the back of Greville Island; but as the tide then flowing was
running in a contrary direction to what was expected from the hypothesis
we had formed, we began to suspect some other communication with the sea,
and in this we were not deceived; for a narrow but a very deep strait
opened suddenly to our view, at the bottom of the Water, through which
some of the islands in the offing were recognised. In pulling through we
had kept close to the south shore, that we might not miss the
communication with Hanover Bay, but notwithstanding all our care we
passed by without noticing it, on account of the deceptious appearance of
the land; indeed the strait which we discovered leading to sea was not
seen until we were within two hundred yards of it, and would also have
escaped our observation had not the channel been so direct that the sea
horizon was exposed to our view. At the bottom of this arm are two deep
bays which were partially but sufficiently examined. In most parts of
Munster Water there is good anchorage amongst several small rocky
islands, on one of which we landed, and climbed its summi
