ample sandy beach, while others are fringed with belts of 
mangrove bushes. In some of the islands, between the ranges 
of hills, there are wide plains but thinly wooded with Hucalypti, 
and, after the rainy season, covered with high grass. Springs of 
water are to be found on nearly all the islands throughout the 
year, and after the rains there is generally a profusion in the 
eullies and water-holes. Thursday Island, being so small, is but 
poorly provided, and the inhabitants store up rain-water in tanks 
to meet their necessities during the dry season, the water in the 
water-holes being unfit for human consumption. 
Thursday Island is one mile and a half long by about three- 
quarters of a mile wide, and has a range of hills running half-way 
through it in a north-easterly direction, divided by a moderately 
broad valley crossing the island from north to south, and beyond 
this again there is a range of hills in the north-east corner of the 
island, and another range in the south-east corner. The highest 
point is 374 feet high. ‘The settlement is situated upon Vivien 
Point, the south-west extremity of the island, and extends along 
the beach for about half a mile from thence. The whole island 
is surrounded by a coral fringe reef. 
After lunch I went on shore with three of my messmates, 
Lieutenants Ommanney and Allenby, and Mr. Hunter, midship- 
man. ‘The two former I provided with nets and boxes, as they 
were anxious to help me, as they said, to complete my collection 
of the Australian butterflies, as this would be the last opportunity 
we should have of landing in Australia. We landed on the beach 
a little to the north-east of the settlement, and walked to the 
valley which intersects the island, and across this to a range of 
hills which he in the north-east corner, and whose highest point, 
Rose Hill, is 223 feet. The valley was sparsely clothed with 
trees, the chief of them being Hucalypti, Casuarina, Banksia, 
Persoonia, &c. Grass was abundant everywhere, and in some 
places, especially at the edge of the forest, was breast high. 
There were also a few small Acacia and Cassia bushes, and some 
others I am unacquainted with; and here and there patches of 
vetches and other leguminose plants. The ground in many 
places was thickly strewn with volcanic blocks of stone, and 
these, hidden among the grass, made walking dangerous and 
unpleasant, and running almost out of the question. Most 
conspicuous objects in this valley were the cone-shaped or
