-ource to its termination, and was enabled to ascertain that its general 
character was similar throughout. From the summit of the crater, the 
emanation of vapour water could be seen over a large area of country 
:o the north. 
On the mainland of New Guinea on the north-east coast, several 
large extinct craters were noticed, the most conspicuous being that of 
Mount Dayman, which reared its summit to over 9,000 feet above the 
llevel of the sea. I had an opportunity of obtaining an excellent view 
«of this huge volcano, when on an expedition, endeavouring to reach 
tthe summit of Mount Suckling, whose highest point reached over 
it, 000 feet above the beach at Collingwood Bay. Our progress to the 
summit was effectually barred at about 8,000 feet by an inaccessible 
precipice of quartz schist, which we aptly named Disappointment 
Rock. From this coign of vantage, it could be clearly seen that 
Mount Dayman, which was separated from us by a low divide, was the 
remains of a huge volcanic cone. This cone had been breached by a 
lava, which had flowed downwards to the north-east coast, and the 
lower portions of which we had traversed at considerably lower alti- 
tudes. Part of the crater wall is still extant, and from Disappoint- 
ment Rock, I could look right into the crater. Some of the Cloudy 
Bay lavas on the south coast in all probability emanated from the 
Mount Dayman volcano. The active volcano of Mount 
Victoria, which could be seen from Disappointment Rock, 
bore 352 degrees 30 minutes. In the year 1890 the Admin- 
istrator, in his inspection of the north-east coast of the 
Possession, viewed this mountain from Keppel Point, and gave an in- 
teresting description of it in the following terms : — “ This mountain is 
very steep and rugged, presenting towards the top great masses of bare 
rock. Its altitude is probably from 3,500 to 4,000 feet. Its sides 
were scored and marked by brown lines from near the summit to its 
base ; these at first looked as if caused by lava running down the 
mountain, but the closest inspection could detect no presence of lava, 
so that it was concluded that the lines had been caused by recent great 
earth slips. Some of the fishermen occupied near the Sydney Islands 
spoke of a smart shock of earthquake that had been felt about three 
weeks before in Collingwood Bay, so well marked that one man was 
thrown off a camp stool on the ground. A shock was felt on the 
mainland about the same time as far as Port Moresby. . . . The 
summit of the mountain was not visible from near Keppel Point on 
account of a dense cloud which rested upon it, when .he tops of 
Mount Suckling (11,000 feet) and Mount Trafalgar (4,000 feet) were 
quite unclouded. A column of steam could, however, be seen rising 
out of a ridge not far from the top of Mount Victoria, and in a few 
days later we had an opportunity in the early morning of seeing 
numerous columns of steam rising, some from the very tops of the two
