cxcviii INTRODUCTION. [Prior Discoveries. 
Flinders, we reached the top of a stony mount, from whence the highest 
peak was four miles distant to the north-west. Three or four 
leagues beyond it was a ridge of mountain, from which various 
small streams descend into Pumice-stone River ; the principal place 
of their junction seeming to be at a considerable extent of water 
which bore N. 8o° E., and was about six miles above the sloop. 
Early on the 27th, we reached the foot of the nearest Glass House, 
a flat-topped peak, one mile and a half north of the stony mount. It 
was impossible to ascend this almost perpendicular rock ; and find- 
no marks of volcanic eruption, we returned to the boat, and to the 
sloop the same evening. 
July 28, we proceeded down the river; but owing to strong 
winds and squalls from the south-east, did not clear it before the 
31st. Some communications with the natives had been obtained 
whilst the sloop was lying on shore ; and this detention afforded 
opportunities of repeating them. I am happy to say they were all 
friendly, which is attributable to their opinion of us having under- 
gone a salutary change from the effect of our fire arms at Point 
Skirmish. 
These people were evidently of the same race as those at Port 
Jackson, though speaking a language which Bongaree could not 
understand. They fish almost wholly with cast and setting nets, live 
more in society than the natives to the southward, and are much 
better lodged. Their spears are of solid wood, and used without 
the throwing stick. Two or three bark canoes were seen ; but from 
the number of black swans in the river, of which eighteen were 
caught in our little boat, it should seem that these people are not 
dextrous in the management either of the canoe or spear. 
The entrance of Glass-house Bay, from Point Skirmish to the 
inner part of Cape Moreton, is eight miles wide ; but it contains so 
many shoals that a ship would have much difficulty in finding a 
passage. These shoals are of sand, and in the channels between 
them are various depths from 5 to 13 fathoms upon similar ground ;
