COASTS OF AUSTRALIA.

After another unsuccessful search in the bight, i 82 i. 
to the eastward of Careening Bay, in which we July 24. 
fruitlessly examined a gully that Mr. Cunning- 
ham informed me had last year produced a con- 
siderable stream, we gave up all hopes of success 
here, and directed our attention to the cascade 
of Prince Regent’s River ; which we entered the 
next afternoon, with the wind and tide in our 
favour, and at sunset reached an anchorage at 
the bottom of St. George’s Basin, a mile and a 
half to the northward of the islet that lies off 
the inner entrance of the river, in seven fathoms 
muddy sand. 
The following morning, at half-past four o’clock, se. 
Mr. Montgomery accompanied me in the whale- 
boat to visit the cascade ; we reached it at nine 
o’clock, and found the water, to our inexpressible 
satisfaction, falling abundantly. 
While the boat’s crew rested and filled their 
baricas, I ascended the rocks over which the 
water was falling, and was surprised to find its 
height had been so underrated when we passed 
by it last year: it was then thought to be about 
forty feet, but I now found it could not be less 
than one hundred and fifty. The rock, a fine- 
grained siliceous sand-stone, is disposed in hori- 
zontal strata, from six to twelve feet thick, each 
of which projects about three feet from that
