TO KOLAINA AND BACK TO THE GASCOYNE.
EXAMINE THE COAST TO THE NORTH OF THE GASCOYNE.
March 7.
When we got outside the mouth of the Gascoyne a fresh breeze was blowing from the south-east.

We ran along the shore west by north, keeping about a quarter of a mile from it; and after having made about three miles and a half we reached the southern extremity of the other mouth of the river.
The mean depth in our course along Babbage Island had been from two and a half fathoms to three fathoms; and this opening had a bar which we then conceived to run right across the mouth of the river.

The northern extremity of Babbage Island is a very remarkable low point of land which I called Mangrove Point.

It cannot fail to be recognised for it is the first point from the northward along the eastern shores of Shark Bay where mangroves are found, and from that point they extend almost uninterruptedly down the eastern coast of this bay to the south, as far as I have seen it.
CONTINUE THE COURSE TO THE NORTHWARD.
The coast now trended north by west and we continued to run along it.
After passing Mangrove Point the sandy dunes along the shore ceased, and the land appeared to be scarcely elevated above the level of the sea: not a hill or tree could be perceived, and a low black line almost level with the water's edge was the only indication that we had of being near land.
LYELL'S RANGE.
This kind of shore continues for about nine miles, when low sandhills begin to rise parallel to the coast, and these gradually increase in altitude until they form that remarkable range of dunes which I have called Lyell's Range.
