The hill, therefore, at whose foot Captain Grey halted on the afternoon of April 7, 1839, was not Mount Fairfax, but the Wizard Peak, or some other hill "to the north of Mount Fairfax." From thence the "sandy downs," (mentioned in the extract from his Journal that I have given above) over which he passed in the evening continued to within "half a mile of the sea," where "they terminated in cliffs." To have seen all this he must have been walking at no very great distance from the shore during that day's marsh. His object was to reach Perth as quickly as possible; and he steered in the most direct course—"south by east." We know, therefore, exactly the line of country traversed by Captain Grey—the "singular group called Moresby's Flat-topped Range" being unmistakeable.
In December, 1844, H. M. colonial schooner, Champion, under the command of Lieutenant Helpman, R.N., accompanied by Mr. J. Harrison, Civil Engineer, etc., was again despatched by Governor Hutt to make further observations in the neighbourhood of Gantheaume Bay. Lieutenant Helpman says in his report, "I coasted close in from Champion Bay, collecting angles and soundings until in latitude 28 degrees 10' 30", S. the low ridges of sand along the shore induced me to land, being then (as I concluded from the latitude given by Captain Grey) in the immediate vicinity of the estuary." This estuary is described by Captain Grey in his diary of the FIFTH April, who states that "for one mile we continued along THE RICH FLATS which bordered the estuary" ... "we ascended the limestone range, and got a view of the country to the eastward and found it STILL GRASSY, and exactly the same character as far as we could see. For the next five miles we continued along the top of the limestone range, the estuary still occupying the valley which lay to the west of us." ... "At the end of a mile in a south by east direction, we found ourselves on the banks of a river, the Hutt, from forty to fifty yards wide, which was running strong, and was brackish at its mouth," etc. Such was the appearance of the estuary and of the Hutt River in the eyes of Captain Grey.
Lieutenant Helpman continues his report as follows:—
"On reaching the summit of the highest coast hill I found myself abreast of the centre of the inlet, which was void of water, but presented the appearance of a continuous sheet of salt as far as the eye could reach. Passing over the coast ridges, I came down, in about half a mile, to the edge of the estuary, and followed it in a southerly direction for about two miles, when I ascended another hill, from which I could clearly see the south end of it, which was covered with the same description of incrustration of salt.
"A gorge at the south-east corner of the estuary is probably where the Hutt River discharges itself during the rainy season, but there was no appearance of water in any part of the flat, which was about two miles wide between the hills and the south-east shore of the inlet.
"Observing that the north extremity of the estuary, as seen from the hill just referred to, presented some slight appearance of water, I was induced to examine it, and found the sand ridges on the coast extremely low, nearly destitute of herbage, but giving the idea of having had water passing over them. This I judged to be the case, from a few blades of very coarse grass which were laid flat on the ground, as if from the effects of running water.
"From the highest point of these ridges, notwithstanding the smoke from the numerous native fires, the whole north end of the inlet was plainly seen to be covered with salty incrustations, similar to those previously referred to.
"I conceive the point of land near which these latter observations were made, and where I landed the second time, to be Shoal Point of the chart; but, except that it is very low, I see no cause for its name, as the water was deep close to it, and having only a few rocks close off its extreme west point, within a quarter of a mile of the shore.
"Following close in from Shoal Point, the coast is perfectly clear of dangers; but I observed no opening in the hills indicative of a river, nor could I discover any bay or place of shelter for shipping to resort to.
"Red Point, which is the western entrance of Gantheaume Bay, is a very bold headland of considerable elevation, it is circular, and about four miles in extent. I landed at the east end of the red sand cliffs, taking a specimen of the rock.
