Since the date of Captain Stokes's survey, Captain Grey has himself virtually admitted Champion Bay to be the locality visited by him. In a letter to that officer dated, "Government House, Adelaide, January 28, 1842," and published in the South Australian journals, Captain Grey observes, "I have attentively read your letter to the Hon. the Surveyor-General of Western Australia; and have also considered the observations made by you to me, relative to the error you suppose I have fallen into in mistaking the Wizard Peak of Captain King for the hill named by him Mount Fairfax, and I find I have certainly fallen into this error -- a by no means unlikely one, considering the very similar character of the singular group of hills called Moresby's Flat-topped Range, and the circumstances under which I was journeying." 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.
