The primary object of the voyage having been attained, it was considered desirable to avail of the opportunity to examine the country to the northward and ascertain its capabilities for settlement; for though Captain, now Sir George Grey, had seen some good country on his journey along the coast from Gantheaume Bay to Swan River, in 1839, Captain Stokes, who landed from the Beagle subsequently and ascended Wizard Peak about twelve miles inland, had distinctly negatived the existence of any country capable of occupation, though, as an illustration of the difficulty of ascertaining the real capabilities of country by partial and hurried inspection, it may be observed that this has since become one of the most prosperous districts of Western Australia in regard to its pastoral, agricultural, and mining industries. For the purpose of making this examination of the country, Messrs. A.C. Gregory, H.C. Gregory, and Lieutenant Irby, taking three horses and three days' provisions, left Champion Bay on the 20th December, the following being a copy of the journal:-- 20th December, 1846. At 6.20 a.m. left the bivouac and followed the shore of Champion Bay about a mile northerly; then steered 87 degrees over a scrubby country; at 7.20 crossed the Chapman River; and at 8.0, being a quarter of a mile north from Mount Fairfax, altered the course to 66 degrees, the country being thinly covered with wattle scrub and some grass; at 8.45 crossed a large branch of the Chapman with several small pools of water in the bed; the country beyond was more scrubby and the soil gravelly; at 9.0 changed the course to 18 degrees, and at 9.20 again crossed the Chapman River just below a pool of apparently permanent water; at 9.50 crossed a granite ridge, beyond which the country improved, with many large patches of grass to the eastward; at 10.20 ascended a high flat-topped hill of red sandstone resting on granite, which proved to be the eastern point of Moresby's Flat-topped Range. From this hill Mount Fairfax and Wizard Hill were visible to the east; grassy hills rose gradually from the Chapman River for seven or eight miles; steering 10 degrees over grassy country, the soil was composed of detritus of granite and trap rocks; at 11.0 came on a large party of natives, some of whom accompanied us for about a mile, pointing out places where we should find water. At noon turned to the north-east and entered an extensive valley with some patches of grass, but not generally of a good character; at 12.30 p.m. crossed a small watercourse trending west; followed it about half a mile, and then steered north-west over scrubby flats till 1.0, when we struck a small stream-bed with small pools of water, and halted till 1.20, and then followed up the stream to the north till 3.0, when we bivouacked. 21st December.
