I, with Poole and a black, went out north to see what the country was like. On bearing 360 degrees over sandhills arrived at and found lake dry; four and a half miles of stones around it, same as in stony desert; went through the middle of it, it sweeps round from north-east to south-west; passed through it where it was two miles broad, it is fed from Lake Goonalcarae (now dry); the lake passed through has not had a supply of water for years apparently; lots of dead mussels and crayfish in its bed. At two and a half miles further (nine miles in all) over sandhills, changed course to 16 degrees for a large sandhill in the distance, the country to the north being rather low. At two and a half miles on this course came upon a succession of flooded basins, some of great extent, Gnatowullie, and slightly lined with stunted box, some as high up the sides of the sandhills as forty-five to fifty feet, entirely supplied by the rains but have not had a supply for some time, as there was neither water nor vegetation; which flooded basins continued till I went nine miles on this last course and from the top of the hill could distinctly see the beds of innumerable others of the same kind. From west round to north-east and east some dark-peaked sandhills, north-east of last course, as far as I could discern with the aid of a glass; turned back on course of 200 degrees to where I saw some shady box trees about two and a half miles, and turned out horses to rest and went to camp direct. On bearing of 187 degrees at five and a half miles came to the watercourse that supplies the dry lake Marroboothana from Goonalcarae, which I have named the Ellar, and the creek that fills it, in which there is at present water, Ellar's Creek. Monday, January 6. Marked tree MK (conjoined), from 3 to 6-62, Dig arrow at 7 o'clock, and deposited a document in tin envelope for the search parties from the north coast. Started at 6.30 with the bullock-cart, the horses and camels following, for Lakes Lady Blanche and Sir Richard, for the purpose of following the creek I observed when there the other day, and which the natives inform me goes northward, then westward and southward, through the stony desert. Arrived about 3.30 by rather a circuitous route to the northward of our proper course, but was guided that way to avoid many heavy sandhills. Distance between twenty-two and twenty-three miles. Tuesday, January 7.
