Camp 16. Dewless night, wind from east by north. I take this to be the main branch of the Flinders; the hills on its right proper banks are very bold and must be over 3000 feet high. If they are not before named I have called them Gregory's Ranges after Augustus Gregory, Esquire, now Surveyor-General of Queensland. The point I changed my course at yesterday I have called Mount Wildash after F. Wildash, Esquire, of Queensland. Immediately east of Mount Wildash close by is another bluff equally high which I have called Hawker's Bluff after the Honourable G.C. Hawker. Started at 7.58 a.m. on bearing of 100 degrees for the southern end of dark range in the distance; at 8.30 south of conspicuous sandstone rocky peak which I have called Morphett's Peak after John Morphett, Esquire, of Adelaide; dip of about 35 degrees in the sandstone to about north-east or a little more east. Kept the above course three miles over good travelling country; spelled a few minutes then up and down and over very rocky ranges, in many places precipitous and most intricate travelling from 9 a.m. till 11.30; three and a half miles farther, then table-land till 1.50, the drainage is to the east, no doubt to go south after it has cleared the rocky ranges; spelled, watering the camels from 2.25 to 2.45 p.m., up to this eight and three-quarter miles further. Commenced ascending another mass of similar rocky ranges; stopped at 3.40 two and a quarter miles further to look out a track to endeavour to get out of this awful place. Started again at 4.55 p.m. after spelling one and a quarter hours, could not get the animals over. Went back till 5.22 one mile on our track, or to sixteen and a half miles on bearing 100 degrees, to try another place, southerly and westerly along and over very rocky ranges till 6.15, about two miles on average bearing of 215 to 220 degrees. Came to a small sandy creek, then another, where by digging we will be able to give the animals some water, there is plenty of feed; it has been a very distressing day for the poor brutes; distance sixteen and a half miles on course of 100 degrees, and two miles on 220 degrees; gave each of the animals from two to five buckets. Although when first seen the little water that was visible did not exceed a quart with a few small dead fish about 1 1/2 inches long, but after digging and clearing away the sand we got sufficient for tonight and tomorrow morning. It has been close and oppressive which has added to the distress of the horses and camels. One of the latter, an old Indian, could hardly be persuaded to come along. Very light rain commenced about dark or a little after, but I doubt whether it will come to anything; however it will damp the grass for the poor animals and make it more palatable. Saturday, June 14.
