From Blackall the party struck across the settled pastoral districts until they arrived at Cork station, on the Diamantina. From there they kept a north-westerly route through the then unexplored country lying between the Burke and Herbert Rivers. From the Herbert the Ranken was followed up for some distance, and the route was then to Buchanan's Creek, and down that creek to the last permanent water. From here the party struck north, and some permanent waters were discovered, amongst them being the Corella Lagoon, the finest lagoon in that district. Two lakes of large extent were also seen and named, but, although at the time of the explorer's visit they were extensive sheets of water, seven or eight miles in circumference, they were so shallow for a mile from their shores, that at that distance, they were only knee deep. A singular feature of the lakes of this depressed region, was the fringe of dead trees that surrounded them. From the age of the trees, and even borders of all the lake beds seen, both dry and full, it was evident that this must have been the result of an excessive flood, which had inundated this district during some past year. From the Corella Lagoon, where some two or three hundred natives were assembled to celebrate the peculiar tribal rites common to that religion, and which have never been witnessed by whites, the expedition proceeded north, and discovered a large creek running from east to west, which received the name of Cresswell Creek. This creek, which ran through fine, open downs, was followed until its course was lost in the flooded country, which is the end of most inland creeks. The last permanent water on it was named the Adder Waterholes, on account of the number of death-adders killed there. The first excursion from there towards the telegraph line, some ninety miles away, resulted, in such days of heat, in conjunction with cracked and fissured plains, that three horses died before returning to camp. The country was soft, and full of holes and hollows, and it being the height of summer, the horses could not travel long stages without water; so there was nothing to do but await at the Adder Waterholes the falling of a kindly thunderstorm, to assist them to bridge the gap that lay between them and the telegraph line. During their detention at this camp many excursions were made, and the country traversed found to be mostly richly grassed downs; and where flooded country was crossed numbers of the dry beds of former lakes, surrounded by the customary belt of dead forest were noticed. The long delay exhausted the supply of rations, but by means of game, horse-flesh, and the usual bush vegetable, "bluebush and pig-weed," the party fared sufficiently well.
