He stared at them for some time, as if he thought he must be dreaming, then, signing to the others, they all dropped on their haunches, and shuffled off in the quietest manner. Near their fire was a worley (native hut) large enough to shelter a dozen blacks; it was on the northern outskirt of the forest, and looked out across a marsh which is sometimes flooded by sea-water. Upon this were hundreds of wild geese, plover, and pelicans. After they crossed it they reached a channel through which the sea-water enters, and there passed three blacks, who silently and unasked pointed out the best way to go. Next day, Billy being completely tired, they short-hobbled and left him, going forward again at daybreak in the hope of at last reaching the open sea. After following the Flinders (this country had already been explored by Gregory) for about fifteen miles, and finding that the tide ebbed and flowed regularly, and that the water was quite salt, they decided to go back, having successfully accomplished one great object of their mission, by crossing the Australian continent from south to north. After rejoining Gray and King on February 13, the whole party began the return march. The incessant and heavy rains that had set in rendered travelling very difficult; but the provisions were running short, and it was necessary to try to get back to the depot without delay. The damp and suffocating heat that brooded in the air overpowered both man and beast, who were weak and weary from want of rest; and to breast the heavy rains and to swim the rapid creeks in flood well-nigh exhausted all their strength. Day after day they stumbled listlessly onward; while the poor camels, sweating, bleeding, and groaning from fear, had their feet at almost every step entangled by the climbing plants that clung to the rank grasses, which had rushed in magical growth to a height of eight or ten feet. If for a moment they went to windward of their camp fires they were maddened by swarms of mosquitoes, and everywhere were pestered by ants. Wonderful green and scarlet ants dropped upon them from the trees as they passed; from every log or stick gathered for the fires a new species crept; inch-long black or brown 'bulldogs' showed fight at them underfoot: midgets lurked in the cups of flowers; while the giant white ant ate its stealthy way in swarms through the sap of the forest trees from root to crown. Every night fierce storms of thunder crashed and crackled overhead, and the vivid lightning flaring across the heavens overpowered the moonlight. Gray, who had been ailing for some time, grew worse, though probably, as they were all in such evil plight, they did not think him really ill. One night Wills, returning to a camp to bring back some things that had been left, found him hiding behind a tree eating skilligolee. He explained he was suffering from dysentery, and had taken the flour without leave.
