No change occurred in the country the next day, but the march was saved from its usual monotony by Warri finding two mallee-hens’ nests.  Unluckily they had no eggs, though the birds’ tracks were fresh and numerous.  These nests are hollowed out in the sand, to a depth of perhaps two and a half feet, conical shaped, with a mouth some three feet in diameter; the sand from the centre is scraped up into a ring round the mouth.  Several birds help in this operation, and when finished lay their eggs on a layer of leaves at the bottom; they then fill in the hole to the surface with small twigs and more leaves.  Presumably the eggs are hatched by spontaneous heat, the green twigs and leaves producing a slightly moist warmth, similar to that of the bird’s feathers.  I have seen numbers of these nests, never with eggs in, but often with the shells from recently hatched birds lying about.  How the little ones force their way through the sticks I do not understand, but Warri and many others who have found the eggs assure me that they do so.

Towards evening we neared a prominent bluff that we had sighted the day before, and got a further insight into the habits of the wild dog.  A dingo—­a female, and possibly our friend with the pups—­had followed us persistently all day.  Godfrey, who was walking behind the camels, opened the acquaintance by practising his revolver-shooting upon her.  His poor aim seemed to give her confidence, and before long she started to play with Val.  By nightfall we had petted and fed her out of our hands, and given her a small drop of water from our fast diminishing supply—­this at the earnest request of Godfrey, who offered to give her some of his share; and indeed it seemed rather cruel to refuse a poor famished beast that had come to us in her distress.  We all agreed how nice it was to have won the affections of a real wild dog.  By daybreak our feelings of love had somewhat abated, as our friend prowled about all night, poking her nose into pots and pans, chewing saddles, pack-bags, straps, and even our blankets as we lay in them, and cared no more for blows than for the violent oaths that were wasted upon her.  This strange creature accompanied us for two more days, trotting along ahead of the camels, with an occasional look behind to see if she was on the right course, and then falling at full length in the shade of some bush with her head on her paws, waiting for us to pass.  Eventually my irritability got the better of my indulgence, and a shrewd whack over the nose put an end to our acquaintanceship.

Near the bluff were many low, stony hills, with the usual small watercourses; in them we hunted high and low for water until darkness overtook us.  To the North other similar hills could be seen, by my reckoning a part of the Ernest Giles Range (Wells, 1892).  No doubt from the distance these hills would look more imposing.  Our camp was in lat. 27 degrees 9 minutes, long. 123 degrees 59 minutes.  August 6th.
