pertinacious.  I think the tropic fly of Australia the most abominable insect of its kind.  From the summit of the hill I ascended on Sunday, I found the line of mountains still ran on to the west, the furthest hills appeared fifty miles away.  As they extend so far, and are the principal features in sight, I shall follow them, in hopes of meeting some creek, or river, that may carry me on to the west.  It is a remarkable fact that such high hills as I have been following should send out no creek whose course extends farther than ten or twelve miles.  I could trace the creek I am now on by its timber for only a few miles, its course appearing south of west.  The country in its immediate neighbourhood is open, and timbered with fine casuarina trees; the grass is dry and long, and the triodia approaches to within a quarter of a mile of it.  The line of hills I previously mentioned as running along to the south of us, we had now run out.  I named them Gardiner’s Range, after a friend of Mr. Carmichael’s.  There is, however, one small isolated hill, the furthest outpost of that line, some three miles away to the south-west; the creek may probably take a bend down towards it.  I called it Mount Solitary.  This creek is rather well timbered, the gum-trees look fresh and young, and there is some green herbage in places, though the surface water has all disappeared.

There was so little water at the camp tank, we had to send the horses up the creek three miles to water, and on their return I was not sorry to be moving again, for our stay at these two last camps had been compulsory, and the anxiety, trouble, and annoyance we had, left no very agreeable reminiscences of the locality in our minds.

We travelled along the creek all day, cutting off the bends, but without seeing any signs of water:  towards evening we set to work to try if we could get any by digging.  In about four feet, water began to drain in, but, the sand being so loose, we had to remove an enormous quantity to enable a horse to drink.  Some of the horses would not go into it, and had to be watered with a canvas bucket.  The supply seemed good, but it only drained in from the sides.  Every time a horse drank we had to clear out the sand for the next; it therefore took until late before all were satisfied.  The country was still open, and timbered with fine black oak, or what is so called in Australia.  It is a species of casuarina, of the same family but distinct from the beautiful desert oak.  Triodia reigned supreme within half a mile.  At this camp the old grass had been burnt, and fresh young green shoots appeared in its place; this was very good for the horses.  A few drops of rain fell; distant rumblings of thunder and flashes of lightning now cooled the air.  While we were at breakfast the next morning, a thunderstorm came up to us from the west, then suddenly turned away, only just sprinkling us, though we could see the rain falling heavily a few yards to the south.  We
