ran up to the foot of this line of ranges. The horses seemed to be especially pleased to be on soft ground again. The length of this glen is considerable, as it occupies 31 minutes of latitude. The main bearing of it is nearly north 25 degrees west; it is the longest feature of the kind I ever traversed, being over forty miles straight, and over a hundred miles of actual travelling, and it appeared the only pass through the range, which I named the Krichauff. To the north a higher and more imposing chain existed, apparently about twenty miles away. This northern chain must be the western portion of the McDonnell Range. The river now is broader than in the glen; its bed, however, is stony, and not boggy, the country level, sandy, and thinly timbered, mostly all the vegetation being burnt by grass fires set alight by the natives. Travelling now upon the right bank of this stream, we cut off most of the bends, which, however, were by no means so extensive or so serpentine as in the glen or on the south side of it. Keeping near the river bank, we met but little porcupine grass for the most part of the day's stage, but there was abundance of it further off. The river took us to the foot of the big mountains, and we camped about a mile below a gorge through which it issues. As we neared the new hills, we became aware that the late rains were raising the waters of the river. At six miles before camping we crossed a tributary joining the Finke at right angles from the west, where there are some ranges in that direction; a slight stream was running down the bed. My next anxiety is to discover where this river comes from, or whether its sources are to be found in this chain. The day was delightfully fine and cool, the breezes seemed to vibrate the echo of an air which Music, sleeping at her instrument, had ceased to play. The ground is soft after the late rains. I said we camped a mile below a gorge; at night I found my position to be in latitude 23 degrees 40', and longitude 132 degrees 31', the variation 3 degrees east. We shot a few ducks, which were very fat and good. This morning I took a walk into the hills to discover the best route to take next. The high ranges north seem to be formed of three separate lines, all running east and west; the most northerly being the highest, rising over 2000 feet above the level of the surrounding country, and, according to my barometrical and boiling-point measurements, I found that at the Charlotte Waters I was 900 feet above the sea. From that point up to the foot of these mountains the country had steadily risen, as we traced the Finke, over 1000 feet, so that the highest points of that range are over 4000 feet above sea level; the most southerly of the three lines is composed of sandstone, the middle and highest tiers I think change to granite. I climbed for several hours over masses of hills, but always found one just a little farther on to shut out the view. At length I reached the summit of a
