rain water hole in the Darwent. Leaving the creek to the west we 
continued on a bearing of 318° in the direction of the eastern point 
of the eastern bluff. At half a mile we crossed a large gum creek 
which joins the Darwent half a mile to the N.W. After this a 
few outcropping rocks indicated a geological change, micaceous 
schists, epidote, and other granitoid rocks appearing. At two 
miles and four and a quarter miles we crossed some small quartz 
reefs. Then the course was changed to 323° 35’, still through 
richly-grassed mulga scrub, with saltbush and cotton-bush flats. 
At four and a quarter miles we reached the foot of some hills to 
the east of the high bluff, and camped. Professor Tate employed 
the rest of the day in examining the geological structure of this 
peculiar range, which here consists of three distinct and lofty 
mountains, the western one being the loftiest of them, and the 
second highest mountain, not only in the Macdonnell Ranges, but 
in the whole of South Australia. The eastern bluff has an immense 
capping of quartzite, which rests on metamorphic rocks. This 
quartzite presents a perpendicular face or escarpment to the 
southward, and is 3857ft. in height. ‘lhe altitude of the bluff itself 
is 1,535ft. above the surrounding plain, and 3,690ft. above sea 
level. The height of the middle gigantic hill is 4,009ft., whilst 
the western, and at the same time most massive of the rises, has 
an elevation of 4,646ft. The natives seem to have no particular 
name for these imposing geographical features Throughout the 
journey I have endeavored to obtain the aboriginal appellations 
for all objects seen, but in this instance the words given by 
different natives are totally at variance, and seem to be descriptive 
for the occasion only. I have therefore styled these three im- 
portant mountains Mount Edward, Mount William, and Mount 
Francis. after the brothers, Messrs. Edward, William, and Francis 
Belt respectively, and the range to which they belong the Belt 
Range. Dr. Stirling and I, with the black boy Racehorse, pro- 
ceeded to the northern side of the range, passing the Welcome and 
other springs, in search of two corrobboree stones said to have 
been hidden here by the natives. Before we started I was not 
aware of the doctor’s object in wishing to visit this spot. I ac- 
companied him because | desired to sketch in the northern 
portions of the range and connect my present traverse with my 
previous work of 18738. Eventually, however, the information 
obtained by him from Mr. R. Coulthard, of ‘'empe Downs Station, 
relative to the stones was communicated to me. ‘The directions for 
finding them were most explicit, and we followed them out to the 
letter, but a three hours’ search among the innumerable outcrops 
of rocks proved unavailing, and we returned to the camp without
