eamp. Mr. Heidenreich sent a blackfellow with the party to 
show me a large waterhole in Ellery’s Creek. six and a half 
miles east of the station. An hour was spent here in making 
additions to Professor Spencer’s collection. I then continued east- 
ward for an additional fourteen miles, and camped at sundown in 
a dense mulga scrub. The country travelled over to-day turned 
out to be inferior to the other portions of the Missionaries Plain 
traversed by us, consisting of low sandhills and sandy flats covered 
with porcupine and patches of coarse grass, and timbered with 
drooping acacia, mulga, stunted mallee, and low cassia bushes. I 
have named a prominent round hill in the James Range, bearing 
184° from this camp and eleven miles distant, Mount Keartland, 
after Mr. G. A. Keartland, the indefatigable ornithologist of the 
expedition. ‘the western point of the Waterhouse Range bears due 
east and is four and a half miles away. 
Tuesday, July 10th.—Camp No. 45, bar. 27°6lin., ther. 37° ; 
height 2,009ft. The thermometer descended to 15° below freezing 
point last night. To complete the work allotted to the expedition 
it is necessary to visit Paisley’s Bluff in the Macdonnell Ranges. 
I have therefore decided to send the main party with Dr. Stirling 
and Mr. Keartland on from here by the road to Owen Springs 
Station, and thence to Alice Springs. I myself, in executing Mr. 
Horn’s final instructions, proceeded with Professors Tate and 
Spencer, Mr. Belt, two men, and six camels to the ranges. Started 
on a bearing of 44° 50’ in the direction of a high bluff east of 
Mount Conway. Our course was over sandy soil, covered with 
porcupine and densely timbered with mulga, drooping acacia, and 
mallee scrub. At two miles the country became undulating, and 
was covered with small stony pebbles, the scrub being denser than 
ever. We crossed the sources of numerous small creeks, all 
trending to the S.E. At eleven miles we got among some low but 
very rough and precipitous stony rises, terribly overgrown with 
porcupine grass. Sundown found us camped on a small teatree 
creek, near the base of the southern ridge of the Macdonnell 
Ranges, a stage of seventeen and a half miles having been made. 
{ followed this creek into the range, and discovered a small spring 
about a quarter of a mile to the north of our camp. I have named 
the spring Edgar’s Spring, after H. Edgar, a member of the 
expedition. Its water, which flows for about 30yds. and then disap- 
pears, emerges from a crevice in the conglomerate rocks; the latter 
extend from here to the Finke Gorge and to near Mereenie Bluff. 
To-day’s journey has been most distressing to the camels and 
horses—the latter have now been for two days without a drink; 
for them, therefore, the finding of water has been a most opportune
