after having travelled another ten miles in various directions, we 
arrived at our destination, and ascertained from some aboriginals 
that our party had not yet turned up. Here we camped, having 
travelled thirty-nine miles. 
Monday, May 2Ist.—Camp No. 15; bar. 29°27in., ther. 31°. 
Decided to await the arrival of the main party here. At 9°30 a.m., 
while I was purchasing some food at the mail station, Mr. Horn 
and Harry arrived at the camp. I then learned that the main 
party had left the Goyder river on Wednesday shortly after my 
departure, camping that night and for the succeeding two days near 
Crown Point Station. The camel buggy was left here, and two 
camel pack saddles for the buggy camels were made by the 
Afghans. On Saturday the main party travelled from Crown Point 
towards tke junction of the Lilla and Finke rivers, camping on the 
Iilla, twelve miles from Crown Point and twenty-six miles from 
Ross Camp. Harry, the black boy, arrived at this camp towards 
evening of the day on which I dispatched him to Crown Point, and 
delivered my letters to Mr. Horn. In consequence of the receipt 
of these Mr. Horn on Sunday travelled the main party northward 
by the old track towards Engoordina Station, camping some two 
miles south of the mail station. With my companions I rejoined 
the main party in one and a half miles at the deserted cattle 
station, and the whole expedition then proceeded westward towards 
Idracowra, I mapping the-country on the way. At eighteen and a 
half miles we camped on Sullivan’s Creek. 
Tuesday, May 22nd.—Camp No. 16; bar. 29°03in., ther. 34°. 
Professor Spencer photographed the caravan this morning. The 
track now traverses the detached table-top range previously men- 
tioned. Numerous isolated hills are visible in every direction. 
Owing to this fact I was occupied all day in mapping. At nineteen 
miles we camped at Idracowra old station, on the Finke river. 
Several long reaches of. water were observed in the river about a 
mile south of our camp. ‘The caravan will remain here to-morrow 
for the purpose of enabling photographs of Chambers Pillar to be 
obtained. 
Wednesday, May 23rd.—Camp No. 17, Idracowra; bar. 29in., 
ther. 32°. I was occupied all day with the expedition plans and 
in working out the results of astronomical observations. Professor 
Spencer, Dr. Stirling, Mr. Watt, Mr. Belt, and Harry started for 
Chambers Pillar, which is about ten miles to the northward, in 
the morning, returning about 7 p.m. From rough measurements 
taken by Mr. Watt in following out my directions I computed the 
height of the pillar from its base to be 167ft. Professor Spencer 
obtained several photographs of this peculiar monument, which
