various observations. This part of my work, as I have no assistant, 
occupied me until midnight. In the afternoon heavy clouds 
appeared and thunder rumbled in the distance, but only a few 
drops of rain fell. Mr. Keartland was employed throughout the 
day in skinning and preserving birds, which have been fairly 
numerous during the last few days. A large number of rock 
pigeons were shot at this camp. 
Thursday, June 21st.—Camp No. 86; bar. 29°69in., ther. 40°. 
During the early part of the night a few drops of rain came down. 
This morning I moved the camp some seven and a half miles down 
the creek in a northerly direction, and stopped at a large rain 
water hole, called Oondoomoolla. The course at starting was 
24° 30’, through the gap,.a narrow pass some three-quarters of a 
mile in length, and was then altered to 51° across a small plain. 
At one mile we passed through a second gap in a higher range, 
trending nearly east and west. The latter range is the continuation 
of that in which Mount Musgrave and Mount Tate are situated. 
All these ranges are of quartzite formation, and run in parallel 
ridges. Near the entrance of the second gap and at the confluence 
of two creeks permanent pools of water were found. Teatree, 
frequently an indication of permanent water, grows in profusion 
along the several channels of the creeks. Leaving the range, in 
another mile we entered on a well-grassed mulga plain, on which 
both saltbush and cotton-bush flourish. At two and three-quarter 
miles, on a bearing of 9°, I ascended a small ironstone rise, and 
obtained a fine view of the surrounding mountains. Now changed 
the course to 848° 50’, travelling through well-grassed mulga 
scrub for two and three-quarter miles to Oondoomoolla Waterhole. 
The camp having been formed, preparations for an extended trip 
to what has been erroneously termed Haast’s Bluff were made. 
Professor Tate and I set out on horseback to examine some ranges 
bearing 72° 10’ and four miles distant. Travelling over splendidly- 
grassed saltbush plains until near the ranges, we came to an 
exceedingly dense belt of mulga scrub. Here, for the first time 
during the entire trip, a few quartz reefs were discovered. We 
returned to camp at sundown. 
Friday, June 22nd.—Camp No. 37, Oondoomoolla Waterhole ; 
bar. 27°82in., ther. 27°; height 1,969ft. Leaving the main camp 
at this waterhole in charge of Mr. Keartland, I proceeded, with 
Professor Tate, Dr. Stirling, the two Government prospectors (C. 
Pritchard and W. Russell), Taylor, and two black boys, taking 
nine camels and two horses, with four days’ rations, towards the 
high mountains hitherto styled Haast’s Bluff. Our course was 
359° 20’ for three-quarters of a mile to Annaldie, another large
