water’’ (Middleton’s Fish Ponds), now, however, quite dry. Altered 
my course to 177° 50’ for two miles to a stockyard and well on the 
Petermann Creek, near the eastern termination of the Levi Range. 
This well appears to be about 60ft. deep, and at present contains. 
about 80ft. of water. Several small clay waterholes near the 
stockyard do not now contain any water. Petermann Creek joins 
the Palmer river a few miles to the eastward. Once more altered 
course, now so as to strike Undia Creek near its junction with the 
Petermann. At twelve and a half miles, over well-grassed country, 
I crossed Undia Creek, and at fifteen and a half miles I reached 
the Depot Camp, No. 25, having travelled altogether twenty-eight 
miles. Mr. Belt, with the pack camels, had previously arrived. 
Professor Spencer and Dr. Stirling came in towards evening, under 
‘the guidance of my black boy, whom I sent back at sundown for 
Professor Tate. Both the professor and his guide returned to camp. 
in about an hour’s time. Mr. C. E. Cowle reported himself to me 
on my arrival. From his knowledge of this country, and his ex- 
perience with the aboriginals of this region, he will be a valuable 
addition to the party. The’ expedition now consists of eighteen 
members, with twenty-six camels and eleven horses. 
Thursday, June 7th.—Camp No. 25, bar. 28°16in., ther. 52°. A 
somewhat late start was made with the pack camels. Mr. Watt 
and Professor Tate, having been provided with horses, proceeded 
with Mr. Cowle to Gill’s Range, for the purpose of examining 
certain fossil deposits recorded by Mr. H. Y. L. Brown, the 
Government Geologist, as existing in that neighborhood. I then 
set out on a bearing of 265°, following the course of the Petermann. 
Creek. With three miles completed i found myself at the foot of 
Mount Levi, and the termination of the Levi Range. Accordingly 
I altered my course to 257°, crossing the Petermann in one mile. 
At two miles I passed several rain water holes in the creek, and. 
then changed the course to 257° 10’, in the direction of Gill’s 
Range. With one mile covered on this line I passed Mr. E. 
Giles’s ‘“‘ permanent waterhole”’ and marked tree. I do not regard. 
the waterhole capable of affording a perpetual supply. The indi- 
cations of permanency described by Mr. Giles are only saline 
deposits from the rocks, due to evaporation. A quarter of a mile 
further on I struck the junction.of Petermann and Trickett’s. 
Creeks. From here a fine open plain, splendidly grassed, with 
an abundance of salt and cotton bush, extends to the foot of Gill’s. 
Range. At three anda half miles I arrived at the south-eastern 
point of this range. Here | awaited the coming of the main party, 
and then camped half a mile to the south, on Trickett’s Creek. In 
the afternoon I proceeded with Professor Tate and Mr. Watt to:
