photograph it. Harry the black boy I dispatched to the slopes of 
Mount Sonder to procure additional specimens of a new heather 
/ Epacris ), imperfect specimens of which were obtained yesterday 
by Messrs. Belt and Cowle. Received a report of the journey 
to Ayers Rock from the several members who accompanied Mr. 
Cowle and marked their route on the map. Computed the altitude 
of the various mountains in this neighborhood, which give the 
following results : — Mount Heughlin, probably the highest hill in 
Central Australia, 4,786ft. above sea level; Mount Zeil, 4,040ft ; 
and Mount Sonder, 4,496ft.in height. The prospectors assiduously 
tested several localities in the vicinity of this camp without obtain- 
ing the slightest indications of any minerals. An enormous carpet 
snake, fully 8ft. in length, was captured during their researches. 
The name of Mount Heughlin has been erroneously applied to a 
high hill west of the Mount Heughlin of Mr. E. Giles. I have, in 
properly rearranging the names of the several hills, expunged the 
name of Mount Razorback, which is Mr. Giles’s Mount Zeil, and 
designated the high mountain west of Mount Heughlin, visited by 
me in 1878, Mount Chewings. 
Friday, June 29th.— Bar. 27°61in., ther. 20°. Mr. Cowle, who 
had remained with us over night once more departed for [lamurta 
this morning. Directing the caravan to return on our former 
course some four miles, I started on a bearing of 138° 10’ through 
well-grassed mulga scrub with occasional low spinifex undulations 
(micaceous schist). At three and a quarter miles I ascended a tent- 
shaped hill (quartzite) for the purpose of obtaining the necessary 
bearings to surrounding hills and ranges. Continued on a bearing 
of 301° 20’ for one and three-quarter miles to a low hill, passing 
several small quartz reefs; then 295° 40’ for one and a quarter 
miles, and 268° for three and a half miles to a large tributary 
creek (the Davenport) of the Finke river. This was followed by 
the whole party on a bearing of 241° for one mile and 226° 30’ for 
two and a quarter miles to a gorge or pass in the northern range 
of Mereenie Valley. I have named this gorge Goyder’s Pass, after 
G. W. Goyder, Esq., C.M.G., late Surveyor-General of South Aus- 
tralia. It furnishes the only possible approach to Glen Helen 
Station now that the Finke Gorge, twenty-one miles to the east- 
ward, has become impassable. Continued due south through the 
Pass for half a mile; then altered our course to 102° along 
Mereenie Valley, which is here about a quarter of a mile in width 
and hemmed in on either side by high precipitous ridges. The 
bed of fossiliferous limestone previously noted in this valley again 
appears here. At one mile and two and a half miles we crossed — 
two small gum creeks trending westward, and at four miles the
