and a half miles through dense mulga and drooping acacia scrub, 
magnificently grassed. Mr. Keartland and Edgar, who were 
unable to complete their work this morning, rejoined the party 
after sundown. Mr. Keartland, who is a most enthusiastic orni- 
thologist, continued as usual to work until midnight in order to 
preserve all the birds obtained yesterday and those procured to-day. 
Professor Tate was occupied for several hours in arranging and 
cataloguing the plants gathered during the day’s travel. 
Monday, June 18th—Camp No. 384, Deering Creek; bar. 
27°46in., ther. 41°; height 2,351ft. The camels had divided into 
_ several small mobs this morning; consequently a somewhat late 
start was made. I was disposed to return to the bat cave with 
additional means for procuring specimens of the J/egaderma, but 
as it was represented that specimens of these animals could be 
obtained near Alice Springs I proceeded ona course of 110° 40’ 
over porcupine sandhills timbered with casuarina, mulga, mallee, 
drooping acacia, and low cassia bushes. This description applies 
to the country for three and three-quarter miles, when we reached 
a sandstone ridge, which forms part of Gardiner’s Range. ‘The 
rocks here have a dip of 85° to the north. Altered our course to 
53° 5’ over similar sandridges. At two and a half miles we passed 
several clusters of large grass trees, and at three miles crossed the 
confluence of two gum creeks near a shallow rain water hole now 
about 800yds. in length. A brief halt was made here, and through 
the combined efforts of the party several interesting botanical 
specimens were obtained. Mr. E. Giles, through not following its 
erratic course, concluded that the Carmichael’s Creek westward of 
this point was a separate geographical feature and named it Deering 
Creek. To obviate future misconception I have designated the 
eastern portion of the creek from this waterhole, near which a 
small creek junctions from the north, Carmichael’s Creek. The 
northern creek will therefore be considered as forming the upper 
tributaries of the Deering. A high mountain in the northern range 
bears 18° and is five and a quarter miles distant; this was named 
Mount Musgrave by Mr. Giles. Mereenie Bluff, the termination 
of the southern range, is twelve and a half miles distant and bears 
75° 5’; a peculiar chain of escarped mountains, forming the middle 
range, terminate in a series of abrupt bluffs, of which the western 
one is the most elevated and constitutes Mr. Giles’s Haast’s Bluff. 
After carefully perusing Mr. Giles’s detailed description of this 
peculiar feature I am convinced that the position at present 
attributed to Haast’s Bluff on existing charts is erroneous. [| Sub- 
sequent conversation with Dr. Chewings, who explored this region 
in 1885, further tended to establish my conviction.] 1 have,
