BOTANICAL INFORMATION. 487 
Clyde take their rise and proceeding a little farther north- 
wards, the mountains terminate in precipitous cliffs, 4000 ft. 
above the settled country just below. Dry’s Bluff which is 
the north east point is 4600 feet high, and the range keeps 
nearly an equal altitude for 30 miles westward. To the 
south-east of that Bluff, it gradually runs off towards Oat- 
lands, which is 1308 feet high, where it ceases to have the 
appearance of a range of mountains. Immediately, therefore 
on reaching the top you become exposed to the full force of 
the westerly wind, which is at that altitude cold even in the 
height of summer, as compared to the temperature you had 
been enjoying in your ascent on the lee side of the range. The 
character of the vegetation also changes in a few yards; the 
Eucalypti are stunted and crooked, shewing the marks of strong 
winds. The shrubs cling close to the surfaces of the rocks, 
and in sheltered gullies and small valleys alone do the plants 
venture to erect themselves in their natural position. I as- 
cended close to the base of the Peaks mentioned by Mr. 
Laurence which must be upwards of 4000 feet high; the 
points of the peaks being a few hundred feet above the rest 
of the mountain top. I found the country sloped gradually 
towards the south and I followed one of the long, narrow 
plains which characterises this part of the mountains in that 
direction, in search of water; seven head of wild cattle were 
disturbed by our presence and ran rapidly off towards the 
south, where we followed. I never had seen the top of any 
of our mountains more dry, and it was not until after a 
diligent search for 3 to 4 miles that we found some welcome 
pools. Here we bivouacked for the night. At 6 P.m., therm. 
in the air, 49°., in the water 56°., wind S.W. From this point 
the Eastern Arthurs Lake, bore S.E. by S., distant about 6 
miles, 
17th Feb. Therm. 6 a.m. in air 46°, in water 49°.—Whilst 
my breakfast was being cooked I rambled a few yards round. 
I here perceived my two varieties of Beckia micrantha (Nos. 
306 and 815), which I at one time supposed to be distinct 
Species, were in reality mere varieties. Orites revoluta in 
fruit. Viola hederacea and betonicifolia, Acacia siculeformis
