BOTANICAL INFORMATION. 493 
miles towards the north to ascend the summit of “ Brady's 
Look-out.” the peak which Mr. Laurence was unable to 
ascend. It is the highest land in that quarter. After a very 
fatiguing excursion, 4s all our feet were swollen from the severe 
walking on hard stony ground, we got safely to the top. On 
my way I saw a novelty among the plants ; Helichrysum acu- 
minatum? n. 944, covered the ground with a golden carpet, 
and I loaded myself with specimens ; but a few minutes after 
gathering I found all the flowers had closed up, and their 
beauty in a great measure lost. 
On the top of the peak I proceeded to take the bearings 
of Mount Wellington at Hobart Town, and other distant 
points, which were visible from my elevated station ; but you 
may judge my surprise when I found that my pocket com-

peak, I started toward Lake Arthur. A small snake was 
illed as we set out, and I only saw another during my trip. 
I was told that there are some of large size on the mountains, 
which I think possible, but I did not see any. By a large 
Size 1 mean five to six feet in length, which is large for a 
Tasmanian snake. About two miles from Lake Arthur I 
fame upon what had been an aboriginal encampment; it 
consisted merely of strips of bark laid over prostrate logs of 
Wood, so as to project a little over. Under this slight shelter 
they used to lie with very small fires in front. The bark was 
taken off the trees by separating it from the wood near the 
» and then pulling it outwards. Some of the trees had 
notches cut in them by the blacks who had ascended them in
