broken blade. However, grinding is still noticeable. 
The other implements found comprised a mussel-shell 
knife, and a number of scrapers, including several side 
and end scrapers, and also one fine example of a half- 
circular side scraper, which has been very well flaked. 
Another is a small triangular point with a ridged 
back which is a common stone implement right through- 
out Moreton Bay and the Brisbane district.

GEOLOGICAL NOTES. 
The excursion this year added little to the observations 
made on the previous visit to the locality. This Avas due 
in part no doubt to the smaller number of geologists, and 
in part to the comparative inactivity of those present, but 
mainly to the fact that on the previous visit we had 
“ picked the eyes” of the sections already known to be of 
interest. That is to say we then went to look at sections 
rather than look for them. This time we hoped to find 
new sections. As was expected, the geology did not seem 
to have changed much in the three years’ interval. Keen 
readers may refer to the notes made then as still 
applicable. 
The chief geological problem, and a very important 
one, is the relationship of the widely differing types of 
volcanic rocks to one another and to the Jurassic strata 
on which they rest and into which they have been in- 
truded. 
Sir Roderick Murchison once told the young Geikie 
that good legs were more important to a geologist than his 
head. 
There is fine scope in the Upper Albert region for a 
geologist, but with good hands and heart and head, as well 
as legs, if he is to do justice to the task. 
We followed up the river for a few miles, but only 
met with volcanic rocks either in situ or in the river- 
borne material. Some of the party picked up nice pieces 
of green jasper- — probably the infilling of steam holes in 
the lava flows. 
On another day, on the ridge separating the Albert 
from Widgee Creek waters, or rather in a gully on the 
Widgee Creek side, we noted a coal seam in the sand- 
stones forming the ridge. On the previous visit we saw 
seams in Widgee Creek and in the Albert River.
