The Queensland Naturalist. 
5 
moner varieties, and numbers of others, including small 
flocks of blue-mountain and greenie parrots, the blos- 
soms being somewhat scarce. They will, however, be 
more numerous soon. 
Some of the party took toll of the Geebungs (Per- 
soonia) which are in full fruit, and also a few stray 
berries of the Midgin bush (Myrtus tenuifolia, var lati- 
folia). This bush in places covers many acres, and being 
very prolific, in past days added much to the natives' 
larder. 
Our track brings us, ere lunch, by open fiats and 
•thickly-wooded hills, to the Blue Lake, known to the 
natives as “Kaboora.” 
Clear and bluish in colour, and reputed to be very 
•deep, — it is certainly far from shallow — surrounded by 
thickly forested clad hills, it has no level banks, for 
the hillsides run straight down into the water, and afford 
reeds but little opportunity to grow. It is, however, 
margined with ferns, both climbing and otherwise, and 
sphagnum moss in places. Shaped somewhat like the 
letter L broadened out, and withal not having the extent 
of Boomera, it is one of the most beautiful of lakes, 
a gem only seen by the favoured few, or by those hardy 
•enough for a good day's walk. 
The presence of fish seems to be indicated by a pair 
of hovering eagles, and a pied cormorant. 
Whilst admiring the scene one is reminded that 
•some years ago the idea was mooted to utilise the waters 
of the Stradbroke Lakes as a supply for Brisbane. 
Surveys and reports were made, but for various reasons 
the idea was eventually abandoned. 
Unlike Boomera, which has no visible outlet, the 
Blue Lake has a small stream issuing from it at its 
south-eastward corner, and some half-dozen of the more 
energetic set off to follow this to its outlet from the 
hills. The track follows the V-shaped gorge near the 
stream, which is shaded by a few scrub trees, also the 
swamp tree-fern, and a few others, while mosses and 
aquatic plants all help to make one wish for leisure for 
a more detailed examination. 
In about a mile a small amphitheatre is reached, 
terminating the pass through the line of hills bordering 
the 18-Mile Swamp on its western side: indeed, I believe 
it is the only \ow level pass in the whole distance.
