Miss Coxen and Ken Harvey and party to observe Bird 
life. A grand tea was enjoyed by everybody and the 
day’s experiences were discussed and specimens exam- 
ined afterwards. 
On Saturday, we had an early breakfast as every- 
one was eager to get a start on the track to the famous 
Blue Lake. About 25 made the trip along a track which 
was well defined and through the bush all the way. 
After reaching the Lake (the colour IS blue, as blue as 
the sky) some walked further, crossed the swamp and 
saw the site on the ocean beach where the black metallic 
sands are being investigated. The distance walked was 
about 16 to IB miles and all agreed it had been a very 
pleasant day. 
On Sunday, the majority of the party spent a full 
day visiting the Brown Lake (Lake Carroora) and 
appreciated the offer of one of the residents to act as 
guide. 
On Monday there was no planned outing, as pack- 
ings up had to be done in readiness for leaving at 1 p.m. 
The trip back across the bay was in daylight and 
in sunshine, when we could see all the points of interest 
including Peel. Ooochie Mudlo and St. Helena Islands, 
with Cleveland and Wynnum on the mainland. 
Reaching Brisbane about 5 o’clock brought to an 
end a profitable and enjoyable week-end. 
NOTE ON THE MOSQUITO FAUNA OF THE 
DUNWICH AREA 
By ELIZABETH N. MARKS 
The Dunwich area can be a rich and happy hunt- 
ing ground for the student of mosquitoes, but he must 
be prepared to be disappointed since on some occasions 
very few will be found. The summer months. Nov- 
ember-February. appear to be the most favourable for 
collecting, but it seems probable that this is influenced 
by rainfall, at least as much as by temperature. Twenty- 
eight species of mosquitoes are known to occur about 
Dunwich, some of them being common forms widely 
distributed elsewhere. The domestic pest species Aede s 
aegypti and Culex fatigans are found in the residential
