A SECOND HOLIDAY ON THE BARRIER REEF 
ISLANDS. 
(By John Nebe.) 
At the end of last year T had an opportunity to again 
visit some of the islands of the Bunker and Capricorn 
Groups of the Great Barrier Reef. This was my second 
trip to these islands, and it was one month later in the 
season than my first visit four years ago (see “ Queens- 
land Naturalist, ' Vol. VI., pp. 102-108). My time was 
limited to fourteen days ; however, I was able to make 
further observations supplementing experiences on the 
first trip. 
On the last visit we made our first camp on Fairfax 
Island and from there visited Lady Musgrave, also Hoskin 
Island, when the weather permitted. These islands are 
five to eight miles distant from Fairfax Island, but even 
a moderate south-easterly breeze can make the trips to the 
islands very unpleasant. We selected Fairfax Island for 
our camp as the best central position of the Bunker Group. 
This island, like all of the coral islands, has no natural 
fresh drinking water and the water we required had to be 
taken with us from Bundaberg. On Lady Musgrave there 
is now a small shelter shed provided with a small galvan 
ized tank. 
Of particular interest to Nature lovers is the great 
seabird life that exists on these groups of coral islands in 
the summer months. 
Fairfax and Hoskin Islands are the homes of the 
nesting Brown Gannet (Sula leucogaster ) , and these birds 
were present in great numbers. Most of the young birds
