The Queensland Naturalist May 194S 
years later (1886) lie was the principal mover in the for- 
mation of a Field Naturalists’ Section of the Royal Society, 
which lasted until 1894. 
Early in 1892 a Society was formed under the name 
of The Natural History Society of Queensland, and Mr. 
Tryon was its first President. Unfortunately, the Society 
only existed for about three years. 
The natural history movement in this State went to 
sleep for a few years, and was revived in March, 1906, by 
Mr. Tryon and a few other enthusiasts, when the present 
Club was inaugurated. Mr. Tryon was a tower of strength 
to the Club in its early years, and maintained his interest 
in it. 
When, in 1888, a Royal Commission was appointed in 
New South Wales to report upon various schemes for the 
extermination of rabbits, Mr. Tryon was one of two 
Queensland representatives, and in this capacity he did 
special work. 
His work in connection with the extermination of 
prickly-pear does not seem to have been fully recognised 
by tlie public. He was the first to suggest the possibility 
of using natural enemies against it at a time when the 
prospect of combating the pear looked extremely black, 
and his suggestion led to the ultimate conquest of the pest. 
When a commission was sent round the world by the 
Queensland Government in search of natural enemies, Mr. 
Tryon was one of its members. 
Mr. Tryon published more than 150 reports and 
papers dealing with entomology, botany, plant pathology 
and other scientific subjects — a record that it would be 
difficult to equal. Among these were numerous papers 
given to the old Natural History Society and the present 
Club. 
Henry Tryon was a clever man who did great work 
for this country.
