PRESIDENTIAL ADDRESS. Pdf 
Industry for financial assistance to carry out further ones. 
This was granted, and I have the permission of the Execu- 
tive Committee and of my colleague to make an announce- 
ment which, though far from conclusive, rather strongly 
supports the view, based on epizoological grounds, in- 
eriminating tabanids. With the aid of our assistants, Miss 
Marguerite Henry, B.Sc., and Miss Chase, B.Sc., on three 
occasions larve, probably those of O. gibsoni, have now 
been found, in the course of dissecting several thousand 
March flies. Whilst a single worm was found in one of 
these tabanids, several were present in each of the others. 
It must be remembered that it is still quite possible that 
these larve were merely accidental infestations, but the 
fact that in two of the flies the worms had much increased 
in size is important. It is also further possible that these 
larve are not those of O. gibsom. We have also several 
calf experiments in progress, one in a fly-proof pen, from 
which helpful results may follow. A partial worm-nodule 
survey of the State, carried out chiefly by Miss Somerville, 
B.Sc., and myself, shows wide dispersion of the parasite. 
even as far as the Victorian border, with an absence, some- 
times apparently complete, of nodules in certain highly- 
situated districts, such as Bathurst and Blayney. 
The Experiments Supervision Committee of the Depart- 
ment of Agriculture——The work done by this Committee, 
quietly and unostentatiously, is little known to the general 
public, or even to those interested in agriculture, but out- 
side the Department itself. Most of the experimental work 
of the Department is controlled by this Committee. Many 
of the experiments themselves are designed in detail by its 
members, whilst others are submitted by officers engaged in 
the subject under consideration. The objects aimed at are 
a full exploitation of all aspects of the science of agricul- 
ture, avoidance of over-lapping, co-ordination of effort with
