SCIENCE AND INDUSTRY. 
In 1911, Mr. Gepp was sent to England by the Amalgamated Zine 
Company in conjunction with the Broken Hill South and Broken Hill 
North, to investigate various processes for the treatment of slimes, of 
which large accumulations had gathered at Broken Hill. The 
solution of this problem, however, was eventually produced in Australia 
by the introduction of.the differential flotation process. 
In 1914, after being in camp for some months assisting in training 
field engineers for the Front, he went to America in connexion with 
business for Amalgamated Zine Limited, his intention being to remain 
only a few months, but was retained there for quite a period in connexion 
with various metal and munition matters. 
During the latter part of 1916, after investigating the possibilities of 
production of zine by the electrolytic process, Mr. Gepp was autho- 
rized by his company to take the necessary steps to demonstrate that 
enormous. quantities of zine concentrates available at Broken Hill, 
representing a quantity of 200,000 tons annually of metallic zinc, could 
be satisfactorily utilized for the production of high grade zinc; and 
carried out some tests on a fair-sized scale in America, and returned 
at the end of 1916 to Australia. 
Ever since Mr. Gepp’s visit to Europe in 1911 and 1912, he has been 
deeply interested in the development of the right attitude of mind and 
the right spirit between all classes of the community in connexion with 
industrial work, whether this work be in connexion with the production 
of steel or other metals, or with any other branch of industry. In this 
regard, he recently remarked:—‘I have felt very strongly that we 
cannot hope for reasonable efficiency, reasonable happiness, contentment, 
and health in the community without the leaders of industry taking 
a definite and clear attitude of helping to educate the country 
generally as well as educating themselves. The work, which has been 
followed up in specific cases by those of us who think as I do, has 
demonstrated that, just as the Australian soldier can fight well as long 
as he is led well, so Australians generally will work well as long as they 
are taken into the confidence of the leader and that everybody plays the 
game. It is only by definite co-operation and clear thinking, and by 
endeavours to reduce the wastage, such as in the case of distribution of 
_ essential commodities and bringing down the cost of living and improv- 
ing the conditions of home life, that we can hope for reasonable results 
in the future.” 
Among the visitors to the offices of the Institute last month were 
Mr. Seizamburo Shimizu, the Consul-General for Japan, and Mr. K. 
Pamaly, who is Acting Consul-General during Mr. Shimizu’s visit to 
Japan. 
Mr. A. McKinstry, B.A., M.Se., a member of the Executive Com- 
mittee of the Advisory Council, and one of the Victorian Electricity 
Commissioners, has been granted six months’ leave of absence. He 
sailed for England by the Marathon ow July 12. : 
Professor T. H. Laby has secured six months’ leave of absence from 
the Senate of the Melbourne University on account of ill-health, and 
will visit England. Professor Laby is a member of the Victorian State- 
Committee of the Advisory Council.
