PRESIDENTIAL ADDRESS. 15 



partly in the different mills in Queensland, Fiji, New South 

 Wales, and the refineries in New South Wales, New Zealand, 

 Victoria, Queensland, and South Australia. As sugar 

 manufacturing and refining are chemical processes, all the 

 different operations are checked by analysis, as are also 

 the waste products. Each mill and refinery possesses its 

 separate laboratory and staff of chemists engaged in routine 

 analytical work, the head chemist at each establishment 

 having control of the manufacture. The laboratory in 

 Sydney, which is under the direction of Mr. T. U. Walton, 

 b.sc , f.i.c., and Mr. T. Steel, p.l.s., f.c.s., controls the work 

 of the other laboratories and mills. Here also the younger 

 chemists receive their special training. Twenty-three 

 years ago the company employed only a single chemist. 



Messrs. Elliott Bros, are the principal manufacturing 

 chemists, and give employment to about 300 hands. They 

 manufacture mineral acids, sulphuric, hydrochloric, hydro- 

 fluoric and nitric acids as well as anhydrous ammonia and 

 compressed carbon dioxide. Sulphuric acid is manufactured 

 by the chamber process with all the most recent improve- 

 ments, the output being about 18,000 tons annually, Jap- 

 anese sulphur being used in its preparation, and the acid is 

 principally utilized in the manufacture of superphosphates 

 which form the basis of the chemical fertilizers, which are 

 manufactured in large quantities by Messrs. Elliott. Sul- 

 phuric anhydride is also manufactured by the ' contact ' 

 process. Messrs. Elliott Bros, are also our chief manu- 

 facturers of pure chemicals, drugs and pharmaceutical pre- 

 parations. They are also smelters of Bismuth. Elliott 

 Bros, have a similar manufactory at Brisbane. 



The Australian Drug Company are large manufacturers 

 of pharmaceutical preparations, druggists' proprietary 

 articles and storekeepers' sundries, the manufacture of 

 which articles is under competent chemical supervision.
