At present there is a considerable amount of industrial 

 waste, because it is believed that it will not pay to be 

 utilised. Some of these avenues of waste I shall refer to 

 subsequently. 



The chiefs of most of our industries are not scientific. 

 They are purely business men, and business has little time 

 for science. There are some exceptions such as the Colonial 

 Sugar Refining Co., which recognises science and which 

 has risen to the pre-eminence that it has attained largely 

 through scientific methods of work and finance. The com- 

 pany trains its young men in its own chemical laboratory; 

 they come for a course of microbiology in my laboratory, 

 then tliey go to the University for courses in various sub- 

 jects which will augment their scientific training, and make 

 them more efficient chemists. The company knows that it 

 pays to train its assistants in this manner, and the methods 

 of the company should be an object lesson to every Aus- 

 tralian manufacturer. 



A scientific man will rarely ever be a commercial man, 

 and there are few large industries which would place its 

 chief scientific worker on a par with its chief manager. 

 Even in the Government service scientific workers are not 

 on a higher level than the clerical staff. For the nation to 

 progress this must be altered, but I am afraid this will not 

 occur until the people, as a whole, are imbued with a more 

 scientific spirit. And for this to take place we must start 

 at the root of the matter and have more science taught in 

 our schools. Once a scientific spirit is aroused, more 

 advantage will be taken of the scientific teaching available 

 in the secondary schools and technical colleges, and the 

 leaven having started to work, the nation will in time be 

 benefited. 



The value of Science. 

 As a people, we rely upon the Government for guidance 

 and assistance, but the Government is a business pure and
