 Mr. Arthur Grounds, B.Sc, A.I.C, A.M.I.Min.E., opened a

'* Briquetting of Coal and other substances." 



Mr. Grounds dealt with the manufacture of coal briquettes 

 from small coal, including the utilisation of what had previously 

 been regarded as waste coal. The work of the Lignite Utilisa- 

 tion Board of Canada was outlined and it was shown how 

 Canada could, by successful treatment of the large deposits of 

 lignite occurring in the Western regions, become independent 

 of the American supplies of anthracite which have at present 

 to be imported. The production of smokeless fuels of the 

 " Carbocoal " type, and the briquetting of coals by pressiire 

 alone, a process in which no binding medium is added, were 

 described. 



The briquettes are of excellent appearance and are stronger 

 than the large coal of the same class. The manufacture of lime- 

 sand bricks, and of clinker bricks from refuse destructor clinker 

 was dealt with, together with the utilisation of blast furnace 

 slag for the manufacture of building blocks.
