198 REPORTS ON I-HE SfAM OP SCIENCE.— 1916. 



Similar inquiries will be instituted in regai'd tO preSeht-day practice 

 and results in relation to (1) iron foundries, (2) manufacture of wrought 

 iron, and (3) specialised steel industries. 



Two members of the Sub-Committee specially connected with the 

 ceramic industry have undertaken to prepare a memorandum showing 

 the average present practice and the possible margins of fuel economy in 

 relation to that industry, and information is invited by the Sub-Com- 

 mittee relative to glassworks and brickworks. 



The Sub-Committee desires to state that all information com- 

 municated to it by individual manufacturers will be regarded as con- 

 fidential,' and will be used merely as a basis for arriving at an approxi- 

 mate estimate of the present average fuel consumption per unit of 

 output in the particular industry to which the information relates. 



D. 



Power and Steam Raising Sub-Committee. — Mr. C. H. Merz 

 (Chairman), Lord Allerton, Mr. J. A. P. Aspinall, Dr. Dugald 

 Clerk, Mr. S. Z. de Ferranti, Sir Robert Hadfield, Dr. H. S. 

 Hele-Shaw, Mr. W. W. Lackie, Mr. Michael Longeidge, Mr. 

 Robert Mond, Hon. Sir Charles Parsons, Professor Ripper, 

 Mr. R. P. Sloan, Mr. C. E. Stromeyer, Professor Threlfall, 

 Mr. G. Blake Walker, and Mr. B. W. Woodhouse. 



The special duty of this Sub-Committee is to investigate the 

 economies in fuel which would result from the use of irapi'oved methods, 

 and it has been decided to deal with the subject under the following 

 heads : — 



(1) To consider (a) the amount of fuel consumed, and (b) the 



corresponding power developed in the United Kingdom 

 under the following heads : Factories, Mines, Railways, 

 Ships, and Steam Raising for other purposes than power. 



(2) To consider the present position of central electrical power 



plants and gas undertakings as regards power supply. 



(3) To discuss the relative merits of the present methods for 



producing power by steam, gas, oil, and petrol engines 

 respectively. 



(4) To investigate the possible saving of fuel which might be 



effected (a) by improved plant, (b) by greater centralisa- 

 tion of power production, (c) by co-ordination with metal- 

 lurgical and other manufacturing processes, (d) by some 

 measure of public control, (e) by better supervision, and 

 (/) by the use of inferior grades of fuel which are at 

 present wasted. 



While, on account of the magnitude of the subject and the amount 

 of investigation involved, it is not possible at present to submit any 



8 It is suggested that all such information should be sent in the first instance to 

 Professor Bone (Chairman of the General Committee), at the Imperial College of 

 Science and Technology, London, who will classify and summarise it under either 

 alphabetical letters or numerals in such a way that the names of the manufacturers 

 or firms concerned will not be divulged to any of the members of the Committee.
