Mr. A. Lennox Stanton and Mr. Theodore Stevens. — Obscured Funda- 

 mentals in the Development of Integrated Electricity Supply. 



The paper presents the case of an integrated electricity supply and refers to its 

 potential possibilities for creating employment. It points out that at present this 

 integrated electricity supply does not exist and includes twelve charts, together with 

 supplementary data, showing the trend and scope presented by the changing conditions 

 of electricity supply in Great Britain. These show : — 



1. Growth of authorised sources of electrical energy during a five-year period 

 1922-23/1927-28. 



2. Changes in the number of authorised distribution systems. 



3. The trend of changes in predominant sizes of generator units. 



4. Changes taking place in voltages of generation. 



5. The advances made in steam practice. 



6. The average cost per ton of the fuels used. 



7. The units sold to consumers under power, traction, public lighting and domestic 

 services ; the revenue pertaining thereto in percentage terms ; the average price per 

 unit sold ; the average cost of fuel per unit generated and the average total cost per 

 unit generated. 



8. The average revenue from lighting and domestic supplies per unit sold for 

 individual undertakings. 



9. The average revenue from power consumers per unit sold for individual under- 

 takings. 



10. The trend and growth of stafE and workmen employed. 



1 1 . Relevant official data of the anticipated position of electricity supply under the 

 Grid Schemes a few years hence. 



The authors draw attention to limitations laboured under in every phase of the 

 industry and show data proving that between countries there is no true basis of com- 

 parison which ignore quantitative and other qualifying factors of the greatest 

 importance. 



In conclusion, the authors put forward the development of an integrated electricity 

 supply as a pre-eminent and essential avenue, leading to the solution of many pressing 

 industrial and social problems in the national life and, touching upon proposals to 

 utilise the tidal energy of the Bristol Channel for the generation of electricity, draw 

 special attention to the necessity for a searching examination being made into all 

 its financial and contractual liabilities.

The Design of Steel Structures : — 



Mr. J. S. Wilson. — Structural Steel Design and Regidations. 



Regulations relating to the design of structures have developed from two sources : 

 partly from simple rules and guiding proportions which have been adopted with the 

 object of simplif3'ing the processes of design and to render details of design more 

 consistent, and partly to make it possible to produce designs which may be strictly 

 comparable as to strength, workmanship and durability. 



Although structural design in all materials has much in common, the paper relates 

 more particularly to steel construction. 



Rules and regulations which have been used or have been proposed, have had for 

 their object one or other of the following : — 



(1) To facilitate design, keep details consistent and eliminate personal eccentricity 

 (or genius ? ) of the designer. 



(2) To simplify manufacture and cheapen production.
