NOTES ON ENGINEERING. . 

 THE BRITISH INSTITUTE OF MECHANICAL 

 ENGINEERS. 



The Institute held its annual convention 

 the first week in August at Glasgow, Pro- 

 fessor A. B. W. Kennedy presiding. The 

 principal papers and discussions related to 



the economics of gas production and of the 

 water supply of cities as a source of hy- 

 draulic power. The list was brief but the 

 papers valuable and purely technical. Mr. 

 Biggart described the aj)plication of hy- 

 draulic apparatus in the operation of charg- 

 ing retorts and in drawing the coke. The 

 result was the doubling of the output with 

 a stated force of men. Some 200 of the 

 machines described are ah-eady in use. If 

 applied to the whole manufacture in Great 

 Britain, the estimated saving would be some 

 $2,000,000 annually on eight millions of 

 tons of coal. Glasgow and other great 

 cities have them in use. The manager of 

 the Glasgow works stated that the machines 

 used in their works on a half-milliou tons 

 of coal annuallj' are in use night and day 

 and give no trouble whatever. 



Mr. Ellington described the existing sys- 

 tems of hydraulic transmission of power in 

 Glasgow and Manchester, where pressures 

 of 1120 pounds per square inch had been 

 adopted ; the customary figure being 700 to 

 800 . Their method of transmission was suc- 

 ceeding admirably in intermittent work, 

 and especially for packing presses. This 

 power was in use, here and there, in London 

 for operating dynamos. The charge for 

 water is equivalent to threepence per brake 

 horse power per hour. In South America 

 this method has been afyplied in extensive 

 drainage. 



THE CONGRESS OF SANITARY ENGINEERS 

 AND ARCHITECTS. 



Reports of the work of Congress held 

 recently in Paris and attended by foreign 

 as well as French professionals indicate 

 that much remains still to be done to com- 

 plete a modern satisfactory system. More 

 questions were propounded than answered, 

 by far, and many schemes proposed bj^ 

 members were found impracticable by those 

 actually engaged in such work. Much was 

 said of methods of economizing water with-
