of heat through radiation, and of course a decrease in the 

 temperature through the compression of the air ; conse- 

 quently there was a certain amount of loss in such a system 

 of storage. He was of opinion that steam power at present 

 was cheaper than electricity for pumping purposes, the 

 figures for each according to his reading would be some- 

 where in the nature of .26d. per HP. per hour for dry steam, 

 including labour and everything else, and .35d. for elec- 

 tricity. He quite appreciated Mr. Selfe's point as regards 

 turning the steam into electricity and then back again into 

 pumping power, which practice he stated would only be 

 economical in the case of very large generating stations. 

 Even then, he said that the cost of transmitting tbe energy 

 would go a long way towards eating up the economy thus 

 gained. 



Mr. J. M. Smatl said that the paper had been cut down 

 to such an extent as to leave it practically without any 

 connecting links. He complimented the writer on his 

 valuable paper, because it was papers of that description 

 that were useful, not so much to the older, but to the 

 younger members of the Section. One of the points he 

 noticed about the Engineering Section was that they laid 

 themselves out specially for the younger members of the 

 profession. The old Botany engines referred to by Mr. 

 Selfe were of the old low pressure type, Lancashire boilers, 

 pressure about 40 fbs., but, as a type of British built engines 

 they compared in solidity and good work with any engines 

 that we had in later days. The next type introduced was 

 he believed, an engine designed by Mr. Norman Selfe and 

 built by Mort's Dock Engineering Co. The first of these 

 was a very elaborate engine, but it outlived its usefulness. 

 Then we had the modern type of Worthington pump, Nos. 

 1 and 2, which also did great credit to its builders, par- 

 ticularly on account of the small cost of upkeep entailed,
