PUMPING MACHINERY OF THE WATER AND SEWERAGE BOARD. LXIII. 



to a river and the suction head was practically about 10 

 feet, while the delivery head was 230 feet. The pump had 

 been started with a load measured practically by the 10 

 feet suction head. It was then gradually speeded up to 

 the essential speed necessary, being worked by a 245 HP. 

 electric motor. During the time of getting up speed it 

 had been charging a long line of 22 inch main up a mountain 

 side, and it was a long time before the head load was dis- 

 tributed on both sides of the impeller to overcome the 

 thrust. The builders had stated that the magnetic pull 

 should be availed of to overcome the thrust, but this did 

 not work out in practice. 



As it was getting very late, Mr. Furniss had, rather 

 abruptly, to conclude his remarks ; he thanked those present 

 for the interest they had taken in his paper. Much of the 

 matter it contained had, he said, been prepared in Mr. 

 Smail's department of the Water and Sewerage Board. He 

 did not claim that much originality was shown in it, but 

 it had been the outcome of the pursuance for years of a 

 study that was very interesting to him, owing to the fact 

 that he was a pumping engineer. 



The President (Mr. Keele) said that it was a great pity 

 there had been so few present, but those who had attended 

 had compensated for this by the great interest taken in the 

 subject, and the discussion had been very instructive to all. 

 One duty now remained to him, to heartily thank Mr. 

 Furniss for his very interesting paper, and for the instruc- 

 tive discussion it had led to. A vote of thanks had been 

 accorded to the lecturer on the occasion of the reading of 

 the paper, but he was sure that those present would only 

 be too glad to renew their thanks again. 



This was carried by acclamation and the proceedings 

 terminated.
