56 THE ROYAL SOCIETY OF CANADA 



The solution of the problem of producing helium in large quan- 

 tities was, before the beginning of the war, one which would have been 

 considered by many visionary and chimerical, but through the en- 

 thusiastic support and financial aid received from the British Admir- 

 alty and from the Bureau of Mines and the Naval and Air Boards of 

 the United States, the possibility of the production on a large scale 

 has been realised.
