APPENDIX B LXI 



Methane 80 per cent. 



Ethane 12 



Nitrogen 8 



It was found, however, on operating with this gas that the percentage 

 assigned to methane really included a considerable proportion of 

 gasoline, pentane, and butane as well. The helium content of the 

 gas was found to be 0.34 per cent. 



(b) Alberta Gases. — Gas taken from the mains leading from the 

 Bow Island supply to Calgary was found to be quite free from the 

 heavier hydrocarbons. At times it contained slight amounts or 

 water vapour and occasionally a trace of carbon dioxide as well. 

 Its approximate composition is given under I.

One well in particular, namely. No. 25 Barnwell, which has recently 

 been driven, and now supplies gas to the system, was found to have 

 a product of the composition II. 



(c) New Brunswick Gases. — Some natural gases obtained from 

 wells struck near Moncton, New Brunswick, Canada, were examined 

 and found to have the following composition: 



Methane 80.0 per cent. 



Ethane 7.2 



Carbon dioxide None 



Oxygen -None 



Nitrogen 12 . 8 per cent. 



Helium 0.064 " " 



An interesting observation was made in connection with natural 

 gases obtained from Pitt Meadows, Fraser River Valley, and Pender 

 Island, in the Gulf of Georgia, British Columbia. Both these gases 

 were found to have a nitrogen content of more than 99 per cent. 

 The lecturer pointed out how this nitrogen, if it should be found to 

 exist in large quantities, might be used as a basis for the manufacture 

 of explosives and artificially made fertilizers. A market for such 

 products lay near at hand in the Fraser Valley, in the Sacramento 

 Valley, and also in China.
