ON THE CIRCULATION OF UNDERGROUND WATERS. 115 



The following circular form of inquiry was drawn up and approved by the 

 whole of your Committee, and nearly a thousand copies have been disti'ibuted 

 by them. But your Committee regret to report that, owing to the action of 

 certain Corporations and Companies seeking additional Parliamentary powers, 

 information has been withheld from the Committee, as well as by individuals 

 and firms ; but your Committee venture to hope that, in the event of their 

 being reappointed, these difiiculties may be overcome, and that much addi- 

 tional promised information relating to areas at present reported on will be 

 received.
