more dangerous operating against fixed objects, such as harbour 

 defences, etc., in which case they could be detected from the shore 

 by submarine listening devices, such as my liquid microphone. 



I have now come to the end of my Discourse, but before closing 

 I should like to say that I think a great deal of credit is due to 

 Anschutz for the courage he displayed in being the first to attempt a 

 Gyro-Compass, knowing, as he did, the extremely feeble force that is 

 likely to result from the earth's rotation, and in the fact that the 

 instrument must be carried on a rolling, pitching, plunging vessel. 

 With us who follow it is a question over again of Columbus and 

 the egg. 



For myself, if I had known at the commencement of my acquaint- 

 ance with the Gyro-Compass, some five years ago, all the difficulties 

 that had to be encountered, I should I think have abandoned the 

 pursuit. It was a case of " where angels fear to tread."
