 work of an army of investigators, scattered over the 

 earth, but all advancing, under the invisible cap- 

 tains of a common purpose and a kindred hope, 

 towards the conquest of the unknown world which 

 lies beyond our primitive senses. 



Even the man in the street may now begin to 

 perceive its deep and practical value, and perhaps 

 feel something of admiration for the fruition of a 

 vast effort, directed not by instincts of gain and 

 greed. A high humanity breathes here, larger, if I
