NEW CONCEPTIONS IN SCIENCE 



been in Cuba, or Rio Janeiro, or Cape Town, or 

 perhaps Port Arthur or Manila, he might, save foi 

 the mere question of distance, have heard clicks 

 equally well. It was perfectly clear from the start 

 that the waves are radiated in every direction. 

 How do they travel? That is what no one knows 

 precisely. Professor Fleming's views have been 

 already noted. 1 They differ only slightly from 

 Blochmann's theory that the waves follow a plane 

 of equal magnetic potential that is, that they run 

 along a kind of surface, as the ripples on a pond. 

 If either of these suppositions be true, then Mar- 

 coni's daring dream, of uniting all the colonies of 

 Great Britain to the mother-land with these in- 

 visible threads of telegraphing to South Africa, 

 or Melbourne, or New Zealand, equally with Can- 

 ada or Jamaica seems now not far from real- 

 ization. It appears merely a question of waves 

 of sufficient strength. That, in turn, depends sim- 

 ply upon the power used to reel the waves in 

 space. They could go straight around the earth; 

 and if they did, they would go eight times around 

 in a second. They have a rapid gait. 



With all this quickly comes a vision of flying 

 pulsations, coming from a thousand stations, and 

 arriving with superb indifference anywhere over
