 and thence also by wire to the sending station at Rocky Point, Long

up at Cupar, Scotland, and transmitted by wires to London from which 

 point they go by the usual wire connections to the subscriber in England 

 or on the continent. 



The answering voice waves are transmitted from the European 

 subscriber by wire to London and thence by wire to Rugby, England, 

 at which point they are radiated into space. The waves are picked up 

 at Houlton in the northern part of Maine and transmitted by wires 

 to New York City and thence by wires to the American subscriber. 



You will note that the east and westbound radio systems are entirely 

 separate from each other. Please note also that the receiving points 

 in both countries are carried as far north as convenient — to Houlton, 

 Maine, in this country, and to Cupar, Scotland, in the British Isles. 



The radio and wire plant in Great Britain is owned and operated by 

 the Post Office Department of the British Government. 



As a supplement to the long waves there is a short wave circuit 

 being formed which is so far only partially in use. In Fig. 3 the heavy 

 lines show the long wave and the lighter lines the short wave routing. 

 The short wave circuit from the United States to London was em- 

 ployed as an emergency routing during the severe static season last
