by the passengers, as is indicated by the number of calls completed 

 each day, particularly on the return trip. A similar number of test 

 and demonstration calls was made during the voyage. The calls 

 were completed without undue delay, there being only one ship in- 

 volved, and a fairly high grade of communication was obtained. 



In conclusion it will be realized that the solution of the techincal 

 problem of ship-to-shore telephony is now well in hand and has been 

 carried to the point of having proved the practicability of giving this 

 service. Further problems are naturally arising in carrying the devel- 

 opment into more general effect, particularly operating problems and 

 those concerned with the international coordination of the service. 

 The indications are that the larger transoceanic ships will be rather 

 generally equipped for telephony and that the service will become one 

 of permanent value in the maritime field.
