16 



ing steamers concerning their position, course, speed, and sea water 

 temperature. A total of 470 official messages were transmitted to 

 Washington, and 236 were received. It is estimated that a total of 

 252,299 words were handled during the season of 1926. (See p. 20.) 

 There is appended herewith a schedule giving the times at which 

 messages were sent and received by the patrol vessel. The schedule 

 was not adopted until after several preliminary experiments and trials, 

 so that the final draft as outlined here ought to furnish a very good 

 schedule upon which to base radio operations for next year.
