74 PHOTO-TELEGRAPHY 



was only about two -thirds transmitted, and the 

 result was that the photograph was only received in 

 part ; needless to say, the more important part of 

 the subject was missing, and the result was quite 

 useless for publication. 



Experiments were carried out between Berlin and 

 Paris, using one line only and an earth " return " ; 

 the current received in this way was about 5 milli- 

 amperes, and sufficient to work the apparatus satis- 

 factorily. 



A second English telautograph was begun in 

 February, and an effort was made to have it ready 

 and installed at Manchester in time to telegraph 

 down to London the finish of the Grand National 

 race at Aintree in March. A change was made at 

 the same time in Manchester, the photo -telegraphic 

 installation being removed from the office of the 

 Manchester Courier to a new office specially 

 equipped for the work. A few days before the race 

 took place the new telautograph was taken to Man- 

 chester, and through the courtesy of the Post Office 

 officials there a trunk line was put in and tested just 

 in time to enable one experimental picture to be 

 wired through. The finish of the race was taken 

 by a press photographer, and the plate taken by a 

 Daily Mirror motor car to the station at Aintree, 

 and brought thence by train to Manchester. It 

 was then developed and a fish-glue print of the 

 picture was prepared and at once wired to London.
