HOW A DIFFICULT PFIOTOGRAPH IS SECURED 



This rather dangerous method was necessary to take the photograph on page 129, show- 

 ing one mile of trail. Two ropes are used : one tied to a log, the other given one turn 

 around the log. The operator sits in a loop in this second rope and is lowered to a ledge 

 below, from which point the desired view may be secured. Then he climbs the rope which 

 is tied, and the second rope is pulled in as it becomes slack. Thus the operator can rest when 

 he becornes tired. The ledge in this case was 55 feet below. Had anything happened, the 

 drop would have been about 300 feet.
