Photograph by Frank I. Jones 



A JOB FOR A TIGHT-ROPE WALKER 



THE BRIDGE OVER MARTIN CREEK 



All the materials for color photography were in this pack; if Jones had slipped there 

 would have been no illustrations in color (pages 271 to 278) to show the members of the 

 National Geographic Society. Some of the boys hesitated a long while before trusting them- 

 selves on those wet, slippery logs. I am proud to say, however, that when Mrs. Griggs came 

 to it she marched right across, just as though it were a yard wide.
