Road- Construction Facts by 

 the Wayside 



A bulletin board 

 placed beside a 

 stretch of road 

 which is being 

 built or repaired 

 gives the passer- 

 by the method of 

 construction and 

 the reasons why 

 it was adopted. 

 The bulletin also 

 tells the tax- 

 payer what he 

 is paying for 



GOOD roads enter 

 so largely into the 

 affairs of the average 

 man in this age of the 

 automobile that a pop- 

 ular step was taken 

 when road-construction 

 facts were given to the 

 public in a new and 

 striking manner. The 

 bulletin board illustra- 

 ted is in use in and 

 about Philadelphia, 

 where the Chief of the 

 Bureau of Highways, 

 William H. Connell, is 

 telling the taxpayer 

 just what he is pa>'ing 

 for in roads. 



The bulletin tells all 

 the details of materials 

 and construction in 

 non-technical language. 

 The foundation course 

 is described, as is the 

 surface course, and the 

 surface finish. Then 

 the method of mixing 

 the materials for the 

 surface course is de- 

 scribed, and the ma- 

 terials are enumerated. 



"Troubleshooting" at Night with 

 the Aid of a Searchlight 



THE " troubleshoolers " of the Far 

 West — the linemen who brave the 

 fiercest weather to keep the telephone 

 line open at all times — have already been 

 immortalized in story. It is now the 

 turn of the "troubleshooter" of the big 

 Eastern cities to get his name into the 

 latest fiction as a hero in disguise. 



Keeping telephone lines repaired is one 

 of the most difficult of jobs. There is not 

 a day but the superintendent of con- 

 struction in every big telephone company 

 sends out his corps of linemen. 



In Pennsylvania the largest telephone 

 company has a "troubleshootcr's" equip- 

 ment which is the last word in efficiency. 

 A big motor-truck enables the men to 

 get to the particular scene of trouble in 

 a minimum of time. When the call 

 comes in the dead of night the truck 

 aids the linemen with its searchlight 

 v.'hich is thrown directly upon the spot. 

 With its aid he does the work easily.
