AMERICAN FORESTRY 



"The first poles were 

 cut on May 21, and the 

 tower was completed 

 and in use on June 20. 

 The time spent in cut- 

 ting and peeling logs 

 and constructing the 

 tower amounted to less 

 than 24 working days 

 of 8 hours each, for a 

 crew which averaged 

 five in number. In ad- 

 dition, at wo- horse 

 team was used 9 days. 



"Four galvanized- 

 wire cables ^ in. in 

 diameter will be added 

 as guys. A copper 

 cable reaching up and 

 over the center of the 

 tower will follow one 

 leg to the ground and 

 serve as a lightning 

 arrester."
