Per cent. 



19 analyses averaged about 45 



3 analyses averaged between 50 and 55 



2 analyses averaged between 55 and 60 



4 analyses averaged between 60 and 65 



The analyses of the creosotes extracted from five of the poles from 

 the Washington-Norfolk line were published by Von Schrenk, Fulks, 

 and Krammerer {20). Later, Rhodes and Hosford {23) published 

 independent analyses of the creosotes from the same poles and, in 

 addition, of one other creosote from the same line and of one from 

 the Montgomery-New Orleans line. The records of both series of 

 investigations are given in table 20.
