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.
