mining.  The  coal  thus  obtained  was  crushed  and  thoroughly  mixed, 
then  quartered  and  opposite  quarters  rejected.  This  process  was 
repeated  until  the  sample  was  reduced  to  convenient  size.  It  was 
then  inclosed  in  a  galvanized- iron  can  holding  about  one  quart  and 
sent  within  a  few  days  to  the  laboratory  for  analysis.  In  nearly  everj' 
case  the  sample  was  collected  by  or  under  the  observation  of  one  of 
the  parties  engaged  in  the  survey  of  the  quadrangle.  It  is  confi- 
dently believed,  therefore,  that  each  sample  fairly  represents  the 
seam  at  the  point  from  which  it  was  obtained.  The  samples  in  analy- 
ses Nos.  11,  12,  and  13  were  taken  by  an  agent  of  the  Louisville  and 
Nashville  Eailroad,  and  presumably  were  impartially  taken.  They 
are  published  through  the  courtesy  of  Mr.  J.  C.  Maben,  jr.  Analyses 
Nos.  3,  G,  and  9  were  furnished  by  the  Tennessee  Coal,  Iron  and  Kail- 
road  Company,  and  analysis  No.  10  by  Dr.  G.  B.  Crowe.
