QUALITY    OF    COAL. 
Ten  samples  of  coal  were  collected  from  mines  in  this  region.  The  samples  were  taken 
with  great  care,  pulverized  and  quartered  in  the  mines,  and  sent  in  sealed  cans  to  the 
chemical  laboratory  a  of  the  United  States  Geological  Survey  coal-testing  plant,  St.  Louis, 
Mo.,  where  the  following  analyses  were  made:

''The  air-drying  losses  in  the  Adaville  and  Lazeart  coals  do  not  appeal-  to  lie  entirely  comparable. 
cThis  is  just  below  the  Laramie  coals  and  may  be  said  to  represent  them. 
I.  Michigan-Wyoming  Oil  Company's  mine,  NW.  |  see.  35,  T.  17  N.,  R.  120  W.  Sample  taken  40  feel 
from  mouth  of  mine.  Bone  1  inch  thick  6  inches  from  the  roof  and  4  inches  thick  18  inches  from  the 
roof,  omitted  in  sampling.     Sample  represents  total  thickness  of  bed. 
II.  Rocky  Mountain  Coal  and  Iron  Company's  mine  No.  5,  Almy,  Wyo.  Sample  taken  3,000  feet 
from  mouth  of  slope  in  room  5,  entry  12,  and  represents  lower  8  feet  of  24-foot  vein.  Upper  part  of  bed 
contains  numerous  partings. 
III.  Lazeart  mine,  SE.  {  SW.  J  sec.  8,  T.  15  N.,  R.  118  W.  Sample  taken  15  feci,  from  mouth  of  slope. 
Bed  is  30  feet  thick  and  sample  represents  upper  13  feet. 
IV.  Adaville  mine,  NE.  i  SW.  \  sec.  20,  T.  21  N.,  R.  HOW.  This  sample  is  from  a  tunnel  driven  hori- 
zontally across  the  coal  bed,  which  is  here  84  feet  thick  and  dips  18°  W.  Tunnel  is  6  feet  high  and  sample 
was  collected  by  means  of  vertical  cuts  every  50  feet.  This  sample  represents  slightly  less  than  half 
the  thickness  of  the  bed.     There  are  no  partings  and  the  coal  is  remarkably  uniform  throughout. 
V.  Union  Pacific  Coal  Company,  Cumberland  No.  1  mine,  Cumberland,  Wyo.  Sample  from  the  face 
of  seventh  entry  south,  2,100  feet  west  and  2.000  feet  south  of  mouth  of  mine.  Sample  represents  entire 
bed. 
VI.  Uiamondville  Coal  and  Coke  Company,  Diamondville  No.  1  mine.  Sample  from  room  No.  45, 
entry  No.  1  north,  100  feel  west  and  3,300  feet  north  of  mouth  of  mine.  A  clay  seam  4  inches  thick  I  foot 
from  roof  was  omitted  in  sampling.     Coal  at  th  \  point  sampled  is  regarded  as  best  in  the  mine.
