  the 
  description 
  of 
  the 
  glacial 
  deposits 
  on 
  the 
  west 
  side 
  of 
  

   Hudson 
  Bay. 
  The 
  oldest 
  continental 
  glacier 
  was 
  the 
  Patrician, 
  

   followed 
  by 
  the 
  Keewatin, 
  and 
  finally 
  the 
  Labradorean. 
  Thir- 
  

   teen 
  post-glacial 
  Hudson 
  Bay 
  shore-lines 
  are 
  described, 
  ranging 
  

   from 
  190 
  to 
  600 
  feet 
  above 
  the 
  present 
  sea-level.

  Sixth 
  Annual 
  Report 
  of 
  the 
  Director 
  of 
  the 
  Bureau 
  of 
  

   Mines, 
  Van. 
  H. 
  Manning, 
  for 
  the 
  year 
  ending 
  June 
  SO, 
  1916. 
  — 
  

   As 
  will 
  be 
  remembered, 
  Dr. 
  Joseph 
  A. 
  Holmes, 
  under 
  whose 
  

   direction 
  the 
  United 
  States 
  Bureau 
  of 
  Mines 
  took 
  shape 
  and 
  was 
  

   developed 
  to 
  a 
  high 
  degree 
  of 
  efficiency, 
  died 
  on 
  July 
  13, 
  1915, 
  

   and 
  his 
  place 
  was 
  taken 
  by 
  the 
  present 
  Director, 
  Dr. 
  Van. 
  H. 
  

   Manning, 
  who 
  now 
  presents 
  the 
  annual 
  report 
  for 
  the 
  year 
  end- 
  

   ing 
  June 
  30, 
  1916. 
  The 
  work 
  of 
  the 
  Bureau, 
  as 
  heretofore, 
  is 
  

   concerned 
  perhaps 
  first 
  of 
  all 
  with 
  efforts 
  to 
  insure 
  the 
  health 
  and 
  

   safety 
  of 
  the 
  miners. 
  It 
  is 
  stated 
  that 
  during 
  the 
  year, 
  8,400 
  

   miners 
  were 
  trained 
  in 
  mine 
  rescue 
  and 
  first 
  aid 
  ; 
  numerous 
  acci- 
  

   dents 
  were 
  investigated 
  and 
  a 
  large 
  number 
  of 
  men 
  rescued. 
  

   Farther, 
  the 
  health 
  conditions 
  in 
  mining 
  towns 
  have 
  been 
  inves- 
  

   tigated, 
  as 
  regards, 
  for 
  example, 
  the 
  presence 
  of 
  the 
  hookworm 
  in 
  

   California 
  mines, 
  and 
  the 
  prevalence 
  of 
  tuberculosis 
  in 
  Montana, 
  

   and 
  pathological 
  conditions 
  elsewhere. 
  

  

  The 
  Bureau 
  is 
  also 
  actively 
  engaged 
  in 
  endeavoring 
  to 
  accom- 
  

   plish 
  a 
  greater 
  degree 
  of 
  economy 
  in 
  the 
  various 
  mining 
  and 
  

   metallurgical 
  processes. 
  Perhaps 
  the 
  most 
  important 
  of 
  these 
  

   are 
  concerned 
  with 
  the 
  fuel 
  supply 
  of 
  the 
  country. 
  It 
  is 
  shown 
  

   that 
  the 
  petroleum 
  industry, 
  which 
  in 
  1915 
  produced 
  over 
  

   281,000,000 
  barrels, 
  valued 
  at 
  about 
  $180,000,000, 
  or 
  over 
  65 
  per 
  

   cent 
  of 
  the 
  total 
  for 
  the 
  world, 
  needs 
  a 
  most 
  thorough 
  investiga- 
  

   tion 
  as 
  to 
  the 
  economy 
  of 
  production 
  and 
  elimination 
  of 
  waste, 
  

   since 
  it 
  is 
  estimated 
  that 
  the 
  known 
  supply 
  is 
  likely 
  to 
  be 
  

   exhausted 
  in 
  less 
  than 
  thirty 
  years, 
  at 
  the 
  present 
  rate 
  of 
  produc- 
  

   tion. 
  Economy 
  in 
  coal 
  mining 
  is 
  not 
  less 
  important, 
  as 
  well 
  as 
  

   the 
  attainment 
  of 
  the 
  most 
  efficient 
  results 
  in 
  the 
  use 
  of 
  the 
  fuels. 
  

   Much 
  is 
  being 
  done 
  now 
  in 
  these 
  directions, 
  but 
  a 
  more 
  liberal 
  

   supply 
  of 
  funds 
  is 
  called 
  for, 
  in 
  order 
  to 
  accomplish 
  the 
  best 
  

   results. 
  As 
  another 
  example 
  of 
  the 
  activity 
  of 
  the 
  Bureau 
  to 
  be 
  

   mentioned 
  is 
  the 
  extraction 
  of 
  several 
  grams 
  of 
  radium 
  from 
  car- 
  

   notite 
  ore 
  at 
  the 
  Denver 
  plant, 
  this 
  being 
  accomplished 
  at 
  an 
  esti- 
  

   mated 
  cost 
  of 
  $40,000 
  per 
  gram.
