  struck, 
  whilst 
  driving 
  a 
  heading, 
  at 
  a 
  depth 
  of 
  70 
  ft. 
  from 
  the 
  sur- 
  

   face, 
  and 
  about 
  700 
  ft. 
  south-west 
  from 
  the 
  mouth 
  of 
  the 
  shaft. 
  

   This 
  is 
  as 
  nearly 
  as 
  possible 
  the 
  position 
  they 
  ought 
  to 
  occupy 
  from 
  

   the 
  surface 
  indications, 
  their 
  true 
  dip 
  being 
  10°

  In 
  the 
  pit-section 
  the 
  breccias 
  exactly 
  resemble 
  those 
  of 
  the 
  sur- 
  

   face 
  except 
  in 
  colour, 
  the 
  

   matrix 
  of 
  the 
  former 
  being 
  

   bluish-grey 
  variegated 
  with 
  

   a 
  little 
  red, 
  whilst 
  that 
  of 
  

   the 
  latter 
  is 
  a 
  dull 
  red 
  

   throughout. 
  This 
  is 
  merely 
  

   a 
  question 
  of 
  weathering, 
  

   and 
  the 
  difference 
  is 
  ex- 
  

   tremely 
  well 
  shown 
  in 
  the 
  

   Swadlincote 
  section 
  pre- 
  

   sently 
  to 
  be 
  described. 
  The 
  

   iron, 
  in 
  the 
  freshly 
  cut 
  and 
  

   unweathered 
  surfaces, 
  is 
  

   mainly 
  in 
  the 
  ferrous 
  state 
  

   and 
  becomes 
  oxidized 
  on 
  

   exposure. 
  

  

  Although 
  the 
  Bunter 
  Con- 
  

   glomerates 
  are 
  seen 
  to 
  over- 
  

   lie 
  the 
  breccias 
  of 
  Newhall 
  

   Park 
  a 
  few 
  yards 
  south 
  of 
  the 
  

   railway-section, 
  the 
  actual 
  

   line 
  of 
  junction 
  has 
  not 
  been 
  

   laid 
  bare. 
  The 
  Bunter 
  has 
  

   a 
  dip 
  of 
  7° 
  to 
  10°S.63°W.; 
  

   we 
  consequently 
  have 
  the 
  

   three 
  series 
  of 
  rocks, 
  in 
  

   sections 
  within 
  a 
  few 
  yards 
  

   of 
  each 
  other, 
  showing 
  the 
  

   following 
  angles 
  and 
  direc- 
  

   tions 
  of

  In 
  the 
  neighbourhood 
  of 
  

   Swadlincote 
  and 
  Woodville 
  

   two 
  sections 
  have 
  recently 
  

   been 
  opened 
  out 
  which 
  must 
  completely 
  set 
  at 
  rest 
  any 
  doubts 
  which 
  

   may 
  still 
  be 
  entertained 
  as 
  to 
  the 
  true 
  stratigraphical 
  position 
  of 
  the 
  

   brecciated 
  series
