  The 
  way 
  to 
  the 
  village 
  of 
  La 
  f 
  Champ 
  Raphael 
  is 
  by 
  the 
  saw- 
  

   mill 
  of 
  Bacconnier. 
  The 
  pastures 
  here 
  are 
  filled 
  with 
  charming 
  alpine 
  flowers, 
  

   and 
  surrounded 
  with 
  extensive 
  woods 
  (Bois 
  de 
  Cuze) 
  ; 
  but 
  La 
  Champ 
  is 
  a 
  miser- 
  

   able 
  exposed 
  village, 
  situated 
  near 
  the 
  heights 
  which 
  overlook 
  St 
  Andeol 
  and 
  the 
  

   valley 
  of 
  the 
  Erieux, 
  with 
  the 
  chain 
  of 
  the 
  Mezenc 
  in 
  the 
  distance. 
  The 
  eleva- 
  

   tion 
  above 
  the 
  sea 
  is 
  4409 
  feet. 
  In 
  the 
  neighbourhood 
  are 
  old 
  basalts. 
  A 
  few 
  

   miles 
  to 
  the 
  eastward 
  we 
  reached, 
  by 
  a 
  bleak 
  exposed 
  tract, 
  the 
  village 
  of 
  Mesil- 
  

   hac, 
  where 
  we 
  passed 
  the 
  night 
  in 
  very 
  wretched 
  quarters. 
  The 
  view 
  from 
  hence 
  

   to 
  the 
  north 
  is 
  similar 
  to 
  that 
  from 
  La 
  Champ 
  Raphael 
  ; 
  and 
  I 
  thought 
  the 
  moun- 
  

   tain 
  forms 
  sufficiently 
  remarkable 
  to 
  deserve 
  a 
  record, 
  which 
  I 
  have 
  given 
  in 
  

   Plate 
  V., 
  fig.

  Mesilhac 
  is 
  a 
  dirty 
  hamlet 
  of 
  but 
  a 
  few 
  houses, 
  on 
  the 
  col 
  connecting 
  the 
  val- 
  

   lies 
  of 
  the 
  Ardeche 
  and 
  Erieux, 
  and 
  is 
  at 
  a 
  height 
  of 
  3791 
  feet 
  above 
  the 
  sea. 
  A 
  

   pleasant 
  walk 
  of 
  only 
  three 
  hours 
  took 
  us 
  next 
  day 
  through 
  a 
  comparatively 
  open 
  

   and 
  accessible 
  valley 
  to 
  the 
  beautifully 
  situated 
  village 
  of 
  Antraigues, 
  where 
  we 
  

   found 
  ourselves 
  amidst 
  a 
  wholly 
  new 
  series 
  of 
  modern 
  volcanic 
  formations. 
  Oppo- 
  

   site 
  La 
  Viole, 
  a 
  hamlet 
  about 
  five 
  miles 
  above 
  Antraigues, 
  there 
  is 
  a 
  volcanic 
  sum- 
  

   mit 
  on 
  the 
  right 
  hand 
  of 
  the 
  River 
  Volane 
  ; 
  but 
  as 
  its 
  lava 
  is 
  chiefly 
  thrown 
  in 
  a 
  

   different 
  direction, 
  we 
  shall 
  not 
  at 
  present 
  describe 
  it. 
  

  

  Antraigues 
  {inter 
  aquas) 
  is 
  seated, 
  as 
  it 
  name 
  imports, 
  at 
  the 
  junction 
  of 
  

   several 
  mountain 
  streams 
  in 
  a 
  romantic 
  hollow. 
  It 
  is 
  built 
  on 
  a 
  tongue 
  of 
  granite, 
  

   formed 
  by 
  the 
  junction 
  of 
  the 
  Volane 
  and 
  Riviere 
  du 
  Mas, 
  and 
  is 
  almost 
  sur- 
  

   rounded 
  by 
  patches 
  of 
  a 
  flood 
  of 
  lava, 
  which 
  must 
  once 
  have 
  levelled 
  the 
  whole 
  

   of 
  this 
  mountain 
  basin. 
  The 
  source 
  of 
  this 
  lava 
  is 
  the 
  beautiful 
  volcano 
  of 
  Aysac. 
  

   One 
  of 
  the 
  most 
  picturesque 
  remnants 
  of 
  lava 
  bed 
  is 
  shewn 
  in 
  Plate 
  VI.,

  La 
  Coupe 
  d' 
  Aysac, 
  one 
  of 
  the 
  best-known 
  craters 
  of 
  the 
  Vivarais, 
  is 
  situated 
  

   almost 
  upon 
  a 
  ridge 
  of 
  granite 
  near 
  the 
  head 
  of 
  a 
  small 
  lateral 
  valley 
  connected 
  

   with 
  that 
  of 
  the 
  Volane 
  at 
  Antraigues, 
  and 
  pours 
  its 
  lava 
  first 
  into 
  the 
  small 
  

   valley, 
  and 
  through 
  it 
  into 
  that 
  of 
  the 
  Volane, 
  which 
  has 
  made 
  a 
  remarkable 
  sec- 
  

   tion 
  of 
  it 
  exactly 
  opposite 
  to 
  the 
  village, 
  as 
  accurately 
  figured 
  by 
  Mr 
  Scrope4 
  

   The 
  lower 
  part, 
  which 
  is 
  basaltic, 
  has, 
  as 
  usual, 
  given 
  way, 
  and 
  left 
  a 
  cavern 
  

   beneath 
  the 
  little 
  cascade 
  which 
  descends 
  from 
  the 
  lateral 
  valley.

  is 
  of 
  granite, 
  but 
  covered 
  

   with 
  cinders 
  nearly 
  to 
  its 
  summit. 
  The 
  rocks 
  in

  are 
  of 
  granite, 
  but 
  those 
  between 
  

   the 
  spectator 
  and 
  the 
  cottage 
  in 
  the 
  centre, 
  are 
  of 
  lava, 
  as 
  well 
  as 
  in 
  the 
  lower 
  part 
  of 
  the 
  ravine 
  on 
  

   the 
  right.
