  log 
  cross-identified 
  perfectly 
  with 
  another 
  found 
  at 
  about 
  the 
  

   same 
  depth 
  a 
  hundred 
  yards 
  away. 
  

  

  These 
  then 
  are 
  the 
  first 
  results 
  of 
  the 
  application 
  of 
  the 
  general 
  

   study 
  of 
  tree 
  rings 
  to 
  archeological 
  work 
  and 
  suggest 
  further 
  pos- 
  

   sibilities. 
  Not 
  only 
  does 
  it 
  seem 
  probable 
  that 
  this 
  beginning 
  of 
  

   relative 
  chronology 
  of 
  the 
  wonderful 
  ruins 
  of 
  the 
  Southwest 
  will 
  

   be 
  extended 
  to 
  include 
  other 
  ruins 
  in 
  this 
  region, 
  but 
  this 
  study 
  of 
  

   the 
  prehistoric 
  writing 
  in 
  trees 
  will 
  help 
  in 
  the 
  clearer 
  understand- 
  

   ing 
  of 
  the 
  climatic 
  conditions 
  which 
  existed 
  in 
  those 
  earlier 
  times 
  

   when 
  the 
  largest 
  bona 
  fide 
  residences 
  in 
  the 
  world 
  were 
  being 
  built, 
  

  

  IX. 
  CONCLUSION. 
  

  

  The 
  economic 
  value 
  of 
  this 
  study 
  of 
  tree 
  rings 
  and 
  climate 
  is 
  to 
  

   be 
  found 
  in 
  the 
  possibility 
  of 
  long-range 
  weather 
  forecasting. 
  In 
  

   noneconomic 
  terms, 
  we 
  are 
  trying 
  to 
  get 
  the 
  interrelationships 
  be- 
  

   tween 
  certain 
  solar 
  and 
  terrestrial 
  activities 
  by 
  the 
  aid 
  of 
  historical 
  

   writing 
  in 
  the 
  trees. 
  The 
  work 
  is 
  not 
  done 
  ; 
  a 
  wide 
  door 
  is 
  open 
  to 
  the 
  

   future. 
  Hence 
  it 
  is 
  impossible 
  to 
  make 
  an 
  artistic 
  conclusion. 
  There 
  

   is 
  no 
  real 
  conclusion 
  yet. 
  Some 
  definite 
  results 
  have 
  been 
  reached 
  

   and 
  they 
  encourage 
  us 
  to 
  hope 
  for 
  larger 
  returns 
  in 
  the 
  future. 
  

   Through 
  this 
  open 
  door 
  we 
  can 
  see 
  attractive 
  objectives 
  looming 
  

   above 
  us 
  and 
  we 
  note 
  the 
  outlines 
  of 
  some 
  of 
  the 
  hills 
  to 
  be 
  sur- 
  

   mounted. 
  To 
  climb 
  these 
  metaphorical 
  hills 
  we 
  need 
  groups 
  of 
  trees 
  

   from 
  all 
  parts 
  of 
  this 
  country, 
  from 
  numerous 
  specially 
  selected 
  

   spots 
  and 
  areas, 
  from 
  distant 
  lands; 
  we 
  need 
  ancient 
  tree 
  records 
  

   from 
  Pueblo 
  ruins 
  and 
  modern 
  Hopi 
  buildings, 
  from 
  mummy 
  case 
  

   and 
  viking 
  ship, 
  from 
  peat 
  bog 
  and 
  brown-coal 
  mine, 
  from 
  asphalt 
  

   bed 
  and 
  lava 
  burial 
  and 
  from 
  all 
  ancient 
  geologic 
  trees 
  in 
  wood 
  and 
  

   stone 
  and 
  coal. 
  We 
  need 
  measuring 
  instruments, 
  workers, 
  museum 
  

   room 
  for 
  filing 
  and 
  displaying 
  specimens. 
  And 
  we 
  need 
  great 
  

   quantities 
  of 
  climatic 
  data 
  obtained 
  with 
  special 
  reference 
  to 
  tree 
  

   comparison. 
  With 
  all 
  this 
  and 
  with 
  a 
  spirit 
  behind 
  it, 
  we 
  shall 
  

   quickly 
  read 
  the 
  story 
  that 
  is 
  in 
  the 
  forest 
  and 
  which 
  is 
  already 
  

   coming 
  to 
  us 
  through 
  the 
  alphabet 
  of 
  living 
  trees.
