  growing 
  upon 
  it 
  extend, 
  their 
  roots 
  very 
  far 
  horizontally, 
  while 
  they 
  

   penetrate 
  but 
  a 
  short 
  distance 
  below 
  the 
  surface. 
  They 
  are 
  therefore 
  

   readily 
  uprooted, 
  and 
  in 
  the 
  overthrow 
  carry 
  a 
  considerable 
  extent 
  of 
  

   soil 
  with 
  them. 
  

  

  If 
  the 
  forces 
  acting 
  during 
  the 
  whole 
  period 
  that 
  the 
  trees 
  were 
  

   within 
  the 
  sphere 
  of 
  action 
  of 
  the 
  storm, 
  be 
  supposed 
  of 
  equal 
  intensity 
  

   but 
  varying 
  direction, 
  then 
  the 
  trees 
  extending 
  their 
  roots 
  unequally 
  in 
  

   different 
  directions, 
  will 
  oppose 
  unequal 
  resistances 
  in 
  those 
  directions, 
  

   and 
  two 
  trees 
  side 
  by 
  side 
  may 
  be 
  thrown 
  different 
  ways. 
  Several 
  trees 
  

   presenting 
  thus 
  a 
  want 
  of 
  conformity 
  of 
  direction, 
  would 
  induce, 
  at 
  first 
  

   view 
  the 
  idea 
  of 
  a 
  total 
  want 
  of 
  regularity 
  calculated 
  to 
  baffle 
  observation. 
  

   If 
  the 
  forces 
  vary 
  in 
  intensity 
  as 
  well 
  as 
  in 
  direction, 
  this 
  difficulty 
  will 
  

   be 
  increased. 
  Again, 
  the 
  circumstances 
  of 
  the 
  proximity 
  of 
  other 
  

   trees 
  may 
  not 
  only 
  influence 
  the 
  direction 
  in 
  which 
  a 
  tree 
  will 
  fall, 
  

   after 
  its 
  motion 
  has 
  commenced, 
  but 
  the 
  very 
  direction 
  in 
  which 
  the 
  

   force 
  producing 
  its 
  fall 
  may 
  act. 
  And 
  these 
  remarks 
  apply 
  in 
  even 
  

   greater 
  force 
  to 
  the 
  case 
  in 
  which 
  trees 
  are 
  broken, 
  instead 
  of 
  being 
  

   overthrown. 
  

  

  The 
  unequal 
  strength 
  of 
  parts 
  of 
  a 
  building, 
  and 
  its 
  protection 
  by 
  

   adjacent 
  buildings 
  must 
  produce 
  difficulties 
  of 
  a 
  similar 
  kind; 
  while 
  

   in 
  the 
  trees 
  near 
  to 
  houses 
  we 
  should 
  look 
  for 
  even 
  more 
  irregularities 
  

   of 
  direction, 
  than 
  in 
  those 
  in 
  an 
  open 
  wood. 
  

  

  These 
  remarks, 
  it 
  will 
  be 
  seen, 
  are 
  not 
  intended 
  to 
  set 
  aside 
  any 
  

   cases 
  which 
  may 
  appear 
  inapplicable 
  to 
  a 
  general 
  conclusion, 
  but 
  

   merely 
  to 
  guard 
  against 
  unreasonable 
  requirements. 
  

  

  Of 
  the 
  diagrams, 
  figures 
  1, 
  4, 
  5 
  and 
  7, 
  are 
  drawn 
  to 
  the 
  same 
  scale; 
  

   the 
  scales 
  of 
  figures 
  3 
  and 
  6 
  are 
  attached 
  to 
  them 
  respectively; 
  and 
  

   figure 
  2 
  is 
  not 
  drawn 
  to 
  a 
  scale. 
  

  

  The 
  directions 
  of 
  the 
  trunks 
  of 
  the 
  trees 
  are 
  represented 
  in 
  all 
  but 
  

   figure 
  1 
  by 
  arrows. 
  In 
  order 
  to 
  make 
  these 
  directions 
  appear 
  distinctly, 
  

   these 
  arrows 
  are 
  out 
  of 
  proportion 
  to 
  the 
  horizontal 
  distances 
  between 
  

   the 
  trees. 
  This 
  causes 
  the 
  tops 
  of 
  trees 
  to 
  appear 
  very 
  near, 
  which, 
  

   in 
  many 
  cases, 
  were 
  not 
  so. 
  

  

  The 
  first 
  point 
  to 
  which 
  we 
  traced 
  the 
  action 
  of 
  the 
  storm, 
  was 
  

   near 
  the 
  farm 
  of 
  Mr 
  M. 
  S. 
  Garretson, 
  about 
  seven 
  miles, 
  a 
  little 
  south 
  

   of 
  west, 
  from 
  New 
  Brunswick. 
  It 
  crossed 
  the 
  Millstone 
  river, 
  and 
  the
