  NOTES 
  AND 
  DIAGRAMS 
  ILLUSTRATIVE 
  OF 
  

  

  Trenton 
  and 
  Brunswick 
  canal, 
  about 
  half 
  a 
  mile 
  to 
  the 
  west 
  of 
  Mr 
  

   Garretson's 
  dwelling, 
  and 
  its 
  track 
  was 
  between 
  this 
  house 
  and 
  

   a 
  barn 
  about 
  sixty 
  yards 
  from 
  it. 
  A 
  small 
  portion 
  of 
  a 
  light 
  

   fence 
  and 
  some 
  other 
  matters 
  were 
  carried 
  across 
  the 
  road 
  upon 
  

   which 
  the 
  house 
  fronts, 
  and 
  a 
  part 
  of 
  the 
  trees 
  in 
  an 
  orchard 
  thrown 
  down. 
  

   Neither 
  the 
  barn 
  nor 
  dwellinghouse 
  was 
  injured, 
  and 
  the 
  action 
  was 
  

   described 
  as 
  that 
  of 
  a 
  strong 
  wind 
  of 
  limited 
  breadth. 
  In 
  the 
  orchard 
  

   the 
  trees 
  to 
  the 
  south 
  of 
  the 
  path 
  of 
  the 
  storm 
  were 
  thrown 
  northwardly 
  

   and 
  those 
  to 
  the 
  north 
  southwardly. 
  Passing 
  on 
  to 
  the 
  east, 
  the 
  next 
  effect 
  

   was 
  seen 
  in 
  overthrowing 
  a 
  large 
  cherry 
  tree, 
  and 
  carrying 
  off 
  the 
  south- 
  

   west 
  corner 
  of 
  the 
  thatched 
  roof 
  of 
  a 
  small 
  saw-mill. 
  The 
  most 
  violent 
  

   action, 
  however, 
  at 
  this 
  place 
  was 
  upon 
  a 
  wood 
  nearly 
  east 
  from 
  the 
  dwell- 
  

   inghouse, 
  and 
  is 
  shown 
  in 
  the 
  sketch 
  figure 
  1 
  , 
  Plate 
  XXIII. 
  This 
  is, 
  per- 
  

   haps, 
  the 
  most 
  hasty 
  of 
  all 
  the 
  determinations 
  which 
  I 
  made, 
  as 
  the 
  interest 
  

   which 
  attached 
  to 
  the 
  effects 
  wanted 
  the 
  force 
  of 
  novelty 
  : 
  they 
  being 
  simi- 
  

   lar 
  to 
  those 
  referred 
  to, 
  as 
  observed 
  by 
  professors 
  Henry 
  and 
  Johnson. 
  The 
  

   ground 
  represented 
  in 
  the 
  diagram 
  is 
  irregular, 
  consisting 
  of 
  a 
  hill, 
  the 
  

   sides 
  of 
  which 
  are 
  covered 
  by 
  wood 
  ; 
  the 
  hill 
  being 
  cut 
  by 
  a 
  ravine 
  which 
  

   was 
  apparently 
  near 
  the 
  northern 
  border 
  of 
  the 
  storm, 
  or 
  of 
  that 
  part 
  in 
  

   which 
  the 
  trees 
  were 
  thrown 
  in 
  the 
  direction 
  of 
  its 
  course. 
  The 
  wood 
  was 
  

   of 
  young 
  hickory 
  and 
  black 
  oaks 
  without 
  undergrowth, 
  but 
  even 
  here 
  

   some 
  irregularities 
  were 
  seen. 
  The 
  spiral 
  growth 
  of 
  a 
  few 
  of 
  the 
  

   trees 
  had 
  led 
  the 
  proprietor 
  of 
  the 
  farm 
  to 
  think, 
  and 
  speak, 
  of 
  the 
  

   whole 
  effects 
  as 
  produced 
  by 
  a 
  whirlwind. 
  He 
  pointed 
  out 
  those 
  

   cases, 
  which 
  were, 
  obviously, 
  seen 
  to 
  have 
  resulted 
  from 
  the 
  cause 
  which 
  

   I 
  have 
  just 
  assigned. 
  It 
  will 
  be 
  observed 
  in 
  the 
  figure 
  that 
  of 
  nine 
  

   trees 
  there 
  represented, 
  the 
  two 
  on 
  the 
  north 
  side 
  of 
  the 
  storm 
  fell 
  

   southward 
  and 
  eastward, 
  one, 
  g, 
  points 
  out 
  its 
  direction 
  nearly, 
  and 
  

   five 
  of 
  the 
  six 
  of 
  the 
  south 
  side 
  are 
  directed 
  between 
  N. 
  10° 
  E., 
  and 
  

   E. 
  40° 
  N. 
  The 
  breadth 
  of 
  the 
  storm 
  was 
  here 
  about 
  200 
  yards, 
  and 
  

   its 
  direction 
  about 
  that 
  of 
  the 
  line 
  A 
  B. 
  

  

  We 
  next 
  repaired 
  to 
  a 
  point 
  where 
  the 
  destruction 
  was 
  reported 
  to 
  

   have 
  been 
  considerable, 
  namely, 
  to 
  the 
  farm 
  of 
  Mr 
  D. 
  Polhemus, 
  be- 
  

   tween 
  two 
  and 
  three 
  miles 
  E. 
  17° 
  N. 
  from 
  Mr 
  Garretson's. 
  Here 
  a 
  

   very 
  curious 
  fact 
  was 
  developed, 
  which 
  I 
  have 
  attempted 
  to 
  represent 
  

   in 
  the 
  sketch 
  and 
  ground 
  plan
