  Valley 
  region 
  it 
  is 
  at 
  least 
  partially 
  two 
  brooded; 
  the 
  codling 
  

   moth 
  never 
  has 
  a 
  full 
  second 
  brood, 
  and 
  only 
  in 
  exceptional 
  

   seasons 
  even 
  a 
  partial 
  one. 
  And 
  so 
  there 
  are 
  other 
  points 
  which 
  

   are 
  of 
  economic 
  interest 
  and 
  agricultural 
  importance. 
  

  

  The 
  Dclazvare 
  Valley 
  region 
  extends 
  south 
  from 
  Trenton 
  

   along 
  the 
  Delaware 
  River 
  to 
  the 
  bay, 
  and 
  along 
  the 
  bay 
  to 
  Cape 
  

   May, 
  fringed 
  south 
  of 
  Salem 
  Creek 
  by 
  salt 
  marshes. 
  It 
  extends 
  

   eastward 
  an 
  average 
  distance 
  of 
  about 
  fifteen 
  miles, 
  until 
  about 
  

   opposite 
  Bordentown 
  it 
  crosses 
  the 
  State 
  in 
  a 
  strip 
  about 
  twenty 
  

   miles 
  wide 
  to 
  the 
  Monmouth 
  shore. 
  Its 
  northern 
  border 
  is 
  

   formed 
  by 
  the 
  Piedmont 
  Plain 
  ; 
  its 
  southern 
  and 
  eastern 
  border 
  

   merges 
  into 
  the 
  Pine 
  Barrens. 
  When 
  it 
  reaches 
  the 
  Monmouth 
  

   shore 
  this 
  region 
  sends 
  a 
  narrow 
  strip 
  northward 
  along 
  the 
  coast- 
  

   line, 
  broadening 
  along 
  the 
  shores 
  of 
  Newark 
  Bay 
  so 
  as 
  to 
  take 
  in 
  

   the 
  entire 
  peninsula 
  from 
  Jersey 
  City 
  to 
  Bergen 
  Point 
  and 
  

   extending 
  up 
  the 
  Hackensack 
  Valley, 
  including 
  all 
  the 
  space 
  

   between 
  the 
  Palisade 
  spur 
  of 
  the 
  Highlands 
  on 
  the 
  east 
  and 
  the 
  

   tdgQ 
  of 
  the 
  Piedmont 
  Plain 
  on 
  the 
  west. 
  A 
  southward 
  extension 
  

   of 
  this 
  region 
  extends 
  in 
  a 
  narrow 
  strip 
  along 
  the 
  ocean 
  to 
  

   Point 
  Pleasant 
  and 
  then 
  partially 
  breaks 
  up 
  into 
  a 
  narrow 
  inter- 
  

   rupted 
  fringe 
  between 
  the 
  Pine 
  Barrens 
  and 
  the 
  salt 
  marsh, 
  and 
  

   even 
  appear 
  on 
  the 
  large 
  islands 
  — 
  c. 
  g., 
  near 
  Barnegat 
  City, 
  on 
  

   seven-mile 
  beach, 
  five-mile 
  beach, 
  etc. 
  Islands 
  of 
  this 
  region 
  

   occur 
  also 
  in 
  the 
  Pine 
  Barrens, 
  especially 
  along 
  the 
  edges, 
  and 
  

   the 
  boundaries 
  here 
  are 
  difficult 
  to 
  establish. 
  

  

  This 
  Delaware 
  Valley 
  region 
  contains 
  the 
  best 
  agricultural 
  

   land 
  in 
  the 
  State, 
  and 
  most 
  of 
  it 
  is 
  under 
  cultivation. 
  It 
  is 
  level 
  

   or 
  slightly 
  rolling 
  and 
  has 
  a 
  rich 
  diversified 
  flora 
  and 
  insect 
  

   fauna. 
  Nearly 
  the 
  w'hole 
  region 
  has 
  been 
  thoroughly 
  collected 
  

   over 
  and 
  its 
  peculiarities 
  are 
  well 
  known. 
  

  

  The 
  Pine 
  Barrens 
  occupy 
  the 
  area 
  between 
  the 
  coastal 
  strip 
  

   on 
  the 
  east 
  and 
  the 
  Delaware 
  River 
  region 
  on 
  the 
  w^est, 
  and 
  alto- 
  

   gether 
  contain 
  a 
  greater 
  area 
  than 
  any 
  one 
  other 
  faunal 
  region 
  in 
  

   the 
  State. 
  There 
  are 
  no 
  natural 
  boundaries 
  to 
  the 
  north 
  or 
  west, 
  

   and 
  it 
  simply 
  merges 
  into 
  the 
  Delaware 
  Valley 
  in 
  an 
  irregular 
  

   manner, 
  sending 
  out 
  spurs 
  and 
  islands 
  of 
  all 
  sizes 
  and 
  forms. 
  

   A 
  singular 
  detached 
  island 
  extends 
  along 
  the 
  southern 
  shore 
  of
