  presence 
  of 
  these 
  terraces 
  indicates 
  that 
  the 
  entire 
  region 
  has 
  

   been 
  slowly 
  elevated. 
  The 
  important 
  gold 
  deposits 
  thus 
  far 
  

   exploited 
  are 
  the 
  gulch 
  and 
  beach 
  placers. 
  Gold 
  is 
  also 
  known 
  

   to 
  occur 
  in 
  the 
  bars 
  of 
  the 
  larger 
  rivers 
  and 
  in 
  the 
  tundra. 
  Prob- 
  

   ably 
  the 
  higher 
  benches 
  and 
  terraces 
  are 
  also 
  worthy 
  of 
  investi- 
  

   gation 
  by 
  the 
  prospectors. 
  

  

  Although 
  the 
  occurrence 
  of 
  gold 
  in 
  sea-shore 
  sands 
  is 
  not 
  pecu- 
  

   liar 
  to 
  this 
  region, 
  still 
  the 
  richness 
  of 
  the 
  Cape 
  Nome 
  beaches 
  is 
  

   very 
  remarkable 
  ; 
  13,000,000 
  is 
  given 
  as 
  the 
  probable 
  gold 
  pro- 
  

   duction 
  for 
  the 
  region 
  for 
  1899.
