  wells 
  have 
  been 
  bored, 
  all 
  of 
  which 
  are 
  now 
  flowing. 
  These 
  wells 
  supply 
  suGB- 
  

   cient 
  water 
  for 
  the 
  use 
  of 
  the 
  thirty 
  four 
  families 
  comprising 
  the 
  settlement, 
  

   and 
  for 
  the 
  irrigation 
  of 
  their 
  land, 
  which, 
  previously 
  of 
  little 
  value, 
  has 
  now 
  

   considerably 
  enhanced 
  in 
  price.

  these 
  wells
