STADIA  HAND  LEVEL 
(TELESCOPIC) 
The  Stadia  Hand  Level  has  an  erecting  10-inch  telescope  with  1-inch 
objective.  The  objective  is  drawn  out  for  focusing  and  the  eyepiece  is 
adjustable  for  defining  the  stadia  hairs,  which  read  1  :  100.  This  instru- 
ment will  be  found  very  useful  for  preliminary  surveys,  cross  sectioning, 
railroad  construction  work,  exploration  of  streams  for  water  power,  etc. 
When  set  on  a  staff  or  tripod,  a  fairly  accurate  line  of  levels  can  be  run. 
It  is  easily  carried,  as  it  weighs  scant  H  pounds.  In  connection  with  a 
flexible  leveling  rod  it  constitutes  an  ideal  outfit  for  preliminary  work,  on 
account  of  its  light  weight  and  easy  manipulation.
