CHAMBERSBURG  HYDRANT  WATER. 
By  Thomas  Canby  Craig,  Ph.G. 
Abstract  from  an  Inaugural  Essay. 
The  town  of  Chambersburg,  Pa.,  is  supplied  with  water  drawn  from 
the  Conococheaque  creek,  the  origin  of  which  is  in  the  South  Moun- 
tain, about  fifteen  miles  to  the  eastward. 
After  skirting  the  base  of  the  mountain  for  some  distance,  this 
stream  changes  its  course  and  flows  through  a  fertile  and  well-culti- 
vated section  of  country,  through  iron,  lime  and  sandstone  land. 
As  no  manufactories  are  situated  along  its  banks  that  would  in  any- 
way unfit  it  for  domestic  use,  it  was  considered  to  be  as  pure  water  as 
was  accessible. 
The  water  is  pumped  directly  from  the  creek — no  dam  or  forebay 
being  used — into  a  reservoir,  and  is  thence  conveyed  to  different  parts 
of  the  town  through  cast-iron  pipes. 
The  specimen  examined  was  collected  on  the  21st  day  of  August — 
a  time  of  year  in  which  farmers  are  hauling  manure  upon  the  fields, 
which,  with  the  old  hay  and  straw  left  from  harvesting  and  dead  weeds 
and  falling  leaves,  forms  decomposing  heaps,  parts  of  which  are  natur- 
ally washed  into  the  creek  by  heavy  rains,  prevalent  at  this  season.
