During  a  war,  supplies  would  be  furnished  from  arsenals  in  the
more  immediate  vicinity  of  the  sea-coast  defences,  viz  :  Frankford
arsenal,  six  miles  above  Philadelphia,  is  of  the  second  class,  and
will  supply  works  on  Delaware  bay  and  river ;  Pikesville  arsenal,
of  the  third  diss,  four  miles  from  Baltimore ;  Washington  araenal
and  Fort  Monroe  arsenal,  both  of  the  first  class,  will  famish  what
may  be  rc({uircd  for  the  sea-coast  defences  of  Chesapeake  bay  and
Potomac  river.  The  last  mentioned  was  established  with  special
reference  to  the  construction  of  the  gun-carriages  required  at  that
post  and  at  Fort  Calhonn.  It  has  been  found  advantageous,  however,
to  construct  there  carriages  for  other  southern  forts ;  hut  it  can-
not be  considered  as  a  permanent  establishment  of  the  first  class,  to
be  kept  up  after  the  occasion  which  called  for  it  sliall  have  passed
by.
The  North  Carolina  arsenal,  at  Fayetteville,  on  Cape  Fear
river,  is  under  construction,  and  was  originally  intended  to  be
made  one  of  the  first  class.  Doubts  have  been  entertained
whether  it  ought  to  exceed  those  of  the  second  class  ;  but  the
plan  is  such  that  it  can  at  any  time  be  extended  according  to  the
original  design.  The  sum  of  eighty  thousand  dollars  will  be  re-
quired to  finish  it  as  one  of  the  second  class S

Cliarleston  depot  is  at  present  of  diminutive  capacity.  It  is
proj>er  to  enlarge  it,  and  thirty  thousand  dollars  will  make  it  use-
ful as  a  place  of  deposit

Auguxta  arsenal,  at  Augusta,  Georgia,  is  of  the  second  class,  and
with  the  two  last  mentioned  will  famish  supplies  required  from
Chesapeake  bay  to  Cape  Florida.
The  Augusta  arsenal  has  its  powder  magazine  detached  and
