The  above  ships,  when  not  making
any  way  through  the  water,  shall
not  carry  the  side  lights,  but  when
making  way  shall  carry  them.
Aet.  6.  A  sailing  ship  under
way,  or  being  towed,  shall  carry
the  same  lights  as  are  provided  by
Article  3  for  a  steam  ship  under
way,  with  the  exception  of  the
white  light,  which  she  shall  never
carry.
Aet.  7.  Whenever,  as  in  the  case
of  small  vessels  during  bad  weather,
the  green  and  red  side  lights  can-
not be  fixed,  these  lights  shall  be
kept  on  deck,  on  their  respective
sides  of  the  vessel,  ready  for  use  :
and  shall,  on  the  approach  of  or  to
other  vessels,  be  exhibited  on  their
respective  sides  in  sufficient  time
to  prevent  collision,  in  such  man-
ner as  to  make  them  most  visible,
and  so  that  the  green  light  shall
not  be  seen  on  the  port  side  nor
the  red  Kght  on  the  starboard  side.
To  make  the  use  of  these  port-
able lights  more  certain  and  easy,
the  lanterns  containing  them  shall
each  be  painted  outside  with  the
colour  of  the  light  they  respec-
tively contain,  and  shall  be  pro-
vided with  proper  screens.
Aet.  8.  A  ship,  whether  a  steam
ship  or  a  sailing  ship,  when  at
anchor,  shall  carry,  where  it  can
best  be  seen,  but  at  a  height  not
exceeding  twenty  feet  above  the
hull,  a  white  light,  in  a  globular
lantern  of  not  less  than  eight  inches
in  diameter,  and  so  constructed  as
to  show  a  clear  uniform  and  un-
broken light  visible  all  round  the
horizon,  at  a  distance  of  at  least
one  mile.
