inished in this manner has been found. The rig resembles that of some
of Josiah Fox's designs for Jeffersonian gunboats--double-enders
designed to sail in either direction but without the jibs. The topmasts
do not appear to be more than signal poles and apparently were not
fitted with sails; however, some European lateeners did have triangular
topsails over a lateen and it is possible the _Battery_ may have carried
such sails. Considering the stability and displacement of the _Battery_,
the rig is very small and not sufficiently effective. Shrouds were not
required; the masts were supported by runners that were shifted when the
yards were reversed, and in tacking. Apparently the jibstays also could
be slacked off so that the lateen yards would not have to be dipped
under them.

The inboard profile is on tracing paper and the notes are in French.
This drawing is of a simplified hull form having flat-bottom hulls with
chines. It is possible that this is a tracing of a preliminary drawing
obtained by Marestier or Montgery, but no documentation can be found.
Its importance is that it shows in some detail the engine and boilers,
as well as the wheelbox, and another drawing of the paddle wheel, more
or less duplicating the wheel shown in the Danish plan. No details of
the deck arrangements are shown in any of the plans, except for the dome
skylight over the fireroom in the boiler hull.

Both the lines plan and the inboard drawing show construction
midsections and hull connections. These plans show that the engine was
not inclined, but rather was vertical, contrary to Fulton's patent
drawing. The piston rod and the crosshead obviously passed through its
gun deck in a large hatch. Also it is plain that there must have been
large hatches afore and abaft the wheelbox to make the stepped wheelbox
construction desirable. There also must have been a hatch in the gun
deck under the domed skylight. It is improbable that the engine and
skylight hatches were used for ladderways, passing scuttles, or
companionways.

The boilers are shown in the inboard profile about as described and
drawn by Marestier but with two stacks on each boiler, one to each flue;
Marestier's sketch in his report on American steamships shows the flues
of each boiler trunked into a single stack. The battery had two boilers
and
