ng rules given by M'Kay[23] in 1839. The fore
spencer gaff, used as a crane for handling coal and cargo if the fore
or main yards were not available, may have been long enough to be used
also as a crane to handle the side wheels. The stack and mainstays may
have made the fore spencer sail a nuisance, so it may not have been
set while the vessel had her engine. In general, aside from the use of
the spencers on fore and main, the sail plan shown is of standard
proportions and arrangement of 1815-1825. For rigging, Darcy Lever's
book[24] was consulted. The drawing of the reconstructed _Savannah's_
sail plan agrees with contemporary sail plans of ships in the author's
collection. The log shows she set studding sails and had all the light
canvas of a ship of her type.

There remain a number of matters that do not directly concern the
reconstruction project but which are of sufficient technical
importance to warrant comment. Apparently the engine was mounted on a
wooden frame consisting of two large oak timbers on each side, say
about 10" x 10", one above the other, that probably supported iron
saddles in which the two cylinders rested. Between each pair would
have been the iron track, or channel, in which the ends of the
crosshead travelled, along the axis of the engine in elevation. These
frames measured about 9 feet 2 inches, outside to outside, and reached
from the beams of the upper deck on either side of the crank hatchway
to abaft the mainmast on the lower deck. It is probable that the fore
and after ends of the frame were supported by stanchions stepped on
the lower deck at the fore end and in the hold at the after end. The
crosshead was of iron and probably had shoes at the ends to work in
the tracks or channels in the frame. To help steady the crosshead,
these shoes probably were a foot or more long, for the loading of the
crosshead is spread out. The pitman to the paddle wheel shaft is to
starboard of the centerline of the engine; the steam cylinder piston
is slightly off center of the frame and crosshead; and the piston of
the air cylinder is close to the port engine frame. The steam lines to
the valves of the steam cylinder come in horizontally over the frames.
As has been mentioned, the frame may also have supported the paddle
wheel axle bearings at the crank.

This engine has been criticized by some writers (see Tyler's[25]
resume of Gilfillan's[26] comments), but the _Savannah_ logbook shows
it gave no troub
