Fulton’s correspondence that Imperial permission for this was obtained.
Fulton, however, died in the year 1815, and at the time of his death
the steamboat _The Emperor of Russia_ was in course of construction
previous to being transferred to Russian waters. This enterprise was
postponed and subsequently taken up by other contractors. But the
same year (1815) we find Charles Baird engaged in doing what Fulton
would have carried out had he lived. The upper illustration, then,
which faces page 84 represents a drawing of the steamboat _Elizabeth_.
Originally a barge, she was rebuilt and engined by Baird in 1815 at
St. Petersburg for service on the Neva. The steering arrangement
is not dissimilar to that of some of the Thames sailing barges of
to-day, with the use of the tackle leading from the rudder through the
ship’s quarter to the helm. The reader will doubtless be not a little
amused to notice the brick chimney which stands up in the boat as if
rising from a factory. The engine is hidden away underneath the deck,
but it was of the side-lever type, of which we have already spoken,
with a single cylinder and air-pump. The boiler will be seen placed
aft. The weight of the paddle-wheels was partly supported by the
rectangular frame-work which will be seen stretched across the hull.
The paddle-wheels had each four floats, which were kept level by means
of bevel gear. The other illustration facing page 84 shows another
steamer, which Baird built two years later for passenger traffic
between St. Petersburg and Cronstadt. It will be noticed that, as in
all these early steamboats, the paddle-wheels were placed far forward
towards the bows. In this ship both paddle-wheels were fitted with six
floats, which were driven at fifty revolutions per minute by means of
a side-lever engine that had a large fly-wheel. The arrangement of
this ship’s engines was similar rather to those of the _Comet_ than of
the _Clermont_. Looking at the lower drawing in this illustration we
can easily see how she was propelled. Amidships is the boiler, from
which steam is conveyed to the cylinder, through which appears the
piston-rod, which in turn connects with the side-lever, that is placed
as low as it can be in the boat. The connecting rod comes up from the
forward end of the side-lever to the crank, which is attached to the
shaft, and the latter, revolving, of course turns the paddle-wheels.
