_Nicholas J. Roosevelt, of the State of New Jersey, Esqr. sends
greeting_:

propelling of boats or vessels through water by the force & agency of
fire & steam, the construction of which discovery, invention &
improvement is specified as follows, as the mode to which I have given

_THE SCHEDULE referred to in these Letters potent and making part of the
same containing a description in the words of the said Nicholas J.
Roosevelt himself of his improvement in propelling Boats, &c. by
steam._
In a boat or vessel of any form, but of sufficient capacity to contain
the machinery required, I place a Steam Engine of a power proportioned
to the restance to be overcome, in propelling a boat or vessel a given
distance in a given time, this steam Engine is supplied by a boiler of
the usual form or made Cylindric one or more at pleasure so as to be
of sufficient capacity to feed the Engine. I next place two wheels
over the sides, on the axis of which I put flyes, dispence with them
or otherwise combine them at pleasure, either to regulate motion or
give additional velocity, or they may be connected with the water
shaft and steam Engine, by wheels so as to give any number of
revolutions that may be desired. The arms of the water wheels I would
make of wood, to which I attach floats or paddles of cast Iron, or of
Boiler plate thick sheet Iron, though they may be made of wood. These
floats I make move up and down on the arms, by means of screws and
holes, so as to make them enter deeper or shallower in the water, in
taking a purchase or hold on the water agreeably to the depth of water
the boat may draw, and the lading there may be on board, or agreeably
to other circumstances. The supporters of the outer ends of the water
wheels shaft to be made of Iron with braces, though if required they
may be made of wood.

Of the foregoing correspondence, but a small portion relates to the
question of wheels over the sides. It is inserted at length
however,—going, as it does, to shew the warm interest, and the active
measures that were on foot at the close of the eighteenth century to
develope one of the mighty agencies of the nineteenth. The crudeness of
many of the suggestions and the literary carelessness of the
correspondence on both sides, is indicative of a very different
condition of things from that which exists at present.
