A short treatise on the application of steam [microform] : whereby is clearly shewn, from actual experiments, that steam may be applied to propel boats or vessels of any burthen, against rapid currents, with great velocity. : The same principles are also introduced with effect, by a machine of a simple and cheap construction, for the purpose of raising water, sufficient for the working of grist-mills, saw-mills, &c. and for watering meadows and other purposes of agriculture. / By James Rumsey, of Berkeley County, Virigina.
