boiler tubes to the chimney, tlierefore were the steam conducted 

 from the boiler through a tubular heater placed in smoke box, 

 which heater in such well regulated heat would outlast the boiler, 

 while the steam converted to stame without expense, would be 

 so increased in volume and efficiency that two-thirds or more of 

 the fuel and water now consumed in locomotives, would as well 

 serve for their propulsion at present speed, or by suitable arrange- 

 ments be propelled with fewer stoppages and vastly greater speed 

 or power, by the combustion of only their present amount of fuel. 



Ar! desirable will be these improvements, as shameful and 

 foolish will become their neglect, when the importance and 

 great number of engines are recollected, for the saving of which 

 they are susceptible, is immense, and the corresponding credit of 

 eifecting it more immense, and should redound to the honor of 

 this country, as it would do if not hindered by inefficient theo- 

 retical blockheads, and might be returned to England as a small 

 and grateful acknowledgment for the steam engine, spinning 

 jenny and power loom. 



Next, steam coaches, so desirable and often attempted on com- 

 mon roads in England by Gurney, Hancock, Church and others, 

 though unsuccessfully, may now be certain of success, by using 

 stame instead of steam, for if those coaches could run as they did 

 with their limited power, others of a similar construction, deriv- 

 ing four fold power from the same amount of fuel and water 

 could not fail to answer admirably, and the incessant attempts 

 of agriculturists to substitute steam power for horse power would 

 be as wonderfully encouraged and promoted, by finding that 

 steam power may be quadrupled by the same expenditure of 

 fuel and water in high pressure engines supplied with stame. 



Again, if these coaches can travel on common roads, what can 

 hinder such coaches running on plank roads, an 1 successfully 

 competing with locomotives on rails, for running as smoothly on 

 planks, requiring neither turnouts nor switches, so often mis- 

 placed, and misleading to the destruction of engines and life ; 

 which awful contingencies these coaches are free from, and ought 

 to be introduced, and might be, with profit and public advantage, 

 if only limited in size and weight.
