The Robert Fulton has a much more compact appearance, and 

 weighs twelve thousand seven hundred and forty two pounds, of 

 which eight thousand seven hundred and forty five pounds, rest on 

 one pair of wheels. It was made as we have said, by Robert Ste- 

 phenson, the celebrated English Engineer of New Castle uponTyne. 

 The frame is as long as that of the DeWitt Clinton, and is mounted 

 on wooden wheels, strongly bound with iron. There are two cylin- 

 ders each of ten inches diameter, and fourteen inches stroke ; these 

 are in the lower part of the chimney, and are kept warm by the 

 smoke and hot air. The pistons are connected with the axis of the 

 hind wheels. The fire is made in a cylindrical furnace, hanging 

 down between them, and the heat passes directly through eight rows of 

 horizontal tubes of the length of the boiler. The steam pipes pass 

 through the boiler just above the tubes, and by a simple contrivance, 

 the steam ascends to the top of a steam chamber, and there enters a 

 funnel-mouthed tube, connected with the steam pipes. Any bad ef- 

 fects of the surging of the water are of course prevented. The 

 safety valve is of the ordinary kind. 



The eduction pipes, are carried partly up the chimney, and pow- 

 erfully assist the draft. It has been tried and found to succeed ad- 

 mirably. Its great weight renders its usefulness somewhat problem- 

 atical upon a wooden rail. There are yet some accurate experi- 

 ments to be made on these subjects, and therefore we shall dismiss 

 this part of our subject with a quotation from the original description 

 of this engine, now before us in the hand writing of Mr. Stephenson. 

 " As to the power of this engine, it would take twenty tons without 

 difficulty, but with twelve it will be much better. The small incli- 

 nation of one in two hundred and twenty five, will affect the motion 

 of the engine very little." 



Some experiments will shortly be made in relation to friction and 

 velocity on this road, by some gendemen connected with the Albany 

 Institute, in connection with the Engineer, which will probably throw 

 some light upon this fruitful subject of calculadon. 



The stock of this company has stood deservedly high in the mar- 

 ket, and will undoubtedly produce to its proprietors, large and in- 

 creasing dividends.
