and 17-inch stroke and two 56y2-inch-dianieter driving 

 wheels at the front. A tubular boiler suggested by Henry 

 Booth, the secretary and treasurer of the Liverpool and 

 Manchester Railway, is said to have contributed greatly to 

 the success of the Rocket during the trials. It must not be for- 

 gotten, however, that in America John Stevens had used 

 successfully a tubular boiler in his experimental locomotive 

 in 1825. 



The Rocket was used on the Liverpool and Manchester 

 Railway until 1836, and from then until 1844 on the Midge- 

 holme Railway near Carlisle. It was presented to the Science 

 Museum in 1862, where it is now an outstanding exhibit in 

 the railroad collection. 



J. G. H. Warren's history of Robert Stephenson & Co., 

 which contains detailed and well illustrated accounts of the 

 Rocket and of the Rainhill Trials, will interest those seeking 

 further details on either subject.

The locomotive Old Ironsides is represented in the Mu- 

 seum's collection by a nonoperable model (figure 64) that, 

 with its tender, is 3 feet long. The model (USNM 180114) 

 was given to the Museum in 1889 by Burnham, Parry, 

 Williams & Co., who were then proprietors of the Baldwin 

 Locomotive Works.
