to view the demonstration or ride in a small car pulled by the 

 locomotive. 



As on his 1804 locomotive, a single cylinder projecting 

 partly within the end of the boiler was used, but it was verti- 

 cal instead of horizontal. The rear wheels only were driven, 

 actuated by long, return connecting rods attached to the 

 ends of a wide crosshead. Because of the necessary arrange- 

 ment of the cranks on the ends of the rear axle, it was en- 

 tirely possible for the engine to stop on dead center. This was 

 likewise a fault of the 1804 locomotive, which had a single 

 crank. 



The engine is said to have weighed 8 tons and to have 

 traveled at a speed of 12 miles an hour, but troubles with the 

 track ultimately brought the demonstrations to a halt. No 

 dimensions are known today of the original Catch-me-who- 

 can, which has long since disappeared.
