In 1822, another machine was brought before the public, and 

 several of the successful reapers of a later date were modelled 

 after it. Bell, of Scotland, obtained a prize for a reaper, as 

 early as 1829. This machine remained in comparative obscu- 

 rity till the World's Fair, in 1851, when the success of the 

 American machines again stimulated the inventor to come for- 

 ward as a competitor. Previous to 1851, Bell's machine had 

 never been in general use, though used to a limited extent in 

 the neighborhood of the inventor. Its great weight and other 

 defects made it difficult to use for reaping in the field.
