the proper load for the " Novelty, " no particular 

 experiment was made further than that the 

 engine traversed the line by way of exhibition, 

 occasionally moving at the rate of twenty-four 

 miles an hour. The "Sanspareil, " constructed 

 by Mr. Timothy Hackworth, was next exhibited, 

 but no particular experiment was made with it 

 on this day. This engine differed but little in 

 its construction from the locomotive last sup- 

 plied by the Stephensons to the Stockton and 

 Darlington Railway, of which Mr. Hackworth 

 was the locomotive foreman. 



The contest was postponed until the following 

 day; but, before the judges arrived on the ground, 

 the bellows for creating the blast in the "Nov- 

 elty" gave way, and it was found incapable of 

 going through its performance. A defect was also 

 detected in the boiler of the "Sanspareil," and 

 some further time was allowed to get it repaired. 

 The large number of spectators who had as- 

 sembled to witness the contest were greatly dis- 

 appointed at this postponement; but, to lessen it, 

 Stephenson again brought out the "Rocket," 

 and, attaching it to a coach containing thirty 

 persons, he ran them along the line at a rate of 

 from twenty-four to thirty miles an hour, much 

 to their gratification and amazement. Before 

 separating, the judges ordered the engine to be in 

 1 readiness by eight o'clock on the following morn- 

 ing, to go through its definite trial according to 

 the prescribed conditions.
