270 THE " SANSPAREIL." CHAP. XIII. 



engine, so that there was nothing for the " Rocket " but 

 the practical test. The first trip which it made was 

 quite successful. It ran about twelve miles, without 

 interruption, in about fifty-three minutes. 



The " Novelty " was next called out. It was a light 

 engine, very compact in appearance, carrying the water 

 and fuel upon the same wheels as the engine. The 



; weight of the whole was only three tons and one hun- 

 dredweight. A peculiarity of this engine was that the 



j air was driven or forced through the fire by means of 

 bellows. The day being now far advanced, and some 

 dispute having arisen as to the method of assigning 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 Hack- 

 worth, 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 supplied 

 by George Stephenson to the Stockton and Darlington 

 Railway, of which Hackworth was the locomotive 

 foreman. It had the double tube containing the fire 

 passing along the inside of the boiler, and returning 

 back to the same end at which it entered. It had also 

 the steam-blast in the chimney ; but the contraction 

 of the orifice by which the steam was thrown into the 

 chimney, for the purpose of intensifying the draught, 

 being a favourite idea of Mr. Hackworth (though of this 

 Mr. Goldsworthy Grurney claims the credit), he had 

 sharpened the blast of his engine in a remarkable 

 degree ; and this was perhaps the only noticeable feature 

 in the " Sanspareil." 



The contest was postponed until the following day ; 

 but before the judges arrived on the ground, the bellows 

 for creating the blast in the " Novelty " gave way, and 

 it was found incapable of going through its performance.
