Could not keep up steam. 
I'o Messrs. IJansome and Sims, of Ipswicli, we awarded the first Prize, the 
consumption of fuel being tlie least, while the arrangement of the engine was 
very simple, and the workmanship very good. 
To Messrs. Barrett, Exall, and Co., of Reading, we awarded the second 
Prize. Although this engine was not quite so low in its consumption of fuel 
as that by Messrs. Clayton and Shuttleworth, yet the price being considerably 
lower, and the arrangement more simple by the absence of a separate expansive 
valve, we considered it more suitable to the objects of the Society. 
We highly commended that by Messrs. Clayton and Shuttleworth, of 
Lincoln ; the consumjition of fuel was very favourable and the workmanship - 
very good. This engine was fitted with separate expansive valve. 
We commended that by Messrs. Tuxford and Son, of Boston, the consump- 
tion of fuel being satisfactory and the workmanship good. 
We have much pleasure in stating that throughout all the engines which, 
were exhibited for trial there was on this occasion much less difference in the 
general points affecting the objects of the Society than on any former occasion. 
We were also glad to find that the absence of the separate and additional 
expansive valve has not been attended with any appreciable disadvantage in 
the economy of the engine, while it has simplified its construction very con- 
siderably ; we are thereby the more strongly induced to suggest for the con- 
sideration of the Society the desirableness that the simjjlicity of the engine 
should form one of the principal tests of merit on future occasions, regard 
being had to the class of persons in whose hands they are placed to work and 
repair.
