at the Gloucester Meeting, 1853.

upon the particular implements which come before them, than 

 the consulting engineer, who attends the meeting, and whose 

 business is of a more general character, can be expected to do. 

 I shall therefore confine myself to a few general remarks. 



The portable steam-engines exhibited were numerous, and 

 included many good ones in their number. Economy in the 

 fuel required to work them was carried to a greater extent than 

 is consistent with simplicity of arrangement ; indeed the extra- 

 expansion valves, double-action forcing-pumps, and a few other 

 details of that character, which formed a part of the arrange- 

 ments of some of the engines exhibited, are superfluous, and 

 render the implement too complicated for the farmer's purpose. 

 The following table, which marks the progressive improvement 

 in the implement since 1849, will show that the prize implement 

 at Lewes, which had in its construction none of the arrange- 

 ments objected to, approached so near, in consumption of fuel, 

 to the prize engine of this year, exhibited by Clayton, Shuttle- 

 worth, and Co., that the Society ought to discourage the adop- 

 tion of such complications at any of its future meetings.

The fixed engines have not attained that degree of excellence 

 which, it is to be hoped, will be developed ; and, when durability- 

 is taken into consideration, the vertical cylinder will be found 

 preferable to the horizontal one.
