These makers have adopted a novelty in the construction of their engine, 

 ■which consists of a casing encircling the lower portion of their boiler, for the 

 purpose of conveying the heated gases from the ends of the small tubes to 

 the smoke-box of the chimney, which is placed at the fire end of the boiler ; 

 the products of combustion are passed by this means through nearly twice the 

 length of the boiler instead of once, according to the practice of most of the 

 other makers ; and as the cylinder is placed in the smoke-box, condensation of 

 steam is prevented thereby : the boiler is supported on improved trusses, 

 inside and outside. The slide of this engine is economically worked by 

 expansion gear, 9 inches out of 12 inches, and further economy is also obtained 

 by an excellent arrangement for heating the vvater previous to its being forced 

 into the boiler. 



No. 2, by the same makers: 4-horse moveable; with plain tubular boiler 

 without water-heating apparatus; of moderate workmanship, and comparatively 

 small heating surface exposed in boiler, which resulted in a small amount of 

 duty done for coal consumed, as shown hy reference to the tabular statement. 



Messrs. Ransomes and Sims : 6-horse moveable. This engine was well 

 made, and the arrangement of its working parts good; the boiler presented a 

 fair amount of surface ; the carriage was well constructed ; and we would 

 notice particularly the turn -plate composed of a spherical and concave surface, 

 brought together so as to maintain the perpendicular of the engine when 

 passing over uneven ground. We consider this an important improvement, 

 in a practical point of view, as preventing any cross strain that might otherwise 

 occur from the irregularities of the road affecting each pair of wheels trans- 

 versely. In this engine steam was taken from the boiler by a slit-pipe 

 passing nearly the whole length inside, within a short space cf the top, and 

 opening into a stop-box, of good construction. This arrangement we con- 

 sidered beneficial, as tending to prevent priming : the duty done was creditable, 

 and we felt pleasure in commending the engine. The 4-horse moveable, by 

 the same parties, is similar to the above, and worked out a corresponding result.
