;i,ttacbed on one side of tlio boiler, with the crank shaft 

 mounted upon a steam chest ; and all the working; parts 

 are boxed under cover, but easy of access. No less 

 than three! three-horse and four two-horse portable en- 

 gines were exhibited by this maker. 



Ransomes and 8ims showed a twelve-horse engine, 

 fitted with reversing gear, as well as ten-horse, eight- 

 horse, and seven-horse engines, having their simple and 

 admirable locking gear. 



llobey and Co.'s engine has a three-inch water-space 

 underneath the ash-pan, a very safe arrangement, and 

 allowing the sediment to be blown out of the boiler by a 

 cock for the purj)ose. 



Smith and Ashby's two-and-a-half-horse power porta- 

 bles are exceedingly neat, simple, and well made, with flue 

 and tube boilers. Price only £70. They will do the 

 work of three horses, and are so compact as to pass 

 through a f lur-feet doorway. 



Barrett, Exall, and Andrewes have also a two-horse 

 power portable engine, made to drive a small combined 

 thrashing machine. 



Cambridge's two-and-a-half horse engine is made with 

 a vertical cylinder. Price £80. 



Bach showed an engine having the singular arrange- 

 ment of the pump being worked by a prolongation of 

 the piston-rod acting as a plunger. 



Ilornsby and Sons' engines are so well known, that 

 we can only express our admiration of their per- 

 fect workmanship. The twelve-horse engine has re- 

 versing gear, constituting a form of engine likely 

 to be used very extensively, now that steam cul 

 ture is becoming practically available. Clayton and 

 Shuttleworth's exhibition of portable and fixed en- 

 gines of different powers was an extraordinary spec- 

 tacle of first-class work, including their well-known 

 patent engine, with steam jacketed cylinder in the smoke 

 box. Nicholson's 2|-horse power portable is an ad- 

 mirable little engine, price only £70, doing all the hard 

 work connected with stall-feeding, and capable of driving 

 a small thrashing-machine. Hart, Gibbous, and Co. 

 exhibited a 3|-horse portable engine ; Wheeler and Co. 

 a 3-horse power portable; Maggs and Co. a 2j-horse 

 power portable engine ; and Bentall and also Turner 

 2-horse power portables ; these, indeed, forming one of 

 the most noticeable features in the stands. Ruston, 

 Proctor, and Co's. 8-hors8 engine, with reversing mo- 

 tion, is very simple in arrangement and good con- 

 struction. Tuxford and Sons' engines, with vertical 

 cylinder, inclosed in a house, and either with tubular 

 or flue and tube boilers, are too well known to need 

 further notice here ; this year, they have also produced 

 a horizontal-cylinder engine (with cylinder in a steam- 

 jacket above the fire-box), for supplying customers at a 

 somewhat lower figure. Williamson and also Wood 

 and Sons showed 3-horse power portable engines. 

 In Maggs' 2-borse engines the piston-rod works in the 

 pump-barrel instead of guides. 



In addition to the massive traction-engines of Burrell 

 and of Tuxford and Sons, fitted with the endless-rail- 

 way, there are other engines, constructed for travelling 

 along common roads. Burrell's application of the 

 endless-rails to ordinary thrashing-engines, so that the 

 engine^ipropels itself, while a horse in a pair of shafts 

 steers it, is familiar to our readers. Garrett and Sons 

 have a double-cylinder 12-horse engine, which drives 

 one of its travelling-wheels by toothed gearing, and is 

 steered by a horse in shafts : it is also fitted with the 

 indispensable accessary of a break. Clayton and Shuttle- 

 worth showed a 7-horse single-cylinder engine, fitted 

 with reversing motion, and toothed wheels for driving 

 the travelling wheels, the steerage being very readily 

 effected by a wheel on a transom in front. The price, 

 ^350, must be rather a high figure. 



CHAFF-CUTTERS, CAKE.BREAKERS,TURNIP- 

 CUTTERS, &c. 



A considerable number of cutters were tested, the 

 length of the cut being ascertained by putting strips of 

 cardboard, about an inch and a half wide and a couple 

 of feet long, amongst the hay or straw, as the stuff often 

 comes obliquely to the front, and makes chaft' longer 

 than the §ths of an inch specified. After the prelimin- 

 ary trials, the several chosen machines were worked 

 for five minutes each, the power being taken by the 

 dynamometer invented for the purpose. Richmond and 

 Chandler's, with 18,500 revolutions, cut 24Mbs. of 

 chaft"; Turner's, in 20,050 revolutions, cut 2241bs. of 

 chaff; Smith and Ashby's, in 19,800 revolutions, cut 

 20Jlbs. of chaff; Page and Co.'s, with 18,575 revolu- 

 tions, cut 24.^1bs. of chaff; Mallard's, in 18,420 revo- 

 lutions, cut 151bs. of chaff; Hill and Smith's, with 

 20,410 revolutions, cut 231bs. of chaff; Barrett and 

 Exall's, in 16,100 revolutions, cut lOJlbs. of chaff. 



Each of the oilcake breakers worked by steam, power 

 was required to break three different sizes of cake, three 

 minutes being allowed for the breaking of the first size, 

 two minutes for the second, and one minute for the 

 third size. The results were as follows :

The time allowed for working each root-cutter or 

 pulper was, in some cases, three minutes, in others two 

 minutes, according to the size or description of the im- 

 plement. The results are :
