Three portable steam-engines, manufactured by Messrs. vibram five fingers Clayton, Shuttleworth, and Co., the powers of 5, 7, and 9 horses respectively. Two of these engines were of the same construction, the third a two-cylinder vibram fivefingers engine, which we think an unnecessary complication when designed for agricultural purposes. The three boilers were all tubular, and precisely the same in make, thereby obtaining on the trial an unfair advantage over but one of a kind exhibited by other parties. In saying this, we intend not the slightest reflection upon Messrs. Clayton, Shuttleworth, and Co., but under Mbt shoes clearance similar circumstances we should recommend in future that but one of a kind should be tested for each exhibitor. The workmanship of these engines was vibram five fingers kso good, the arrangement for working the governors new, and the general performance satisfactory, doing good duty for the fuel consumed, as will be seen by reference to vibram five fingers sale the tabular statement.The crank-shaft we thought too short between the bearings to remain steady in constant wear ; the piston and valve-rods worked through screw stuffing-boxes, which is a method now seldom adopted but for the sake of cheapness : five fingers shoes the engines were mounted on iron wheels, which we think not so suitable for farm roads aswooden ones. Having made these observations, we have now the pleasure to add that we felt so well satisfied with the quick generation of steam and duty done by these engines, as to select the 7-horse article, No. 2, for the second prize of twenty-five pounds."" A 6-horse portable engine, also manufactured by Messrs. Garrett and Son. The general remarks made upon their former engine are also equally applicable to this as respects workmanship and strength; it is also fitted with the necessary steam and water-gauges and governors, and we would especially notice the strength and construction of the one carriage of the four bearings of the crank shaft, admitting vibram five fingers shoes of their being bored out at one operation in the lathe. The boiler of this engine is tubular, but the fire-box circular, the outer case being an uniform cylinder throughout, thereby attaining great strength and durability, points so essential to be noticed in engines to be worked by unexperienced hands ; the plates of this boiler were $, and tubeplate |-inch thick, showing much greater strength than in the one which obtained the second prize. The duty performed by this engine was very satisfactory, as will be seen by refereuce to the tabular statement: and if we make due allowance for a cold rain falling during the whole of this trial, the other engines having the advantage of a hot sun, the result will assign to this engine in duty done, as well as in strength and mbt sandals durability, the first prize of fifty pounds, which was awarded accordingly.
