We would observe in addition, that the driving-wheel of this vibram five fingers engine contains a groove for a round band, which cannot be too highly recommended for working threshing-machines, as avoiding the great exactness necessary in placing the machines when working with a flat belt." Page 161.—Stand 83, art. 1. " vibram fivefingers A 6-horse portable engine, manufactured by Messrs. J. and E. Headley. This engine was made with a double cylinder, and had a tube-boiler, workmanship good, but working parts too slight for the power stated; the throttle-valve was placed in the smoke-box, an arrangement which we think bad and inconvenient; 107 minutes were occupied in raising the steam to 45 lbs. Mbt shoes clearance pressure, and the duty performed was comparatively small ; the result would have been something better had the firing been properly attended to. The exhibitor stated that his engine was better suited to work with coke than coal."Tlireshing-Machines.*—Great vibram five fingers kso pains were taken with the trial of these machines, as it was felt that their importance could hardly be overrated, and yet that no trial of them had hitherto been made which could be considered really satisfactory. A great step in advance was undoubtedly made at v vibram five fingers saleYork, where for the first time the power required to work each machine was ascertained ; but even this important step fell short of the real requirements of the case, five fingers shoes as the mode of registering the power was by no means perfect, and the method then adopted was also deficient, from its furnishing no means of judging of the efficiency of the horse-works. A large majority of threshingmachines are necessarily worked by horse-power, so that no statement of their relative merits could be generally satisfactory which left the horse-works unnoticed. The importance of this point will appear when the tabular statement (A) comes under consideration. vibram five fingers shoes The trial commenced by a general examination of each machine by the judges and consulting engineer, after which a single horse (and in some instances a second) was attached, with a dynamometer, and the empty machine driven at such a rate as, according to the maker's description, would cause the drum to revolve at the requisite speed. After trying a few of the machines it became evident that the specifications furnished by the makers were not accurate, and it was found necessary to count the cogs of all the working parts and calculate the number of seconds in which the horse-wheel should revolve in order to produce the number of revolutions of the drum intended by the exhibitor. It is much to be wished that exhibitors would be strictly accurate in describing their machines, as misstatements not only lead to great waste of time and trouble in conducting the trials, but frequently place a machine in an unfavourable position as mbt sandals respects other
