piissed through the bolt-head, with free-bearings in the sides of the bracket 
•JaaX carries the smoke-box ; a slot of 18 inches is cut in the bottom of the 
'bracket ; by turning the crank handle of the screw the bracket with the 
^nsjine resting upon it can be shifted upon the axle plate 9 inches to the 
:ht or left of its usual iiosition. 
Fig. AQ. 
A similar arrangement is adopted to move the hind i^art of the engine, 
which is carried in the usual way by 2 vertical brackets upon the axle of the 
hind wheels. These brackets, instead of being fixed, are made to slide upon 
the axle ; a strong bracket is fixed upon the middle of the axle, and a long 
screw works throuah the head of this bracket, having free bearings in the 
upper parts of the 2 vertical brackets fixed to the engine. By these means 
the engine driver can, without any further assistance, adjust the fly-wheel of 
his engine exactly to th,e line of the driving jralley on the threshing machine 
|or windlass. The cost of applying this improvement to both the axles of an 
'engine is 10?. ; but in practice it may be sufiicient to apply it, at the cost of 
5?. to the fore-axle only. 
Another excellent labour-saving device was exhibited in the light endless 
,rope attached to the handle of the stop-valve of this engine, and carried round 
|two pulleys at the corners of the fire-box to the front of the windlass or other 
machine to be driven. This adaj^tation of reins to the steam horse enables 
the man who is attending to the machine to shut off or let on the steam by 
pulling the right or left hand cord as easily as if his hand were directly in 
contact with the handle. It would be well perhaps if, in other respects, our 
engines and other implements were treated more like horses; were they 
cleaned and tended with the same care that is spent in grooming horses 
their efficiency and longevity would, on some farms, be much increased.
