on the crank-shaft engages with the pinion on the sleeve, and 
the other pinion on the right-hand side engages the right-hand 
pinion on the counter-shatt. The counter-shaft carries a pinion 
on its right-hand side, and outside the frame, which gears into 
the open wheel on the main axle of the road-wheels, which also 
carries the differential gear. On the main axle on the left-hand 
side, and inside the driving-wheel, is a drum with 100 yards of 
wire rope coiled in it, which can be used for hauling purposes 
in case the engine gets into difficulties. When the lever handle 
is placed in the middle position all the wheels are disengaged. 
This is a simple and excellent arrangement and a decided im- 
provement. The pinions a, a, c, and d, are shrouded, which 
greatly increases their strength. It should also be noticed that 
the intermediate shaft, being stationary, acts as a brace to the 
brackets. The price of the engine is 510/. 
Messrs. John Fowler and Co., not to be behind their enter- 
prising competitors, exhibited two Traction Engines with com- 
mendable improvements. The first of these to be noticed 
is No. 8^ in the Catalogue, which was not very accurately 
described as a 6-horse power large wheeled traction engine, 
adapted only for traction purposes, having no JIij-icJiccl, inasmuch 
as the engine which the Judges examined had a fly-wheel. Mr. 
Anderson has furnished me with the following description, which^ 
with the assistance of the illustration, will, I liope, be understood.
