ONE OF the most interesting exhibits in the Show-is that staged on Stand No. 46, occupied by J. Fowler arid Co. (Leeds), Ltd. Usually, there is, very little difference in. steam-driv.en vehicles from year to year, but here will be found some new machines of exceptional merit..
Of these, one in particular willcer tainly attract great attention. This is a 10 ton road roller fitted with revolving brush; tar-Spraying device, and trailertype grit or shingle spreader. Thus in one machine are combined practically all the requirements of the road engineer.
The next .machine of interest is a traction engine, which can be converted into a 12 ton road roller.
The giant of the machines is a 16 n.h.p. compound ploughing engine. The popular Tiger tractor is, as Usual., to the fore. This machine is fitted with the patent Dosrim driving wheel, in which two-thirds of the tread are straked steel, and the ether portion is fitted with a. solid rubber tyre in eight removable sections Which can be packed up when worn.
