The rubber tyro industry of Britain has a capital of between £25,000,000 and £30,000,000, and in normal times employed 65,003 men. At present tyre works have little to do, owing to foreign importations, of which there were last year something like 1,100,000.

The correct proportion of petrol for a perfect fuel mixture is .07 of a pound of gas to a, pound of dry air. It is_ possible to operate on a mixture oontaining as much as .12 of a pound of gas to the pound of dry air, which is nearly twice aa much petrol ao is needed. This >wide range of mixture strength constitute!, the greatest factor in wastage of petrol. The majority of car owners run more nearly at the maximum strength than at the minimum, which would give them butter results. They are using nearly twici as much fuel as there is any need for.

An instance of the excellent laboursaving equipment now being used in the building and rebuilding of English roadsi is instanced in a hug© concrete-road breaker, which powerful machine, weighing 20 tons, travels over concrete roads and pounds them to pieces, in order, that a new road surface may be laid. This machine is provided with four pairs of chisels which are pounded in due turn on the concrete surface under the action of the cams under tho driving sh?.ft. A gasoline- eneine supplies the necessary power. The machine travels alone at a slow rate of speed, smashing tho concrete pavement behind it.
