Broken stone of a depth of 5 ins. to 8 ins., and consolidated, forms the base. It is covered to a depth of about 2 ins, with chippings coated with bituminous emulsion.

advertisement spread contained in a recent issue of the World's Press News. It is stated in this that 95 per cent. of the paper supplied to publishers in England by this well-known concerti is delivered by motor lorry, thus ensuring minimum transit damage. Incidentally, the vehicle depicted is an A.E.C. Mammoth Major Mark II.
Will Synthetic Rubber CONSIDERABLE progress

thetic rubber, the first tyres made of which were referred to in our report of the Berlin Motor Show in February. The material is known as Buna, and it is said to be characterized by great resistance to petrol, oil, heat, wear and atntospheric influences. Russia is also greatly interested in the production of synthetic rubber. rE flow of air past models iln a wind tunnel can now actually be seen at the National Physical Laboratory. It is rendered visible by the production in the air current of a number of tiny electric sparks, which heat up little spots of air. A shadowgraph of these hot spots can be produced by suitable illumination and photographed by a cinema camera, taking photographs at the rate of 2,300 per second.

Road Transport ReIN connection with the history sponsible for a lof the Pickford undertaking Famous Brew . (given in a recent issue of The
Commercial Motor), a correspondent reminds us of an interesting point. In the time of Matthew Pickford, one of his competitors in the Derby district was a certain William Bass, who was a carrier between that town and Burton and Ashbourne. Among Bass's best customers was a Burton brewer, and the obvious success of his business gave the carrier an idea; he would set up as a brewer himself, and deliver his own beer ! Thus was started the enterprise that has since become world-famous; Bass's carrying interests Were afterwards disposed of to the Pickford firm. Thus two Midland carriers of the 18th century established names that are now household words.
HINTS on ascertaining engine condition are given by Lodge Plugs, Ltd., which states that if the electrodes and cavity be coated with a soot like lamp-black the mixture may be too rich ; if white and parchedlooking, too weak, or there may be fuel starvation caused by a defective pump or obstruction in the system. Wet oil indicates worn piston rings, bores or valve guides, unless caused by definite over-lubrication. A wet, broken carbon formation may point to a leaking cylinder-head gasket, or even a porous casting.

Bus Service at Sydney THE Berlin Press is exercised to Collect Sleep 1 over a bus which authorities
Walkers at Sydney, Australia, have commissioned to parade throughout the night to collect steep walkers at large in the city. Sometimes, declares Berlin, whole families go somnambulating, so bad has the epidemic become. Police report every day that they have picked up dream-wanderers, men and women, in pyjamas. To cope with this difficulty, hospitals are said to have organized a sleep-walkers' motorbus patrol. just now a medical congress is in session at Sydney to ascertain the cause of this remarkable wave of " dream wandering."
