Cycling and Motoring Notes.

From the Dunlop liubber Co., of Australasia, for the week ending August IGtii, l ( Jlu. * * * w *

The Dunlop Rubber Co. state that it looks as if some mistake has occurred rin connection with the belated result of the classic French motor ride- i lie Grand Prix that appeared in the press last week. Tin's important French race, the blue riband event of the world, was held on July 12th over a o(i!) miles course around the Amiens circuit, and resulted in a win for G. Jioillott on a Peugeot with J. Goux (Peugeot) second, and At. Chassigne (Sunbeam) third, particulars of the race being cabled to and published 011 Tuly 14th. It is now surprising to see a report issued to the press giving a totally different result, and what-is more peculiar drivers and machines are placed that were never entered for the race under notice, and were not included in the ballotted order of starting of competitors issued a week before the event. It is therefore verv evident that some error in translation or interpretation of a private cablegram lias led to the peculiar mistake. Possibly the results cabled last week refer to some other minor European contest, and they cannot' ever apply to the Coupe de I'Auto a Voituretle race (engine capacity •!,000 c.c.), which ranks as the second most important held in France, for that contest was, when ihe last mail left England, set down for decision .on September 21st. Another strange feature is that a speed of iS-'J miles is claimed to have been .recorded over the Amiens circuit, whereas when the cabled particulars of the Grand L'rix came through, the time given worked out at an average of 72 miles an hour. Therefore there is a difference of eleven miles in the two reports. Of course it is quite possible that a Deluge car driven by iialbot has averaged So miles an hour in another event over another and faster circuit (without limitation of petrol), but not in connection with the Grand Prix decided on July 12th. at Amiens. Both results io hand cannot very well be correct, for even if Poillot had been disqualified, Avhat has become of Goux and Chassaigiie!' 11 will be interesting to hear how the mix-up has occurred.

There art' indications that several of the large English manufacturing (inns, wlvo have not so far idenlified themselves avitli the cycle car side of the business, are likely to pay more attention to it at an early date. No doubt they have begun to realise that the deTnaud is a substantial one, and will inevitably grow when these little cars have been thoroughly tested and further proved. They are si ill in a staie of evolution, though Ihe developments up to the present has been most creditable.

That the cycle car is capable of standing np to hard driving on the road, even at a fast speed, has frequently been demonstrated in England, but the latest cycle car

performance easily overshadows anything yet accomplished in the Old Country. The severe drive from Lands End to John O'Groats (one end of England to the oilier), has been negotiated by aMr 11. Davies on a small Singer car, shod with. Duntop tyros in flic good time of -i-l 1 fours ; il) minutes. The distance is <S!jt) miles. 'I he motor cycle record for this classic course stands at L>!) hours minutes, also to the credit of Mr Davies.

Tlie effort to revive the Bathnrst Sydney road race has failed and this one time popular New South Wales road event Avill not be held (his vear.

E. H. Grul.)l), the English crack road rider recently made an. attempt on the English one-hour unpaced track record-and succeeded in covering 24 miles 1o4(i yards in that time. The world's record for this ride stands at 20 miles 400 .yards—to the credit of Oscar Egg, who put up this line performance in France.

An • American writes: While 1 it is often considered a fact that tyre heating is due largely to the compression, and consequent lieatiii ,< >• of the air, due to passing" over obstacles in the roads little consideration shows that this hardly can be true. It is well-known that while air is heated by compression it is cooled in an exactly corresponding degree by expansion. Therefore when a tyre strikes a blimp the air in it: is compressed and heated without doubt: but .immediaieiv the air • T- ~

resumes its normal pressure and temperature. It is usually considered that the _ heating of tyres is due to friction 'between- the tyre and the road and to the internal friction of the material of which the tyre is made. Friction between the cover and the tube also is responsible for a certain amount of heating.

The English Society of Motor Manufacturers and Traders- have just concluded one 01 the most iinpovtaui and far reaching pieces of work that they have yet undertaken, and one thai Avill be _ of considerable value to motorists generally. The Society named has decided on a standardisation of motor tyre rims, and as soon as the necessary gauges can be constructed 1 he whole of the English motor -manufacturers will fit only rims made to the measurements adopted by the Society.
