MOTORS AND MOTORING

(By "Oluteh.") Hot Weather Risks. Slackening a tyro in hot weather to minimise Hie risk of a blow-out may easily bo carried too far. "Whon a tyro la run under-inflated in hot weather to combat air-expansion," one' , authority remarks on this subject, "you really increase the bending of the tyro and. inoidentally creat more boat. Fabric separation usually results from this weakening of the cotton fabric; and you aro treated to the unwolcomo sound of the blow-out. Hundreds of tests Jiavo proved that no tyro is in. danger of blowing-out because of hot wither expansion of air, and wo recommend keeping tyres inHaled to the. standard pressure." Aeroplane Comparisons, It is always- easier for motorists to realise aeroplane, .performances if they can be reduced to motor-car equivalents. They aro more likely to bo impressed with, tho information that au aeroplane will climb at sixty miles an hour than if they are told its rato of ..ecension . is 1300 odd feet per minute. As a matter of fact, a good modern aeroplane, weigh- j

ing, all on, about 24cwt., and having an engine of a brake horse-power of. 180, would climb a gradient of 1 in 3£ to 1 in i at about sixty miles an lour; that is what rapid aerial climbing really means. Twenty-tour hundred-weight is about.tho same , weight as an average 15 h.p. fourseated opon car complete, but without its passengers. A good many of the aero, planes now in iiso weigh inoro, and a few eomowhat fes. To Oil Springs. , An. emergency trick for oiling a spring is to go over it with kerosene, wiping off tlio dirt as you do so, and guiding the keroseno down tho leaves so that it will run in between the leaves. Wipe off the 6urplus. Pour oil over them, guiding it down the eides the same.way. It is led in by (he kerosene and oils tho leaves very effectually. Now rock the car or jump on the running-board and your springs will be fairly well oiled. The Best way to oil a spring, how. ever, is to remove it and take it apart, scraping or filing off all rust and covering both sides with graphite, grease, or oil. This is troublesome, but is the best in the end, Coasting. American hints on coasting.—When coasting • down a long hill, change from one rake to the other to allow them to cool.- Unfortunately this does not cool the brake drums. So use the motor as a brake and go down very steep hills against compression. Leave the gears in the high-speed, or, if you-find that too fast, the second or first speed. Stop tho ignition and ; it will cool your motor at the same time. ■:■•"' Coasting down a long grade with many curves is dangerous -unless you know the road, especially if the ear be running in neutral. - Deep'sand, a wet spot in the road,- or any one .of a number of conditions might be met that would require quick work to .prevent an accident. Tho driver has better control if 'the engine is running and the clutch engaged. A Wairarapa Enterprise. In their second annual Teport the diTectors of the Mutual' Insurance Com, pany, formed under the auspices of the Wairarapa Automobile Association, record . a prosperous year. The company ;aa not yet sustained a losSj and the financial position is steadily improving. The directors have decided to again purchase War Bonds': to the extend of .£2OO (face value .£240) in anticipation of next year's revenue.. One hundred and eeveneen cars are now insured by 102 certificate holders, the total amount covered bein? d 618,625. Tho balance-sheet showed the receipts" for the year to have been 165., and the expenditure 11s. 9d., of which .£lB3 Hβ. Id. represented the bank overdraft at the beginning of the year, created by reason of an advance for an investment in War Certificates, thus leaving a credit in hand of is. 3d. The assets total J441 19s. 10d,, including War Certificates for .£4OO (face value..£soo). At the annual meeting , Messrs. P. C. Bunny, W/ Benton, and W. A. Hntton were re-elected a 9 directors, and, with Messrs. 'BL A. Bunny and F. Feist, represent the policyholders. Mr. J. M.-G. ITKenzie was re-elected auditor. It was resolved that a rebate of ss. per cent., on the basis of the premium, of £2 per cent, for their insurances to original members, be again granted, and that all policies be written down on a basis of 50 percont. of that adopted by private companies; the scale for this company to be: 10 per cent, for a car one year oldi and 5 per cent, additional for each succeeding year; no insnrance to exceed t5 per cent, of the value of a car, as por purchase price or value as written depvp. A motion: "That the'memorandum antl articles of associa- j tion 1)6 amended ii) ennblo tho -company , to insure members (if desired) against (1) damage by accident, (2) third party risk; and that the directors bo authorised to \

settle the conditions and premiums." A was _di6cußsed at length and supported by six votes to four, hut thn maiority not beinjj in accordance ivith the i'Cnuirements of thoiCompanics Act, it was | declared lost. Hore and There. ... 1 It is a good pliin to tako olf all of 5 your tyres about onco in six Tuonths, test all tho tubes and clean tho rime ( with a wire brush. Tho rust should, bo removed thoroughly and the rims ccalod with graphite. Dα not allow grease, oil, or acid to remain on your tyros. Prevent blowoufls by ■ avoiding sevoro I jolts and maintainiing fnil air pressure. Always cross Tailroad tracks in second speed. Ton will, of course, rrin over them slowly to avoid danger to the tyres, I but tho motor is easily Btalled when 1 throttled 'down oa. high speed. Cross j them in second speed and you will bo j safer. ■■' ■. i . ■ ■ 1

Carry sparo tubpe in a bag. Be sure that nothing on tho anachino 6crapc6 the tyres us they revolvo. It is so unpleasant to crawl under a car to placo a jack in position wlujn n tyre ohanßo has to bo mado, and ko difficult to find a proper lodging-place for tho jack on (he under gear, that it haa been euggeatod that a stand similar in operation to those used on motor-cycloa be fitted as- part of tho standard equipment of a cwr. With, such a stand tho car could be jacked vp by its own power, and much trouble and annoyanco a.oid. ed. It would seem that such a stand ■would bn raHher heavy and cumbersome, but possibly t-oino gonitis could overcome these objections. . To removo a light deposit of carbon, pour hydrogen perosido through air valvo of carburetter while engine is running. Use at least a pint. Thig is much better than kerosono or alcohol used the same way.
