The importance of good con- Buctors in electrical work, and especially . in radio where high frequencies and high potentials are customarily used, has been shown in the preceding articles. It is, however, equally important to have nonconducting or insu- lating materials in order that tlectrie currents may be confined to well defined and limited paths. Such materials are 'commonly called insulators, and when used in conjunction with condensers, dielectrics. In order to prevent the current from escaping along sny bypath before the desired terminal point is reached, it is a familiar fact that elpetric wires are covered with layers of cot- ton, silk, rubber and other non- conducting compounds, and are supported on porcelain knobs or in clay" tubes. ost insulating substances show a decrease in volume with in. creased temperature.

How Wobbling Tires Wear Themselves Ous They Are Bimply Side-SNpping All The Time HOW OFTEN I'T HAPPENS that one or both of the rear tires} of the car ahead of yours is seen to wobble! Is it possible that the driver just behind you notices the same thing about your ear? You very 'rarely gaze upon the rear of your own car, when it is moving, and perhaps it would be worth while to do this in order to find out if you have a "wobble also, for a failure of a rear tire to run true and to confine its movement to the plane perpendicular to the road surface, is destructive to it and also wastes power. On firm-surfaced roads at ordinary speeds, unless on sharp curves, the tires have a pure rolling motion upon -the road, without slippage und without the rubbing effect that tes it, but a wheel that wobbles is constantly side al its tire and "sand. papering" off its tread. Suppose a rear wheel, t does not run true, Is jacked just off the garage floor and given a complete turn, it is easy to mark on the floor the extreme positions atspied by the outside of the tire, which is the amount by which it runs . Perhaps this 1s found to be three inches (which is by mo means extreme) and since the car as a whole does not move from side to side, as the wheels turn, it 1s evident that this tire side slips on the road, three inches each revolw tion. In the case of a 82-inch wheel, which moves the car ahead prac. tically 100 inches per revolution, the side slip is 3 per cent. of the for ward movement, so that on a 100 mile trip, the effect of the wobbling on the tire would be equal to that which would have been produced if the wheel had side slipped or skidded a distance of about three miles--a rather striking fact and one that makes very clear why a wobbling wheel scuffs away its tire tread in & very short time. A tire may fail to run true simply because the rim which carries jt is unevenly mounted on the felloe of the wheel, or is itself sprung, but this does not account for extreme cases of wobbling. These are generally attributable to the Wheel itself being a warped surface--not a plane--or to its plane not being at right angles to its hub axis. The worst cases, however are the gesult of'the bending out of line of the outside end of the axle shalt, So that the wheel is driven in a wobbly manner. VALVE TIMING DATA MUDGUARDS HIT TIRES Answer: We cannot tell you Where you can obtain this data in book form. As manufacturers o0- casionally alter the timing of thely timent in England, where many peo- ple became panic-stricken at the notion that such a hole beneath the channel might invite invasion by a French army. This feeling held not- withstanding a proposition made by the French Government in 1885 to build part of the tunnel at the Calais end above water, so that British war- ships could, in case of war between the two countries, blow it to smithe- reens. The project, indeed, may be said to date back to the days of the first Napoleon. For in 1802 a French en- gineer suggested to him the idea of attempting an invasion of England by boring a hole under the channel. The great Corsican thought the mat- ter over, but decided that the plan was hopelessly visionary, Nevertheless, in 1869 the Calais to-Dover tunnel was actually begun, and $600,000 was spent in di § shafts at both ends. It was planned at that time to propel trains through it by compressed air, in order to avoid the smoke of steam locomo- tives, and a scheme was partly work- ed out for employing the tides to furnish power for the purpose. Now- |i adays, of course, there would be no difficulty of this sort, inasmuch as the electric locomotive would solve the problem satisfactorily. All the plans for the tunnel-- |i which eventually, it is likely, will be |i twinned--were made and completed |i long ago. As an engineering enter- prise it does not offer any very |i extraordinary dificultiés. If the bot- tom of the English Channel were of unsubstantial material, mud or silt, the job would be one of a most trou- blesome character; but, as a matter of fact, it is a smooth floor of chalk, swept clean by the rapid current passing through it from the North Sea. The stratum of chalk is over 200 feet thick. It affords material of great density and uniform consist- ency, yet easy to bore through, and watertight. It is reckoned that a tunnel eighteen feet in diameter can be dug by machinery at a rate of nearly four miles a year. To finish it will take five years, and the cost will be about $2,000,000 a mile. The to- tal expenditure should not exceed $77,000,000, and returns from traffic ought to yield at least 6 "per cent. to investors in the enterprise, Olicloth Fishing Moats, The oldest form of fishing boat is the coracle, which is still used by fishermen in the Cardigan district of West Wales. Coracles were used by the ancient Britons. They are very fragile, being made by covering a wicker frame- work with leather or oficloth. They hold one man only and are propsiled by means of a hand paddle. When fishing, two of these craft work to- gether with a net slung between them, At the present moment coracle users are disturbed by the Fisheries Act, which controls the number of net licenses issued and empowers fishing boards to select the indivi- duals to whom licences may be grant- ed. If this act passes Parliament, they declare, coracle fishing will be- come extinct.
