is the most difficult thing in the world
 to explain to an owner that it was his | fault and that these creaks never would l have happened but for his own treat
 ment of the car. But the chassis as well
 as the body of the car must be allowed
 to find herself as must the more sens-
 tive. more complex and more finely made
 motor.
 "The man who races his new motor
 or drives it at speed under full load is. | to speak plainly, a fool, and he's incur ring an expense account that will be appalling when it comes in. Of course, l he will never blame himself. He will talk about the man who made the car l Take the matter of expansion and con- 1 traction in a motor-and especially in the highest type of motor which we
 make nowadays-the one in which the cylinders are cast 'en bloc The big problem in this type of motor is the mat ter of contraction and expansion of the
 metal under the heating and cooling con- ditions. The heat being greater in the heads of the cylinders, the expansion ia naturally greater there than in the base and, if you heat the cylinders m rapidly, you will find that the walls no longer stand parallel, but that head of the engine has elongated perceptibly. But neat It up more slowly and the expansion IS uniform-because that's the problem on ''''Nti Nh7HiSSio D nave ldDOTeu longest and nave worked out most accurately. A bloc cast motor is the most expensive type Of motor to make. There are prob tcms-serlous engineering problenls-irl the design and manufacture of the bloc cast motor, but when she's once made she's wonderful. No repair man can mis- place the cylinders after taking them off because they are cast 'en bloc and the upper part of the crank case Is cast in- tegral with them
 Now suppose that the new owner would consider his car of steel with it's motor of cast iron, a thing of life-which It IS. highly sensitive, beautifully made. accurately machined piece of mechanism that must be handled care tully until 1t has found itself And suppose that, instead of treating his neighbors to ride at full speed in the new car, he derives still more pleasure rom a nice quiet jaunt 15 to 20 miles an hour with the silent motor purring just loud enough to be heard and the feeling of her under the steering wheel, something to make every nerve jingle. Suppose that instead of wickedly over heating his motor in the first half hour or his drive, he gives her the power gently, gradually, so that she heats up slowly, evenly and lets her cool down slowly with the radiator still full of the warm water, to which it has been unnecessary to add any cold
 Why, that man will have a motor that you can't kill, whose life will be 1O 15 yes, 20 years-no one knows how long good motor properly treated will last
 And his car-what of the car? h. stad Of being a creaky. secondhand af- fair in few weeks. the car which has been carefully driven until it has found itself will not develop any squeaks and noises because there will be no fra Each part has been given the opportunity to yield just little, and the parts have yielded uniformly instead of being forced to break at some point.
 And don't let your first trip in your new car be thousand-mie iarnt throuh the White moutains or across the continent.
 1magine any railroad superintendent sending new locomotive on long haul the first time. Why. it's an unheard of thing. Or letting nav engine assume the whole load of running the factory. Impossible,
 Just think of the difference between that and the average case of a new auto mobile in the hands of buyer His mechanical skill usually is limited to his ability to write a check. That done the car paid for, he takes an hours lesson from the dealer, and then expects his car to stand anything. The wonder is that they so frequently do
