 If you find that a valve is really the source of the trouble the best thing to do is to remove it and send 1t to an experienced repair man, who will either replaee its with a perfect one or repair the defect It is not ad- visable for an amateur to tamper with valves.

 Leaks In the manifold are often de- tected by a wheezing sound caused by the gas escaping. If a leak is known to exist but cannot be found ip this manner, it may be located by squirting oil over the joints near the cylinder and around such places as the spark-plug holes. compression cocks. etc. when the engine is run ming. Bubbles will appear at the leaks. A leak in the intake manifold will make the mixture SO lean that backfires sometimes result.
 A good repairman never overlooks the condition of the pistons and rings but where the carbon has been clean ed out by the owner himself they are often overlooked and is soon trou- bled with a sticking ring. This trou@ bic is very common and is we'll known to most automobilists, but still, day after day, there are others who not only let the rings get into this con- dition, but who also break them when attempting to take them off to clean. It is necessary to free the sticking hnmediaf ely or the tightness of the cyiinde- will be impaired.
 When tire cuts are of considerable size 1t is inadvisable to attempt to repair them with patches, since they will not hold. The only remedy in such cases is to have the tube vul- canized by some one experienced in this class of work However, in cases of emergency when on the road and the damaged tube is the only one at hand, it is best to effect repair with patch in preference to run ming on a flat tire or on the rim. The puncture of large proportions so mended will not last for long, but no doubt 1t will be permanent enough to carry the cars weight until the first garage is reached.
 The movement of gasoline prices during the first half of 1912 was a continued rise: The year opened al 40 cents a gallon for tank wagon lots of automobile gasoline of -68 to .72 s. O. This price advanced to Il cents late in January, a month later to IF cents and thence practically cent ev- cry 30 days, until it is now Is cents An obvious reason for this advance is the ever-increasing demand for auto mobile fuel which stands face to face with a limited supply. This latter is regulated by the production of crude oil, the supply of which cannot be so increased as to easily fill the demand for gasoline without an overproduc- tion in other petroleum products. To balance the increase in oil stock neces- Eitated by. a larger gasoline output, the oil producers have increased the price on petroleum steadily during the past half-year.
