valves about every 1.2oo miles, espe- cially the exhaust valves. The intake valves are not subjected to as much heat and require less attention. The quality of oil used and the mixture affect the valves. Perfect combus- ton of the mixture insures less valve trouble.
 For some time l have been a reader interesting and helpful. There is one thing would like to ask about my car. It is equipped with the westins- house self-starting and lighting sys- tenn. This. you know, has a separate instrument to charge the batteries. Lately the battery does not seem to charge. That is to say, the self starter seems to be weak in crankins the motor. which I believe is due to the weak battery. Do you suppose the battery is in need of repairs? I have kept the cells filled and take good care of the car. What do you think is the matter? Is 1t in the in- strument itself?
 It appears that the collector brushes in the generator need re- placing. If these are worn and do not bear firmly on the commutator the battery will be robbed of it's charg- ing. Perhaps by stretching the springs just back of the brushes you will ob- tain temporary help until you can obtain a set of new brushes. Of course, it will take some time to bring the battery back to normal again. Motoring Department, The Herald: Can you tell me what I can use on
 the brake band lining to make the
 brakes hold better? The lining Is
 not worn out and the adjustment is good, but no matter how hard I press on the pedal the car does not stop as 1 1t should.-Reader.
 Try using little belt dressing compound, such as is used to pre-
 vent belts slipping on pulleys In ma- | chine shops. You should be able to obtain this at most any hardware or general supply store.
 Motoring Department, The Herald:
 I have just bought 1913 four-cylin- der touring car, and am told to keep oil level in crank case up to P certain
 point. This means adding some oil
 every day. What I want to know is this: shouldn't all the oil be drained off once in a while? I don't know much about the engine, but this seems sensible. How often should the oil be changed?
 Thanking you for this information, I am-W. c.
 It is advisable to drain the case and use fresh oil about every 1000 miles. It is good economy to do this and also to use oil of the best quail ity.
 Motoring Department. Tho Herald; I bought this season a second hano car which the dealer said was a 1911 model, but which I now find Is a 1910 car. He also agreed to put 1t in first class shape, but failed to do so. What can do about ity
 The car runs fairly well on the level. but when climbing hill on high the car slows down and stops. There Is no play in the connecting rods. Could you tell me where the trouble is?-P. J. M.
 If your bill of sale specifics and de- scribes an article other than you re-
 ceived you have proof and should be able to obtain redress.
 It is a difficult matter to tell what
 the trouble Is with your car. Poor
 carburetor adjustment will make the car act very badly. If there is good compression in all the cylinders. and
 a strong spark delivered at each plug, you should be able to do much better l than you say. If the motor Is weak | in compression or has poor ignition system you can hardly expect any good results. Assuming that the car was demonstrated under various con- ditions, including hill climbing, to your entire satisfaction, it is possible 1 that you are not sufficiently familiar
 with the car to get the most out of it.
 If you drive with a retarded spark you will get no power. If the clutch slips you will have difficulty in climb ] (Continued on Ninth Page.)
