car and by a simple movement or HIS
 hand prime the engine with hlgnly volatile fuel that will give a lire at
 the first shot. This equipment con sists of a small tank which contains a pint or so of the lighter fuel. This
 tank is connected with the various cylinders by means of pipes or leads
 A small plunger pump is placed on the dash. by manipulating which the driver sends spray or the heH fuel into the cylinders, where IL IS fired bv the spark and starts the en-
 ,ine after which the ordinary fuel is abIa to care for continued operation.
 Now a word as to the best fluids 10 use for priming purposes, as this IS most important if satisfactory results are to obtained. The commonest pri"- ing medium is probably what IS known as 76 degree gasoline. rms IS siihplS the lighter gasoline that we used op tain all the time. but which Is now rare luxury Within recent years some of the oil companies have been puttihs out what is known as petroleum ethei. This is simply a lighter constituent derived from the crude oil base Witn a tank of this fuel it is possible to get first time start even in zero weather Some owners have made a practice or using ether for winter starting, put this has obvious disadvantages Either the 76 degree gas or petroieuin elher will be the pest SldTtlIiS ihco1uHi.
 Of course. it is always possible to prime the engine with ordinary gaso- line. The assumption in this case IS that enough of the lighter products Of the ordinary gasoline will get into the cylinders to allow the spark to fire the charge If the lighter forms or prim- ing fluids are not available, ordinary gasolene should certainly be tried.
 Almost all car owners know that by cnlfn porization is completed or rather ac- ceIerated, so that the fuel is easily fired. This was the reason behind the old fashioned custom of filling the cooling system with boiling water on cold mornings. The heat thus impart- ed to the engine served to yaporize the fuel a little and insure An easy start. This method ts too tnconveni- ent to suit modern motorists, however, and there are devices now on the mar ket to secure heated fuel in less way. The equipment to which we refer embodies an electric heater. SO placed that as the fuel is pumped into the manifold it is passed over a heated coil, being thereby va porized so that easy starting is almost certain.
 This question of starting is rather uncertain at best Some car owners seem never to have any trouble. They
 
 ply the choker and get start the first time. The choker is left on for a couple of minutes and is opened as the engine warns up. To these fortunate a scant minority, our ad- vice is not directed, but for the vast | a little help will prove wei l come.
 When the car is equipped with cleo ] rica1 starting apparatus, it is v1tally | important that this shall be main | aimed at maximum efficiency during | he winter months. This is obviously | rue: since the fuel is heavy and slug yish with the cold, a good hot spark | s needed to fire it and this can only | ,e obtained from battery in perfect l order. It is vital that the bat cry be kept fully charged or nearly so md that the cells be filled with dis filed water. an operation that must be attended to once every two weeks. The park gaps must be carefully watched md kept properly spaced.
 And even s.fter the start is obtained t is still important in cold weather to tive the engine as much heat as pos ibIe The carburetor should be heated md should get hot air to make sure of | we'll vaporized fuel. The hood and ra- liator should be covered when the car s left standing. Give the engine aR
