HIGH SCHOOL CHILDREN BUILD TRACTOR Enterprising high school youngsters of the Pacific coast have completed a molortractor which they are operating on one of the war gardens. The pho tograph shows the completed tractor as it first appeared on the school grounds. MOTORISTS FACE PROBLEM OF GAS Automobile and Petroleum Men Must Get Together in Close Harmonious Co-operation. INCREASE IN MOTOR CARS Said to Be Possible to Construct In ternal Combustion Engines Which Will Consume Much Less Fuel of Inferior Kind. "The perennial fuel problem will nev er be solved until the automobile Indus try and the petroleum industry get to gether in close and harmonious co-op eration," says Mark L. Itequa, general director of the oil division of the Unit ed States fuel administration, in an interview, which appears in Motor, the national magazine of motoring. "The motor fuel problem is not only a possibility of the future," contin ues Mr. itequa, "but even an actuality of the present, as will be understood by anyone who takes the trouble to make even the most cursory examina tion of the situation. In 1912 our pro duction of petroleum was 222,935,044 barrels of 42 gallons. In 1916 the out put of this basic producer of motor fuel was 300,767,158 barrels, an In crease in four years of less than 30 per cent. On the other hand, in 1912 there were about 1,000,000 motor ve hicles in the country, while in 1916 the motor population ol' the United States had risen to 3,541,738. This represents ap Increase of over 300 per cent in four years. With one side of an equation growing less than 30 per cent and the other side increasing more than 300 per cent, the ultimate situation is not hard to foreshadow. Engine Uses Less Oil. "I am not an automobile engineer, so I cannot speak from personal knowl edge, but I have been informed that it is possible to design internal combus tion engines which will consume much less fuel per mile than is now being consumed, and of a much inferior qual ity. If this is a fact and the automo bile Industry faces the Situation in co operation with the oil men to effect this saving, while these latter are de voting their best effort to increasing production, it would seem that we might cut enough off each end of our problem to solve It. "We seem to be only at the begin ning of the gasoline era; a few years ago gasoline was a wasted by-product; today it is the most important product of petroleum, amounting to almost 50 per cent of the total value of petroleum products. AY!Ih the record of the past as a guide, it would seem that the two great industries so interdependent up on each other should co-operate in bringing about the most efficient con sumption of gasoline and the most in telligent understanding of each other's problems." CARE OF WINDSHIELD GLASS Application of Strong Soapsuds Will Prevent Fog or Rain From Obscuring Vision. Strong soapsuds made from auto mobile soap and rubbed on the glass of the windshield and allowed to dry will prevent fog or rain from obscuring the vision through the glass. Kero sene is sometimes used for this pur pose, but it does not last as long as the above, and glycerin is also recom mended. AVOID FORMATION OF RUST If Car Is Used in Bad Weather Tires and Rims Should Be Wiped Clean With Sponge. If the car owner, after being out in bad weather, will take the trouble to •vipe the tires and rims clean with a sponge and then wipe them dry, espe cially along the beads, he will do much to prevent the formation of rust.

TROUBLE IS MOST ANK3YINS Noises Frequently Occur in Springs and Spring Shackles if Neglected and Allowed to Run Dry— Hoods Are Offenders. "Squeak, squeak," said the car, and again it said "squeak, squeak, squeak," while the driver pondered unmention able thoughts. "This is one of the most annoying troubles while driving a car that is otherwise in good condition," says William H. Stewart, Jr., presi dent of the Stewart Automobile school. "The squeak may not be anything seri ous or it may indicate a trouble which may grow to be dangerous. In any case it gives the sensitive motorist no rest until it is removed. "If the noise occurs when you apply the brakes it is evidently in the brake bands, but other places are not so readily located. For instance, if the car squeaks when you go over water bars and other jounces the trouble may be in the springs, the spring shackles, the mud guards, fenders, where the body rests on the frame, or a multi tude of other places. Squeaks in Springs. "But squeaks frequently occur in springs and spring shackles, particu larly if neglected and allowed to run dry. In order to prevent this these parts should be gone over and thor oughly greased at frequent intervals. Jack up the frame to take the weight of the car off the springs. Spread the leaves apart, one by one, prying them open with a cold chisel or a screw driver with a metal handle, using a medium weight hammer. The process will chip off some of the paint, but this is unavoidable. Now spread graphite grease between the leaves, using a thin-bladed knife or a hack-saw blade. Use cylinder oil mixed with a little kerosene to reach in farther than you can force the grease. This will fre quently stop a squeak that cannot be reached by the grease alone. "In rare cases the springs will have to be taken off and the leaves taken apart to give them a thorough oiling, particularly if they have been neglect ed for a year or more and have become badly rusted. There is a special tool on the market for spreading spring leaves. This may be used to advan tage. Other Offenders. "Hoods and mudguards are frequent offenders. Inspect the strips of raw hide on which the hood rests. If these are broken or missing they must be re placed. Close down hood and see if it touches metal at any place. If it does a squeak is sure to develop. Stand on the spring hanger or the run ning board and shake the car up and down. This will ceause the squeak to start, and it is then merely a matter of injecting oil into all places where metal or wood may rub together. If possible tighten the parts and elimi nate the cause. An oil gun, with which a heavy oil may be injected with con siderable pressure is a great help. Fol low the whole length of the mud guards, the bottom and sides of the hood, the hood fasteners, where run ning board and mudguards join, the radiator supports and every likely and unlikely place. "If the brake band squeaks place a little, a very little, grease on drum in space where end of brake bands join. This will be carried into the lining and help stop the squeak. But use very little, as grease is not noted for its tendency to make ifrakes hold. "Keep at it and try again. Shake the car to draw the oil into the places mentioned, and go over the work again ; and again until success crowns your { efforts." , Making Adjustments. Never make adjustments of any kind on the engine unless it is hot. This applies as well to carburetor and Ignition work as it does to valves or | other parts. HANDLE BATTERY WITH CARE Motorist Should Economize on Cur rent and Keep Engine Tuned to Start on Second Turn. The man who has trouble keeping his battery charged will find that dif ficulty largely can be overcome by careful handling. In other words, he should economize on current. He should keep his engine tuned up so that it starts on the second or third turn. Thus he can minimize the amount of current used in starting, and, remember, this is very large. The current required is 200 to 600 times as much as required by an ordinary IG-candle power house light. He should also be economical with his lights. He should use his head lights only when absolutely necessary. He should determine the car speed at which his cutout relay makes con nection with the battery and operate the car as much as possible above this speed. If he drives much in a congested city district ami stops his engine many times he will find that his battery can be kept more nearly charged by chang ing gears in traffic whenever neces sary instead of trying to do it all on high gear, the reason being that by changing gears he boosts his engine speed so that his battery is charged, while if he tried to pull slowly on high he gets down to a speed at which charging stops due to the opening of the cut out.

DELICATE CAR DOOR POCKETS Wooden Strips May Be Securely Fast ened by Using Blue, Round headed Screws. Many cars are afflicted with "deli cate" door pockets, those which are made of inferior material or are Im properly fastened. These are apt to tear loose at the corners since they are merely tacked on wooden strips at tached to the door. When this hap pens they may be securely fastened by using round-headed screws, which should have blued heads when the ma terial is black. These same screws can be used to advantage in fastening the linoleum flooring to the boards, especially at the corners. FIND LUBRICATING FAILURE Car Owner Should Emulate Example of Locomotive Engineer by Using Hand to Find Trouble. The locomotive engineer frequently uses his hand to determine lubrication failure, and this is i hint that the car owner can put to good use. Failure of lubrication permits excessive fric tion, and friction generates, heat. Any part which is discovered to be too hot to the hand held near it is prob ably suffering from faulty lubrication. Music Not His Strong Point. Tht' leader of a volunteer orchestra was greatly annoyed by the 'cellist, who repeatedly at a rehearsal was in error; finally he stood near him, lis tening. "Why, man," he exclaimed, "your 'cello is not in tune!" The player screwed at the pegs, but a few moments later the discord was re peated. "Can't you tune your instru ment?" demanded the conductor irri tably. "No-o!" said the stout 'cellist, "not always." Then his face bright ened. "Rut you should See how I can skin fish!" The skinning of fish was his trade, the orchestra his side line. Invisible Airplane Wings. Wings of cellulose acetate, being transparent, make an airplane invisi ble at the height of a few thousand feet, also increasing the operator's field of vision. Sheets one one-hun dredth-inch thick are about as strong as the ordinary wing cover, and the weight of nine ounces to the square yard is but slightly greater.

David Stirling, lieutenant-to-be, climbed the hotel steps wearily, ac knowledged mechanically the greetings of the usual porch squad of people, and dropp"d into a chair —comfortable, but far from the madding crowd. Seven times he had repeated these motions with the same dejectedness, the same absent-minded manner, the same weary dropping Into a chair. Immediately afterward, the heads of the rocker brigade would meet, and the buzz of whispering voices arise, some sympathetic, some mildly angered. Scraps of sentences drifted to Dave's ears, such as, Too bad! Poor fellow. It must have been her fault." "1 wonder what the quarrel was about anyway." Some maintained that it was not her fault, but his fault. David tried to remember their names for fu ture reference. In the meantime, on this seveutb day, Dave lit a cigarette and stared moodily out over the sea and sky. spread lavishly before him as if to console him with their beauty. For a time, the poetic half of his nature re sponded enough to Isolate him from his disturbing thoughts. The sky was like turquoise, he thought, the sea like sapphire, the clouds and foam were pearls—but at this point his mind wan dered to diamonds —engagements — girls—one girl in particular. And he was back again in the world of his troubles. For the seventh time Dave reviewed the chain of events. Two weeks ago he had come to spend a month at the quiet summer resort In Maine to be near Carol Thatcher, his fiancee, before he left for the South ern training camp. The first week had been Elysium, Utopia, and heaven all combined. Every night marked the end of a per fect day. Bathing, boating, fishing walking on soft grass or cool pine needles or luxuriant white sand, not on hot pavings or coblestones. And then —one day he was to meet Carol in their favorite spot, a large, cleared spot in the woo
