THEROU.NDUP 9 The back axle is in two parts and the gears in the differential are so arranged as to allow the machine to turn corners where one wheel moves faster than the other. On account of the heat made by the exploding gasoline vapor the cylinder must be cooled or it will become so hot that the charges ignite at the v ' rong time. ater cooling is made possible by casting a jacket all around the cylinder and water is kept circulating through it either by heat or a pump. Some engines are air cooled and the flanges casted on the sides of the cylinder allow more sur- face to be exposed to the air, thus keeping it cool. ARTHUR lOON, 1910. Fare thee well, dear Great Falls Fligh School, Four short years were spent with thee ; And our paths will soon be severed, But our hearts will loyal be. We look with pride and fond affection On the dear old White and lUue, And to teachers now, and schoolmasters, The Nineteen Tens must say Adieu. E FRANCES KIRWIX, ' -1910.

8 THEROUWDUP Gas or gasoline vapor will not explode unless mixed with a cer- tain amount of oxygen. The device that does this work is called the carbureter. It consists of two separate chambers made of brass, or glass ; a float chamber, in which the flow of gasoline from the supply tank, is governed by a cock or hollow brass float, which operates a needle valve; a vaporizing chamber, where the gasoline is mixed with the required amount of oxygen. A feed pipe runs from the carbureter to the ignition chamber, through which the vapor is drawn. The charge of gasoline and air being in the cylinder, it must be ignited at the right instant, so we can get a full amount of power from the explosion. The two most common igniting systems are the induction coil and high tension magneto. The coil consists of a coil, contact breaker, primary and secondary winding mounted on the dashboard. The battery used may be either dry or storage, and is usually carried on the step of the machine. The coil changes the low battery E. M. F. to an E. M. F. high enough to jump a small air gap inide of the cylinder. The spark plug is a small gap built in porcelain or mica and fitted to screw in the opening meant for it in the cylinder head. One side of the secondary is connected to the iron work of the engine and the other side is connected to the spark plug. Now when the chauffeur cranks or starts his engine, he turns the main shaft with a crank, the main shaft turns the two-to-one by gearing mentioned before, the cam on the two-to-one shaft opens the mtake valve and when the piston goes down a charge is pulled into the cylinder. Now when the piston comes up, it compresses the mixture, the spark occurs and the mixture, rich in gasoline, explodes, driving down the piston. The Kinetic energy of the fly-wheel on the main shaft keeps the wheels turning until the next explosion. The timer is a little device, controlled by a small handle at the driver ' s seat. The timer is run by the two-to-one shaft also, and in it the contacts are so arranged that the spark takes place just as the piston starts down after the compression stroke. By turning the small handle at the wheel the time of the spark is advanced or re- tarded and the engine runs faster or slower as desired. The clutch is the device by which the engine shaft may be con- nected or disconnected from the driving shaft. This is usually oper- ated by a foot pedal. The clutches in use today are the cone, mul- tii)le dice, and friction. Some form of transmission is necessary in order to change the speed of the auto, so that we can climb hills and then again have it geared high so as to speed up on the level. Between the clutch and back axle is located the tranmission. A handle at the driver ' s seat enables him to slide certain gears on one shaft to mesh with certain ones on another, so the different speeds are picked out. If the ma- chine is shaft driven, this shaft after leaving the transmission gear case, runs to the back axle and terminates in a bevel gear, inside the differential.

10 THE RObxNDUP The T ilgrim ' s Progress And it came to pass after nv 1 ad wandered for about eight years among the Primary and Grammar fields, with their restrictive limits, and he Iiad come to be about fifteen years old (in socth, he knew his age exactly, since he was a iKiy of parts and ranged from thirteen to eighteen years of age), he came to a greater gateway than he had yet seen, and height— G. F. H. S. Now, like all of suc-h age, he was curious and would know what these mystic letters did mean, and what this gateway did keep him from. And. urged by his parents, his curiosity, and his desire to learn, having heard it said that this was the gateway to knoAvledge, he entered through and into the field. And behold, there were three others there, and they called themselves Nine- teen Seven, Naught Eight, and Naught Nine, and thej called to him, asking his name. And he answered as a matter of course. ••Chingalanga, chingalanga, chow, chow, chow, Boomalanga, boomalanga, bow, wow, wow, Chingalanga, boomalanga, who are we then? We are the class of 1910. At which clever verse, Nineteen Seven and Naught Nine, not recognizing poetic genius in the sounding lines, did laugh and spitefidly jeer, and Naught Eig ' ht did help him, and the two scoffers were speedily vancjuished in a joust of stars and crescents. But he had now reached the Slough of Desjjond and did pine and become greatly decreased in flesh ; and, having devoured almost all the dates, and hav- ing heard rumors through the land of a great trial, called E.xams, to be held on the farther side, he did gather cour- age, and, girding his gown of knowledge about him, and accompanied by divers books and papers, and bestriding a pony, it came to pass that he came through the slough and trial much the worse for wear, and the pony wanting, but with a longer head, and a broader view of fairer pastures before him. And he did eat of some tempting fruit called dime novels, and was warned, and he took the narrow path, and was sent a companion Helpful, in the shape of di- vers teachers, and when imprisoned in the castle of Despair, with a long list of English questions and inks and a pyramid of paper. Behold, after some time had passed and he was to be exe- cuted the following day, he did bethink himself and in the recesses of his mind did find a key to the great door, and its name was Work. And he kept this key ever with him, and he has conquered, for lie soon will pass into a larger field of not only knowledge, but wisdom. Like Ichabod, he bent but never broke. Where he did conceitedly strut before a small com- rade, Seven and Naught Nine did come to Seven ' s aid, and the two did beat our hero woefully with stars and cres- cents, he did not cease tO ' aunt little Seven, and he did ever quarrel with true brotherly feeling with Seven, who was come to be a great youth, by following the tracks of Nineteen Ten; and Nine- teen Ten goes faithfully to fresh fieldsi and pastures new, to find other worlds to concpier and to forget or not realize his defeats, and make the most of his victories. I have finished. It is well. lARGARET KOLBENSON, 1910. IVhat Is Going To Happen? When the returns first a])peared in the paj)ers. it did not seem possible that the SuciaVists could have won such an overwhelming victory in Milwaukee. Tlie Social- Democratic candidate for mayor, f mil Seidel. won by the largest plurality ever given to a mayor of that city. Their candidates for comptroller, for city treasurer, and fur city attorney were elected. They elected twenty-one out of thirty- five aldermen. Still it cannot be called purely a So- cialist victory. It is, rather, an uprising of the people against the machine rule under which Milwaukee has been labor- ing for so long. Democratic politicians claim that Republican errors caused the Socialist gain. Republicans say that the
