SUDDEN ENDING OF THE BUSY LIFE OF TWO TOURING CARS. traffic is frightful. These accidents may be classified as those due to ignorance and inexperience, carelessness, and high speed. The most common kinds of accidents are collisions, burning, and turning turtle. The reader always has a feeling of relief when he notes that "no one ne was injured." As to whether or not his feelings are of mirth, revenge, or sympathy depends upon the nature of the accident, regardless of the damage done. If the driver leaves his car standing in the street without attention to a flooded carburetor that soaks the pavement with gasoline, and then some children come along and throw lighted matches into the oil pool, and the car is burned to junk, the reader does not think exclusively of punishing the children. If an inexperienced driver rushes through a crowded thoroughfare and when attempting to make an S-curve around a hurdy gurdy, turns Of all the vicious habits of an auto, that of "turning turtle" is the most destructive. The machine literally runs away with the driver. kicks up its heels, dumps the riders, and unfeelingly jumps onto them, unmindful of its own destruction. The skidding and turtle effects depend upon the car speed and also upon the engine and wheel action. This latter may be traced to the gyroscopic effect of the revolving parts. This force seems to cause the car to jump into the air, make a sort of a screw-like wriggle and to somersault. Speeders should beware, or the turtle will get you if you don't watch out! It is said that it is the stopping and not the going that hurts. Did you ever compare the force in the stopping from falling off a building with that from the stopping in a collision? For instance, at twenty miles per hour the speed is about the same as the velocity when landing from a thirteen and one-half foot fall. If the gait is forty miles per hour, the equivalent drop velocity is that from four times thirteen and one half, or fifty-four feet per second. For a real joy ride of sixty miles per hour, which is a speed of eighty-eight feet per second, a sudden stop means the same as dropping from an eight story building, or one hundred and twenty-one feet. The danger, mathematically speaking, increases directly as the square of the speed. Thus at twenty miles it is four times as great as at ten miles; at thirty miles it is nine times; at forty miles it is sixteen times, and at sixty miles it is thirty-six times that at ten miles. Yea, verily, the auto is no child's toy. AN AUTOMOBILE BEDROOM. MONROE WOOLLEY. It is an easy matter to convert a touring car into a bedroom. All that is needed is a few square yards of heavy canvas and eighteen or twenty pieces of tough lumber half an inch thick by one and one-half inches in width. The length of the strips of lumber should be about six feet, or as long as the size of the car will permit. The strips are tacked at intervals of about an inch, or an inch and one-half, between two layers of the canvas, thus forming a mattress that may be rolled up into a compact bundle for carrying on the side of the car. For sleeping purposes this mattress is spread or rolled out across the backs of the seats making a level surface on which two or more persons may lie down. By using quilts for padding and blankets for covering, this apparatus makes a comfortable bed in which to sleep over night. A piece is cut from A MODERN PRAIRIE SCHOONER. the lower left hand corner of the mattress to permit it fitting snugly around the steering wheel. By using cushions, blankets, and pillows, cozy sleeping quarters may be arranged for small children in the lower part of the bed of the car, particularly in the rear portion. Ten years ago very little rubber was produced in the far East. Today its production is fifty per cent greater than that of Brazil. THE IMP MAGNETO. The Imp is said to be the smallest make and break magneto in the world. It is intended for small engines where it would be difficult if not impossible to mount a magneto of ordinary size and price. The accompanying ilustration shows the Imp mounted on a 1-horse power engine. The mag neto is only four inches wide, and easily fits between the fly wheel and crank where other magnetos could not be placed without the use of an intermediate gear. A bracket is provided with Imp magnetos made to fit over the bearing cap of small engines. This makes the installation of the magneto very simple and cheap. The Imp is made by the Sumter Electrical Company of Sumter, South Carolina, and owing to its manufacture in large quantities it is sold at a very reasonable price. It has genuine tungsten steel magnets, a laminated armature, solid brass end plates and bearings with oil grooves and covered oilers, a substantial base, a grounding brush, a non-turning circuit terminal, and every feature necessary for long life and satisfactory service. The company's Chicago office, 1413 Michigan Avenue, has some interesting literature regarding this new magneto, which can be had on request. It would be a good thing if Congress or some other body which has jurisdiction, would make it unlawful for the general educational board or any other board representing private interests from pensioning public servants like college teachers. If there is any one thing above another that should be kept absolutely above the suspicion of selfish domination it should be our educational institutions. A German scientist has succeeded in obtaining laboratory temperatures within 1.8 degrees of absolute zero. Hart-Parr Oil Tractor and Hart-Parr Self and Hand Lift Plow doing a fine job of Fall plowing. You Wouldn't Use a Tin Spade for Gardening Then why do your fall plowing with horses and expect the best results? Or why neglect it, when a Hart-Parr Power Outfit will do it on time and put more money in your pocket at harvest. The horse is a weak, unprofitable tool for plowing or for other heavy power work on the farm. He is costly to buy and costly to keep. He requires almost constant care, especially when working. He creates a lot of disagreeable barn chores that demand your attention after you have put in a hard day in the field. His power efficiency is low in comparison to what he consumes. Heat and flies make his efficiency still lower. He tires easily and soon wilts under a blazing sun. And worst of all, when you plow with horses, you are merely scratching the surface of the soil, instead of turning up new plant life. You can't get good results that way. It's different when you do your fall plowing with a HART PARR & HART-PARR A Hart-Parr plowing outfit earns a profit every day you work it. Its first cost is low and its up-keep cost remarkably small. A little care each day keeps it in good condition and ready for hard service when you are ready. It develops its full rated power on CHEAPEST KEROSENE, works steadily in hottest or coldest weather and never tires even on a 24 hour shift. And best of all, it goes into the field and easily plows 6 to 8 inches deep, turning up new crop fertility and does this when conditions are just right. There are few delays with a Hart-Parr Hart - Parr Co., 246 SELF AND HAND LIFT PLOW Power Equipment. You operate the entire outfit right from the engine platform, save the plowman's wages and board and save yourself a lot of heavy drudgery. This same tractor is also an ideal outfit for the other power jobs on the farm-discing, seeding, harrowing, harvesting, threshing, hauling, etc. In every way, it's a profit earning investment. We have some intensely interesting facts and figures for the farmer who is dissatisfied with the "horse farming" habit and the farmer who is anxious to make his farm pay bigger returns.

Distillate то O plow two thousand acres of land is quite a task, but when the most of that two thousand acres is heavy adobe soil, the task is immense. If you have ever seen real adobe, you can't realize exactly what it is, but imagine a sticky black soil almost as hard as a rock that turns over in great chunks, and you have a fair idea of what it looks like behind the plow. It would be impressed upon your mind more fully, however, if you could fire a big tractor pulling a gang of six or eight plows. It can be bought in one hundred gallon casks for nine cents per gallon while gasoline in a similar quantity sells at seventeen cents per gallon. Mr. F. E. Keppel, the assistant manager of the ranch, has figured that the cost of operating the big engine is about twenty-five dollars a day. In a ten-hour day the plows turn over about sixteen acres. The cost per acre is about one dollar and fifty-six cents. The gasoline tractor turns over about seven The Cotati Land Company of Sonoma County, California, owns two thousand acres of hay land, all of which is this heavy black soil. Two engines are used, one a Hart-Parr gasoline tractor, and the other a Russell steamer. The steamer has a rated horse power of 120on the brake and 60- on the draw bar. It has been made to develop as much as 90- on the draw bar, however. The gasoline tractor has a rating of 45- on the brake and 25- on the draw bar. It pulls a gang of four twelve inch plows and the big steamer pulls eight fourteen inch plows. Distillate oil is used in both engines and a considerable saving in fuel results. Both gasoline and coal are high on the coast and the fuel bill is nearly cut in half by using the distillate. acres in ten hours at a cost of ten dollars, or one dollar forty-two cents per acre. This comparison should not be taken to indicate that the gasoline tractor is more efficient than the other, however, because these figures are so close together as to be about equal if absolutely accurate tests were made. In figuring the work of a tractor in acres, there is always more or less of a variation one way or the other. And, too, in figuring the cost of operation, there is a chance for a difference of a few cents one way or the other on different days. One advantage he steamer has over the other engine is that it will develop a little extra power in a tight place, while the gasoline tractor will go only to its limit and will then stop. The manager has met with some unusual diffi |
