the Germans indicate that throughout the war a very considerable amount has been supplied to them
 Engineer Guiseltn. secretary of the International Commission on Petro- leum, has recently made public In Paris an estimate of these supplies Before the war there were large stocks in storage in Germany and the Ger mans have been able to use the pro- ducts of the fields in Roumania. A1- sace and Hanover, and with the ex- ception Of the time during which the Russians occupied Galicia-of the Galician fields as well
 Before the war Galicia was produc- ing 72,000 tons a month and during the early months of the war this was increased to S9,000 tons. The Russians are known to have destroyed 229 wells during their occupation, but many of commission have doubtless long ago been restored.
 Roumanian expectations of petro- leum in 1914 amounted to million tons. A large amount of the capital employed in the operation of the Rou- manian fields is German. Germany is the third consumer of petroleum in Europe and before the war was talk ing about 120,000,000 tons annually.
 Roumania has enforced a decree for bidding the exportation of those parts of the crude which can be used for motor spirits or the lighter oils. The figures Indicate that while Germany has been inconvenienced by the short age of the supply and has been forced to develop intensively the wells in her field of influence, she has still in all probability been able to get what ever she needed for her army.
 Motorists who do considerable driv- ing in crowded traffic, naturally op- crate the clutch and brake pedals more than the average driver, and the continual rubbing of metal and the soles of the shoes will quickly wear the leather. Caster oil applied to leather soles will soften them and add greatly to their wearing quail ties and better convenience the driv- CT. The soft sole shoe is much to be preferred to the heavy sole, as with the thin and faxible leather the oper- ator can "feeP' the pedals. The soles of new shoes can be treated, increas-- ing their endurance and your com fort.
 In the smaller provincial towns of England women taxi drivers have be- come common since the war develop ed and are pursuing that business with apparent success. Whether they could be successful under the more severe traffic conditions of the large cities is yet to be determined.
 The change in the grade of lubri- eating made by experienced motor ists to meet the different conditions under which motors are used should not. be made exclusively on a basis of weather. The condition of the engine should chiefly be taken into account.
 When motor is new is has as near perfect compression as possible and whether it Is winter or summer it should use the same grade of lubricant successfully. When a car has been run several thousand miles mechanicals wear takes. place and There have been a number of charts made for choosing oils, putting em- phasis exclusively on weather condi- tions rather than on the condition of the motor.
 A new machine for preparing the soil for crops which differs in a revo- lutionary way from the blow and har- row that have been used without change in principle since Pharoaf's time, is now being built commercially.
 This machine Is known as a rotary tiller and was invented in Germany by K. V. von Meyemburg. 1t is designed to do the work of the blow, disc and harrow, in one operation, fully pre- pairing the soil for the crop.
 Whereas the blow cuts, lifts and breaks the soil. the rotary tiller or soil miller makes chips like a hoe and breaks them into small pieces by throwing them against each other. The blow when used must be followed by a series of other tools to make the one operation. It pulverizes the soil to the full depth even when the earth Is comparatively heavy.
 Featherweisht pistons are guaran- teed not to crystalize on the dome, aTy fvn fva &hn r.fvN kA enlargement o the ring grooves, re- gardless of length of service. They are made of aluminium alloy, which Is stronger than cast iron, and will not score the cylinder walls. A set of these pistons for a certain car weigh present cast iron set weighing 12 pounds. Featherwefght pistons tend to reduce vibration and afford a si- lently operating motor when running at high speeds by eliminating tre- mendous pounding strain on the bear ings. This piston metal has been thoroughly tested and found efficient by use in the mapority of this years racing cars. Four sizes of pistons for this car are carried in stock by the size, .031 for rebored cylinders and .033 oversize for rebored cylinders.
 The increasing popularity of con- vertible types of motor car bodies has served to emphasize the features of convertibility heretofore found only in high priced cars and now carried | to a higher state of advancement by a few manufacturers who specialize in fine body work. In fact, the inter est in convertible bodies is second l only to the interest in the important | general improvements of the year.
 The practice of keeping cars in ser- vice all winter has grown. apace with | the increasing knowledge of the du- ties required by cold weather and the | facilities for making win ter motoring comfort. The result | has been demand for two types of | equipment-that which is applied to i a touring body for the purpose of | enclosing 1t and that which is orig | inally built to combine In one model | the open air feature of the touring | car with the protective features of the limosine.
 While the convertible types conn monly used are applied rather than embodied in a unit design. the grow-aI ing appreciation of custom work has given wider expression to creativel genius with the result that new types of bodies, essentially high priced. are now being built for those with whom | the price Is not necessarily a con-
