Wolseley Cars.

The 6-h.p. light car has been produced to meet the demand for a light, two-seated vehicle that can be easily driven, and looked after by the owner without necessitating the employment of a chauffeur, and with this view the design has been worked out on the simplest possible lines, while the con-

struction is of a substantial character, making the car a most serviceable one for hard wear and tear m all weathers. This type of car has been largelyadopted by doctors and professional men for business purposes, as by its use it has been found possible to effect a saving of many hours in a day's work.

A vehicle of this type can also be fitted with a hood and weather screen, so that the passengers are entirely protected in bad weather. Since its introduction, this car has been most successful, and has secured the highest awards in various reliability trial runs and hill-climbing competitions. Two styles of body are made (Roi de Beige bucket seat and phaeton), either of which may be fitted at the puchaser's option. The selection must be made when the order is placed. The 8-h.p. tonneau is a new improved type of light, four-seated car, capable of maintaining a good average speed on the level, and possessing excellent hill-climbing qualities. This car has lately been entirely re-designed to supersede the old 7^-h.p., and is now practically a small mode] of the 12-h.p. car. The wheel base has been lengthened, and particular attention paid to the suspension of the car, thus making it very smooth and easy running. The motor and gearing are entirely enclosed and protected from mud and dust by a

detachable shield. The chassis is so arranged that all mechanism lies below the frame, thus making it possible for many different styles of body to be fitted. The 12-h.p. tonneau car is shown fitted with the type of body most generally used, and is one of the most popular motor vehicles in use at the present time. Since its introduction, this car has always been conspicuous for its consistent

reliability and hill-climbmg qualities. It is purposely constructed as simply as possible, without sacrifice of efficiency, so that it is possible for the owner to quickly learn how to drive and attend to what adjustments may be needed from time to time. In public reliability trials and hill-climbing competitions during the past three years Wolseley cars have created a remarkable record, having secured eleven gold medals and two silver medals in open competition with every well-known make of car. The chassis is so arranged that all mechanism lies below the frame, which makes it possible for any type of body to be fitted.

Prosperity is shown m the balance-sheet of Argyll Motors, Ltd., which shows a net profit of on the year's work. Among the assets are the new works at Alexandria, valued at and new machinery plant, etc , a total of £122 173.

Diamond tools have been ably discussed by Mr. G. C. Hennmg before the American Society of Mechanical Engineers. It appears that hard rubber paper, hard stone, and hardened steel cannot be readily worked by the use of steel tools. Tools of a much harder material are required, and for this reason diamond is used. The diamond is of two kinds, totally different m appearance and quality. Black diamond has a very dark purple brown colour, is an amorphous, granular stone, with rarely anycrystallisation visible or traceable, and is called carbon or black diamond. It is the hardest material known, and has great strength. Bort, on the other hand, is entirely crystalline, and generally transparent, and of all colours of the rainbow. Some are as clear and transparent as glass, and this kind is considered harder than any other bort, except some which is almost black. Bort is extremely brittle, and is readily fractured or split in the three directions of its cleavage planes parallel to the sides of the octahedral crystal, in which shape it is most commonly found. The dodecahedral crystals are also readily " cleaved "in a similar manner. In spite of the very great hardness of all kinds of diamonds, they are readily sawn, drilled, cut, and polished ; carbon (black diamond) cannot, however, be polished, as is the case with bort. Diamond cuts diamond, while steel saws and drills and cast-iron discs, charged with diamond dust, are used for the other operations. All kinds of grinding wheels, being made of extremely hard materials, are most readily kept free from filling or glazing, and imperfect shape by diamond tools. In certain classes of work, where great accuracy and precision are primary requirements, or extremely fine lines are essential, the diamond is the only material that answers the purpose. Thus lithographers, engravers, and scalemarkers use them for fine work.
