being put to practical commercial benefit. One of the latest examples is that Roadless Traction, Ltd., guarantees its rubberjointed track, as fitted to the Fordson-Roadless tractor, for one year, not only against faulty material and workmanship, but against wear and tear which, at the end of 12 months, will affect in any way the practical working of the machine.

RECENTLY at a debate held by the Institute of Patentees at Caxton Hall, Westminster, London, the subject was "Is Invention Useful?" We could suggest many other equally interesting and useful subjects for discussion, such as "Is Food Necessary?" "Will Red-hot Iron Burn If Touched by the Naked Hand?" or "Is Powdered Emery a Good Lubricant for Bearings?" Mr. Ralph Lynn would add much to the interest of the proceedings.

It so happens that the river Senne flows under the city, and it is proposed to divert the course of the Senne and to run the trams along the vacant culverts. THE sudden appearance of the "London coach ban" has set some people furiously to think, and the view held by many is to the effect that it is a prelude to the London Traffic Act.

MANY tall figures have been broadcast in connection with the huge Ford factory at Dagenham, but one item which convincingly stresses the size of the works is the amount of glass used for roofing. There are about 600,-000 sq. ft. of glass—nearly 14 acres—and where the roof is not glazed it is covered with a special protected metal coated on the inside with aluminium, thus contributing to the good illumination of the shops. A gang of men will be permanently employed cleaning the glass, narrow steel • O gangways being built into the roof to facilitate the vverk. It is possible to take a six-mile walk along these gangways without covering the same section twice.
