When undercoating was developed, it first sprayed this in the conventional manner, but, later, also the interior, making the inner coating about in. thick, and covering it with a lining of plywood. The result was a 50 per cent. saving in the ice, which can now be preserved for more than 24 hours during garaging. Incidentally, the vehicles operate "much more silently. The undercoating material was also used on steel tread plates as a successful non-skid to prevent drivers slipping.

Vehicles which Cruise 1-1. Ralph Cropper, writing in at 55 M.P . H The Road Way" concerning his recent tour in America, might well stagger some of those people who are objecting to a 30 m.p.h. limit for heavy motor vehicles. He travelled 2,800 miles on haulage vehicles from Denver to the West Coast and back, and he said it was a grand experience, moving day and night on machines carrying 25-ton loads at 55 m.p.h. That was the cruising speed on the flatter roads, but steep mountain slopes had also to be negotiated; despite these, this great distance was covered in eight days, an average of 350 miles daily. ALTHOUGH the motor 1-1* industry depends so much on the various products derived from crude oil, few people realize the difficulties sometimes experienced in drilling the wells. In "The Lamp," published by the Standard Oil Co., of America, reference is made to some of the special instruments and devices employed. The " photoclinometer " indicates which way the hole is deviating from the vertical and at what angle. It is a long tube with a compass, a graduated glass under which moves a steel ball like a bubble in a carpenter's level, and a tiny camera that photographs compass, ball and graduated glass together. The instrument is lowered and the pictures taken by remote control. The " dipmeter " gives the direction and angle of dip of the geological formation under study. It shoots three separate waves of electricity towards the surface. These are reflected,
