Which of the following most accurately describes the problem?

T N AMERICA, as with us the wear of 1 road surfaces by the wheels of heavy road vehicles is a matter of serious consideration to the authorities, and different States and counties have instituted their own load regulations, much in the same way as is done here, the maximum permitted loads being regulated usually according to the width of tyre. In this country we believethat, although these regulations exist, they are often largely ignored, probably because weighing platforms are notalways readily avail-able and where the regulations are enforced, transport wagon owners often find it a 'difficult matter, with loads of a miscellaneous character, to akertain the actual loading of their vehicles.

In the States, they are probably worse off than we are in regard to weighing platforms, and in any case this difficulty has now been surmounted by the introduction of an instrument termed the Loadometer, which is made by a Baltimore concern. '

The instrument consists of an. hydraufie jack. The main chamber is filled with oil, and within it is a smaller-diameter

chamber in which operates a piston. The piston carries a top suitable for going under the axle of a truck, and forms the lifting portion of the jack, the exact adjustment being made by a lever-operated screw. It is only necessary, of course, that thewheel should be lifted just clear of the ground. With two.of these instruments operating at either end of the back4axle, the maminaum. axle weight can at once be ascertained, and it can also be ascertained whether one side of the wagon is loaded more. heavily than the other and, therefore, the amount of load per inch of wheel width on each wheel. To ascertain the gross load on the truck—the unloaded chassis weight being known—it is only necessary to apply the instruments first to the back axle and then to the front, the sum of the readings on the gauges telling the load carried, and by deducting the unladen weight from this the weight of the paying load is obtained.

The instrumeut is made M aluminium castings and weighs about 90 lb. Two handles are provided, by means of which it can be readily carried and the jack handles can be instantly detached, so that a pair of the instruments can be carried on the truck, or easily carried about in a small car by the inspector: The cost hereof a pair of these instruments, at the present rate of exchange, would work out at about 2100.
