the post-war years. It is claimed that every pound of rayon saves two-thirds of a pound of rubber, because the rayon permits thinner construction. Another point is that tyres of which the carcases are made from this material do not develop so much heat.
qAFETY measures to mini mize accidents. have been introduced by a haulage concern, the Mason and Dixon As reported in " Transport Topics," the whole system is one of instruction and correction rather than of penalization, and it can be summed up in the phrase" Human-Relations." The safety department was set up early last year, and, at first, control was not pleasing to the drivers, but when each side understood the other there was no further trouble. The safety supervisors are' .hand-picked, carefully trained ex-drivers of the company, and they are unbiased in their opinions. Under them are some 170 drivers travelling through 12 states, and when a ,man is detected violating regulations he is stopped and reported to the safety director, who then recommends a penalty, if this be warranted. Whether or not this course be taken, the offending driver is called in to explain. Drinking while on duty is strongly An American System for Reducing Accident

discountenanced, as is the carrying of unauthorized passengers. The penalty for speeding is to lay off the driver for one trip for the first.offence, and for two trips for the second; a third offence .in a year may bring dismissal. Driviers involved in accidents are tried by a jury composed of two representatives of the management and three drivers. This jury decides whether the man charged is responsible. Coupled with this safety plan is a system of road foremen at strategic points, to handle roadside repairs. Accidents have been reduced by some 20 per cunt.
U.S.A. Hauliers ConMOT many tributes to road gratulated Through L transport are paid by American Radio . speakers on our B.B.C., but.
recently, in America, the N.B.C. network congratulated the members of American Trucking Associations on their important contribution towards victory. The speaker said that millions of Americans living in the smaller communities are dependent upon road transport for most of their daily .needs. Many of the largest cities also rely on this means for the carriage of all their supplies of milk. whilst 60 per cent, of the livestock tonnage of the country is hauled by lorry. Thus, even in normal times, mad transport performs services vital to tho welfare of the nation, whilst, to-day, it has the added responsibility of conveying enormous quantities of raw materials to .war plants and hauling a tremendous tonnage_ of war products from the factories..
A LL conscientious operators iThlook for maintenance points which will reduce fuel con: suroption. In this connection, the Standard Oil Co., of America, points to certain factors which waste petrol. They are as fallow:— Worn distributor points and improper timing; dirty air cleaners can reduce m.p.g. by as much as SO per cent, without giving any other warning; fouled or burnt sparking plugs may cut off the last mile in every 10; high level of fuel in float chambers and even a little wear on the float linkage and needlevalvemay cause considerable waste; an idling engine not only wastes fuel, but causes the formation of carbon, fouls sparking plugs and valves, and enforces more frequent " decoking."
