The Employment of r ONCERNING the use of Rubber for Heavy N--" rubber in vehicles, a little Loads point came out at the first Scottish meeting of the I.R.T.E. One member advocated the employment of more of this material, because it saved the use and subsequent exudation of grease, which he considered an awful thing to have around the garage. The lecturer pointed out that, to be used properly. it is most desirable that the rubber should be in compression. When employed for such places as spring shackles, unless the rubber be forced in to obviate excessive loading at one point, the limited area of high pressure will cause it to squeeze away and eventually permit metallic contact. The problem is easier with light vehicles than with heavy ones. Express Carriers to THE Group Committee of Discourage " Pool " I the express carriers, now Licences forming patt of the R:H.A., draws attention to applications for A or B licences now being made in connection with various traders' pools of vehicles. When a number of these pools was being set up during the war, the National Conference of Express Carriers, at that tirne. viewed the matter with concern. and through the Standing Joint Committee arranged for representations to be• made to the appropriate authorities. The developments which the Conference then suspected might occur have come about, traders formerly asking for C licences are now applying for the A or B class. The Group is, therefore, urging express carriers to lodge objections and to emphasize that existing carriers can meet all traders' needs. ii You Want Results A LEADING man in an Come to "T he " important organization

Such a result is indicative of the readership value.
Safety First in the T" question "Are vehicle Maintenance of Vetexaminers less fussy than Maintenance of Vetexaminers less fussy than erans. they used to be?" was asked by
a newspaper representative at the recent Ribble Press conference. He had assumed that this might be the case because there was much talk of old vehicles still in use and of the difficulty of obtaining spare parts He was rightly informed that the standards of inspection are as rigid as ever, but operators are painstaking and ingenious in maintaining even the oldest vehicles, so that safety is assured even if mechanical tosses may occur. Chances might be taken with a crankshaft, for example, but never with a steering drop-arm or anything so vital as a brake connection.
What Are the ProsTHE possibilities of the peels ol Magnesium A magnesium accumulator are Accumulators ? . . . being fully studied in America and Canada. According to British light-metal experts, a capacity of 10 to I in terms of weight is theoretically possible. The chief difficulty appears to be in obtaining magnesium of sufficient purity; an impurity forms what may be termed permanent "couples," causing the accumulator to act in a similar manner to an expendable battery. If success can be achieved, such an accumulator would prove an enormous asset on batteryelectric vehicles.
