whether many people realise their own power of helping on the war. One fruitful source of economy lies in the use of envelopes. When a business man consigns four or five hundred envelopes to the waste-paper basket every morning —about 95 per cent, of them almost as good as new—he rarely realises the waste involved. This is brought home to us by the invention of a simpl£ device called the " Save-tun " label, by means of which one can use envelopes over and over again. It is impossible to conceive the ultimate economy effected by such a device, but an instructive example is the case of a town of say, 800,000 inhabitants where about two million letters axe posted each week. In the course of a 12-month a single town of such dimensions would effect an economy of about 80 million envelopes, representing many tons weight of paper and paper-making material for which cargo space has had to be provided. If every community in the country adopted this device, it is almost impossible to conceive the economy that would be effected and the resultant benefit to the cause of the Allies. Not the least of the advantages of the " Save-tun " label is its use in connection with corre- spondence with our soldiers. The boys in the line frequently experience great difficulty in obtaining envelopes, but if a " Save-tun " label were slipped into each letter to the front, this difficulty would be removed, to the delight not only of Tommy but also of his friends in the Old Country. Even the private individual who writes a dozen or so letters a week, can appreciably assist the country towards a successful issue out of its existing troubles. Kenrick and Jefferson, Ltd.—who are responsible for this innovation—are providing the " Save- tun " label in small packets of 150 (is.), so that it is equally available for private use as for commercial purposes. The firm's show-rooms in London are 22, St. Andrew Street (off Holborn Circus), but they also have show-rooms at Man- chester, Liverpool, Cardiff, Swansea, Birmingham, Newcastle, Leeds, Leicester, Sheffield, Glasgow and Belfast. H H LEGAL INTELLIGENCE, Aircraft Petrol Tanks. %-'""~: -•:»~* W( AT the Mansion House, on August 19th, before Alderman Sir John Knill, David Assersohn, metal-worker, St. Bride Street, appeared on three adjowned summonses, alleging that he had committed acts in relation to a gravity petrol tank likely to render it partially ineffective, and making statements and withholding information calculated to deceive persons in the Ministry of Munitions as to its quality. From the evidence it appeared that the defendant was given a sub-contract by Savages, Ltd.,for the supply of gravity petrol tanks for aeroplanes. From the Government's specifica- tions, he made a specimen tank, but it was rejected as being double-grooved, and not riveted. Later on the defendant pre- sented a number of tanks, which were accepted, with one exception. This one wasidentified as that originally rejected. Rivets appeared to have been put in, but they were " blind rivets," and they fell out when a soldering-iron was applied. For the defence it was submitted that no offence had been committed, as the tank had never been supplied. Of th e tanks submitted, all but this particular one passed the Government inspectors. The specifications had been, altered and varied since the contract was entered into, and the tank in question was one of those originally submitted. BftWitnesses were called, including the defendant, who testified that gravity tanks were stronger and more efficient when double-grooved and sweated than when riveted. Major Parnell-Smith, Lieut. Raven, and Lieut. Gough, of the Aeronautical Inspection Directorate, spoke to the excellent quality and accuracy of the defendant's work. Sir John Knill said that the defendant would have to pay £100, with £21 costs, on each of the three summonses—£3^3 in all. The prosecution was a very proper one. It was stated that the defendant would appseal to the High Court on a point of law and to the Quarter Sessions on the facts. PUBLICATIONS RECEIVED.
