which replaces the ordinary Diesel, engine for surface use and electric motors for under-water operation. We have an idea that this must be our old acquaintance, the Erren hydrogen engine. In this system, the power unit opetates on oil fuel when the boat is on the surface, and while doing so also provides electric power for the pressure-electrolysis of. water, with the result that the oxygen and hydrogen are disassociated and can be stored, while still under pressure, in ylinders. When the engine is operating on hydrogen, the oxygen replaces the air which would normally be employed, and comlistion results merely in the production of steam, so that no exhaust bubbles are formed'. The remaining oxygen --Serves as a supply for breathing.
Are the Germans Developing the Hydrogen Engine ?
wrni the spread of canteen facilities the need for unscheduled bus stops while drivers and conductors procure refreshments is steadily diminishing. In this development many undertakings are working on the assumption that comfort in canteens, in addition to food, brings a good return. An excellent' example is the recently 'opened central canteen of the Dublin:
United Transport Co., Ltd.' There the facilities resemble those of an ordinary restaurant, with small tables, white tablecloths, flowers, white-coated boy waiters, attractive decorations, and a good cloakroom. Dublin Transport also has smaller enterprises in twoof the garages. In every instance the company puts in all equipment and pays overhead expenses, 'including light and heat, so that what the men pay for meals represents only the cost of food and service.

Why Not More THEoil engine is, apparently, Tanks with Oil in high repute in the Royal Engines Tank Corps. Men who are
continually dealing with these machines have informed us that those equipped with oil engines give a considerably better performance, are easier to maintain, and, what is more important still, are not subject to the same fire risks. The use of a highly volatile fuel in a Tank has always struck us as being the extreme of foolishness, particularly when there may be four carburetters, a blow-back in an of which might feasibly result in a conflagration.

Why they should not cycle the short distances involved is a question which local residents are asking. In the samearea, refuse-collecting vehicles have been seen standing for fairly long periods with their engines running while the loa,ders get on with their job. Sometimes there is no one in charge of the vehicles, which in itself is an offence in the circumstances.

The fear is expressed, however, by the S.M.M. and T. that this situation is not receiving adequate attention, for there is a serious dearth of apprentices. With a view to remedying this position, the Society has requested the Board of Education to impress on public and secondary schools the importance of technical training and to make more widely known to their pupils the facilities offered to engineering apprentices by the Government. The Society is also in touch with other bodies which may be interested in this matter.
