L-XPORTS ' of British oiI-engined
vehicles to South Africa are being hampered by a lack of fuelling facilities outside large towns. Vehicles used on long journeys often need. 50. gallon tanks for oil fuel. The. additional weight is not included itt the chassis weight, but is deducted from the payload capacity. •.
Mr. Sydney S.,Guy,.managing director of Guy Motors, who has just returned from South Africa, -saidon Monday that the, answer to the problemwas primarily one for the petrol companies. Their attitude was that they could not set up pumps in outlying districts if there was no demand for them. Mr. Guy said that he would take up the question with the Society of Motor Manufacturers and Traders.
Any operator whose vehicles travelled more than 20,000 miles a year effected large savings by running offers.
Mr. Guy said that American influence in South Africa was still powerful. He was certain, however, that there was a big demand for passenger and goods vehicles, but import restrictions would have to be relaxed.

NEW WORK BY RICARDO
ANY work on internal-combustion engineering by Sir Harry R. Ricardo, LLD., F.A.S., merits close study and the fourth edition of "The High-speed Internal-combustion Engine" which ha a been completely rewritten, is no exception.
In the first three chapters general principles are dealt with. Then follows a number of chapters dealing with combustion-chamber design of both spark-ignition and compression-ignition engines, cold starting, mechanical efficiency, supercharging, the two-cycle engine and mechanical design. The author has devoted 69 pages to the sleeve-valve principle, because of the extensive use of sleeve valves in aero-engines. Development and resear"ch are covered in the final chapters and as this material has been written round the work conducted in Sir Harry's own laboratories, it is raised above the level of theoretical computations.
Illustrations include a large number of pull-out line drawings, of which the draughtsmanship is in keeping with the high standard achieved in the work as a whole. The publishers are Blackie and Son. Ltd., and the price is £2.
