DRIVING A CAR ON WASTE WOOD [To the Editor of
the SPECTATOR.] Sim,—On page 900 of your number dated May 29th, 1928, there is an interesting article on " Driving a Car on Waste Wood." The writer may be interested to know that during the War, when fuel was scarce and dear, exhaustive experi- ments of the kind described by him were carried out in Egypt by the late Mr. John Wells for the Egyptian Government. He ran several motor lorries on gas derived from such materials as cotton stalks and other cheap combustibles. An inquiry addressed to the Mechanical Transport Department of the Ministry of Transport, Cairo, would probably elicit some helpful information on these experiments.—I am, Sir, &c., SYDNEY H. DAVIDSON.
