MAJOR SEGRAVE'S WONDER- FUL RECORD BREAKER

Motorists and sportsmen gen- erally will welcome the news that the Government has at last shown some sympathetic interest in an attempt by private enterprise to sustain British motoring prestige, says the "Daily Mail's" motoring correspondent.

The 1,000-h.p. golden motor-car, shaped like a giant fish, and thes 1,000-h.p. motor-boat, in which Major H. . D. Segrave will at- tempt (and has since wrested) from the United States both the world's land and water speed re- cords, were exhibited at the pre- mises of Messrs.. Rootes, Ltd., Devonshire House, Piccadilly, W., before their shipment to the United States.

They were inspected by the Prime Minister. Mr. Baldwin; the Home Secretary, Sir William Joynson-Hicks; the Air Minister, Sir Samuel Hoare; the Foreign Secietary, Sir Austen Chamber- lain, and Lady Chamberlain; the Secretary of the Dominions. Mr. Amery: The United States Am- bassador, Mr. A. B. Houghton, was. an interested visitor, as were Lord Cromer, Lord Esher, Major-Gen. J. E. B. Seely, and Sir Charles Wakenfeld.

Capt. Cambell's Effort Captain Malcolm Campbell left for. South Africa

on

a similar adventure. He is taking back this much-coveted record for Britain. I know- that his. car Bluebird which, like Major Segrave's car, is British to the last nut, has already cost him £20,000.

Major Segrave's car has cuati nearly £18,000, and there is the boat full of new and costly experimental features, in the testing of which the pilot must of necessity risk his life.

Major Segrave's expeditionis being financed privately by in- dividuals who are anxious to see the record won back for Britain.
