We welcome the appearance of The Air Annual of the
British Empire, edited by Squadron-Leader C. G. Burge (Gale and Polden, 21s.), for, unlike so many annuals, there is hardly a dull page in all this big book. The list of contributors is a distinguished one. Mr. Amery writes on the Empire, Sir Norman Leslie on Imperial Defence, Sir Alliott Roe on the reminiscences of a pioneer, and other contributors include Sir Sefton Brancker, Major Mayo, Mr. C. G. Grey, Captain Acland, and Mr. Ilandley Page, who writes of his famous anti-stalling device, now being adopted throughout the world. Sir Philip Sassoon writes a very short preface to the section on civil aviation, putting the pith of the matter in a sentence : " Sea communications built up the British Empire ; air communications must preserve it." Other useful features are the accounts given of each of the big aircraft firms and the reports of progress in the Dominions and Colonies. All concerned in the production of this important work are to be heartily congratulated; we hope it will find its way into schools and public libraries.
