We learn from Messrs. Hamilton, the publishers of War Birds

: The Diary of an Anonymous Aviator, that the author is the late John Macdougal Grider, who was killed in the Great War. The diary has been edited by Mr. Elliott Springs, a fellow aviator of the. deceased. We are glad to publish this statement as substantiating the authenticity of a most remark- able human document, whose genuineness has been doubted in some quarters, although not in the review published in the Spectator of July 30th.
