It was only in his youth that John Ruskin was in the habit of "dropping into verse" and the Poems which are included in the Universal Edition of Ruskin's Works, of which E. P. Duttou & Co. are the American publishers, were all written between the ages of 15 and 26. They have a delicate touch, and some of them show a surprising mastery of the technique of verse. An introduction is supplied by Mr. G. K. Chesterton, who is always diverting, whatever his theme.

“Angel Esquire," Mr. Edgar Wallace's new novel, is a story of a treasure guarded not only by deadly devices but by a cryptogram which the author leaves unexplained to madden the careful reader. A gang of burglars and murderers; a lawyer, apparently the soul of integrity, but really worse than the gang; a baronet in disguise, and police officers of high degree contend over the treasure, and Angel Esquire, detective, sits up aloft and outwits every body to the reader's entertainment. As a tissue of impossibili

A delightfully intimate contribution to the knowledge of Mr. Gladstone's character is made in the slender vol. ume “Mr. Gladstone at Oxford" (E. P. Dutton & Co.). The writer, the only clue to whose identity is found in the initials C. R. L. F. on the title-page, was resident at All Souls' College, Oxford, during Mr. Gladstone's famous visit in 1890, and being thrown into close association with Mr. Gladstone during that visit, and being a close listener to his remarkable conversation, conceived the happy thought of writing down every night, for the information of a devoted admirer of the great statesman, all that he could remember of the conversations and the incidents of the day. It is these informal letters which make up the present volume. There are portraits of Mr. and Mrs. Gladstone.
