By THEODORE ROOSEVELT Here is Colonel Roosevelt’s own vivid narrative of his explorations in South America; his adventures on the famous “River of Doubt,” his visits to remote tribes of naked and wholly barbarous Indians, his 500-mile journey on mule-back across the height of the land between the river systems of Paraguay and the Amazon, his observations on the most brilliant and varied bird life of the South American tropics; hunting of the jaguar, the tapir, the peccary, the giant ant-eater, and other unusual animals of the jungle; all of this varied panorama is depicted in the author’s most graphic and picturesque style, full of the joy of new adventures. The book is a permanent addition to the literature of exploration. _Profusely illustrated. $3.50 net; postage extra._ Half Hours _By_ J. M. BARRIE From the delightful, romantic fantasy of “Pantaloon” to the present-day realism of “The Twelve Pound Look,” represents the wide scope of Mr. Barrie’s dramatic work. All four of the plays in this volume, though their subjects are quite diverse, are beautifully suggestive of Barrie at his best with all his keenest humor, brightest spontaneity, and deepest insight. _“Pantaloon,” “The Twelve Pound Look,” “Rosalind” and “The Will.” $1.25 net; postage extra._ HENRY VAN DYKE has written a new volume of poems: The Grand Canyon And Other Poems This collection of Dr. van Dyke’s recent verse takes its title from that impressive description of the Grand Canyon of Arizona at daybreak, which stands among the most beautiful of Dr. van Dyke’s poems. The rest of the collection is characterized by those rare qualities that, as _The Outlook_ has said, have enabled the author “to win the suffrage of the few as well as the applause of the many.” _$1.25 net; postage extra._ Robert Frank By SIGURD IBSEN Henry Ibsen’s only son is the author of this drama, which William Archer, the distinguished English critic, considers convincing proof that he possesses “dramatic faculty in abundance.” Mr. Archer defines it as “a powerful and interesting play which claims attention on its own merits,” “eminently a play of today, or, rather, perhaps, of tomorrow.” _$1.25 net; postage extra._ Artist and Public And Other Essays on Art Subjects By KENYON COX
