“Mr Koebel is essentially a writer sympathetic to the lands of which he writes. What his book loses in depth it gains by virtue of this sympathy, by its author’s earnest desire to see things from the South American angle, without in the least abandoning the attitude of a man alive to the defects of those whom he is describing. It is a stimulating work by a sane and just writer.”

“Mr W. H. Koebel’s last addition to the, by now, rather lengthy series of books which he has written on Spanish-America, is disappointing.... He obviously knows as well as anybody that the problems are there and call for answer. But he does little more than indicate their presence, and then wander in generalities and descriptions, not without occasional repetitions.”

The author calls attention to the great dissimilarity that still prevails in the junior high school movement in every aspect of organization and function. He holds that the experimental stages of the movement should now be reviewed and stock be taken of the current opinions and practices, with a view towards clarifying thought as to its peculiar educational purposes. With an introduction by Henry Suzzallo the contents are: The movement for reorganization; The peculiar functions of the junior high school; The test of the organization; The program of studies; Other features of reorganization; The standard junior high school; Tables and graphs.
“In six chapters Professor Koos has presented an analysis which goes to the heart of the junior high school movement. The book is a striking example of what can be done by way of giving information without becoming drearily encyclopedic.”

KOSSOVO; heroic songs of the Serbs. *$1.25 Houghton 891.8
20–10292
These ballads, translated by Miss Helen Rootham and printed with the original on alternate pages, come with an introduction by Maurice Baring and an historical preface by Janko Lavrin. Mr Baring says of them that their colors are primitive like those of the primitive painters, their similes are taken from a first-hand communion with
the sights and facts of nature and their emotions are the primitive emotions of man. But their soul is saturated with the Christian faith of the Crusaders and they sing the sorrow of Serbia, the unspeakable anguish of a people who are victorious in defeat. In the historical preface Janko Lavrin divides the Serbian folk-songs into four groups of which this, the Kossovo-cycle, deals with the heroic battles fought on the Kossovo plain against the Turks. The songs are: The fall of the Serbian empire; Tsar Lazar and Tsaritsa Militsa; The banquet on the eve of the battle: a fragment; Kossanchitch and Milosh: a fragment; Musitch Stefan; Tsaritsa Militsa and the Voyvoda Vladeta; The maiden of Kossovo; The death of the mother of the Jugovitch; The miracle of Tsar Lazar.
“Miss Rootham’s simple and dignified translation makes it possible for English readers to appreciate the heroic quality of the originals.”

“English is not very well fitted to cope with it and, just as Longfellow often failed in Hiawatha, so Miss Rootham often fails to get the swing of the trochaic measure. The original is so rich in alliteration, often rhyming with vivid flashes of poetic figure, that it is impossible to reproduce its magic effect. It requires a poet to translate poetry; mere knowledge of a foreign tongue does not communicate the magic of words, and Miss Rootham’s version, while useful, will hardly satisfy the exacting lover of Serbian poetry.” N. H. D.
“The poems are vigorous and give a pleasing view of what really fine work has been done in Serbia.” H. S. Gorman

The author is an Armenian who has dropped his real name for a more pronounceable signature. The book consists of a series of “selfconscious” essays wherein the author under the guise of reminiscences discourses on men and writers, women and love, on death, friendship and modes of living. It is a book of moods also and the writer fits in the subject or person to fit the mood. The chapter vignettes are from drawings by Michel Sevier.

Professor Ladd also describes the social customs of the people and outlines some of the political reforms that are demanded by the native leaders.” R of Rs

The author is secretary of the Intercollegiate socialist society and editor of the Socialist Review. The important service of his book is that it gives an up-to-date treatment of the new developments in socialism and relates them to the movements of the past. It covers “the socialist criticism of present day society, the socialist theory of economic development, the socialist conception of a future social state and the activities, achievements, and present status of the organized socialist movement in various countries of the world.” (Preface) It is divided into two almost equal parts: Socialist thought, and The socialist movement. The work is intended to serve as a textbook for college classes and study groups, and “ as a ready reference book for the thinkers and doers who have come to realize that an intelligent understanding of this greatest mass movement of the twentieth century is absolutely essential to enlighten citizenship.” There is a select bibliography on socialism and allied subjects, and an index.

The “hero of the longhouse” is the historical Hiawatha, an entirely different person from the legendary figure in Longfellow’s poem. The real Hiawatha lived in the fifteenth century, was a member of the Onondaga tribe and was one of the founders of the League of the Iroquois and the author has drawn her story from the most authentic sources, chiefly from Horatio Hale’s Iroquois book of rites and manuscripts in the New York state archaeological department. Arthur C. Parker, state archæologist, writes an introduction, and there is a bibliography and glossary. The story has been told primarily for school children.

The American exploration society sends Captain Gray to the Desert of Gobi to find the lost tribe of the Wusun, supposed to be the remnant of an Aryan race, the original inhabitants of China. At the same time an English rival expedition starts on the same quest. The expeditions are facing the dangers not only of the desert but of the hostile Chinese Buddhist priests and of the leper colony with which Wusun is surrounded. By the time the desert is reached the American expedition consists of only one member, Captain Gray, and a Kirghiz guide. He comes upon the English expedition under Sir Lionel Hastings and his niece Mary. Being rivals they part company, each bent on reaching Wusun first. Sir Lionel is killed after he had set foot on its environs. Mary is taken captive by the Chinese and placed in charge of the Wusun. By sheer pluck Gray penetrates into the stronghold and puts up a gallant fight for Mary and the reader takes leave of them free but alone in the “infinity of Asia.”
