this series belongs _The Ball of Crystal_ (1903) with which our selections begin. Style and narrative art have matured; we have to do no longer with mere anecdote, as in the _Tales of the Councillor's Girls_, but with a more concentrated plot; the character of the heroine, which is symbolized by the title, is subjected to a more profound psychological diagnosis; but we are still taken with the same purity of heart as in the earlier narratives, and the quintessence of this book, as indeed of the entire literary personality of the authoress, may be found in the final words of the _Tales of the Councillor's Girls_: "The kind, the imperturbable, who with gentle readiness take good or evil as it comes--they are the real heroes, not those who face life bristling like a porcupine. The only thing which can give our hearts peace and happiness on earth is good will toward men." Clara Viebig is a less gentle nature. She is a poetess not so much of the heart and soul as of the impulsive temperament and the strong will. She has not passed through any vacillating development, nor has naturalism been for her as for Helene Böhlau a mere preparatory school or transition stage; on the contrary, in all her work she has consistently remained a disciple of Zola and has not shrunk from any of the brutalities of his method. There is not much to tell about the personal life of this authoress. Born at Treves on the Moselle in 1860 as the daughter of an official in the civil service, she was taken when quite young to Düsseldorf on the Rhine, but passed a part of her youth in eastern Germany, in Posen, the birthplace of her parents. After her father's death she came to Berlin to study music; here she became a writer, and now she is living as the wife of her publisher in the suburb of Zehlendorf. Her spiritual experiences are perhaps most clearly set forth in the novel _Long Live Art_ (1899). The passionate struggles of a young authoress for literary success lead after many disappointed hopes and many disillusionments to the attainment of genuine good fortune in art and in domestic life as well. On her native heath the despairing woman is cured of her despair--this typifies all the work of Clara Viebig, which reveals itself as pure _Heimatkunst_ in advance of the time when this label gained currency. To be sure, it is a triple home that Clara Viebig can call her own, the Rhine country, eastern Germany, and Berlin. As might be expected, the memories of childhood left the most lasting effect upon her. The Eifel, that bleak plateau between the Moselle and the Rhine, with its broad melancholy heaths and bald craters of extinct volcanoes, with its dark lakes and lonely forests, is the district with which she is most familiar. The hard-headed, moody, quick-tempered peasants, whose stubbornness befits the volcanic origin of their mountains, appear in her first collection of short stories, _Children of the Eifel_ (1897). In the Eifel is
