There is no doubt that the thriving condition of Switzerland is chiefly due to three causes--the thriftiness of the people, their natural ability, and perhaps, more than all, the excellence of the educational system. On this last point much has been written by the late Matthew Arnold and Sir F. O. Adams, and to their works the reader must be referred for details. We may here mention, however, that besides the primary, secondary, and high schools, which are to be found in every canton, Switzerland stands out conspicuously by the number and excellence of its technical and trade schools. The great Polytechnikum of Zurich is the pride of the country, and Basel, Zurich, Bern, and Geneva have universities, and Neuchâtel and Lausanne academies.[108] Primary education is entirely free, and to it the greater share of the education vote is assigned--in 1887, nearly seventeen and a half million francs out of a total of twenty-six and a half millions given to education. Attendance at school is compulsory, and there were in 1887, 467,597 children attending the primary schools. [Illustration: PORTRAIT OF GOTFRIED KELLER, THE POET. (_After a Photograph._)] Of men of intellect, of talent, of artistic, scientific, or literary skill, Switzerland has produced many, and has sheltered many more. The numerous academical institutions, literary, scientific, and musical societies, draw together large numbers of superior intellects. Amongst the numberless men of science now or lately living may be mentioned Agassiz, Desor, De la Rive, Heer, Merian, Studer, and Dr. Ferdinand Keller, the discoverer of the lake dwellings. In literature we have Viet, Marc Monnier, Zschokke, as well as Leuthold, Gotfried Keller, and Ferdinand Meyer. Keller has a reputation more than European; he has been called the German Shakespeare. He belongs to Zurich. The occasion of his seventieth birthday (on July, 1889), brought a remarkable demonstration. The Assembly voted him an address, and enthusiastic congratulations poured in upon him from all quarters. From Germany Von Moltke himself headed the list of admiring friends who sent messages. Keller is acknowledged to be the greatest living German poet. Amongst painters are Calaine, Diday, Girardet, Gleyre, Vautier, and Böcklin, whom the Germans consider one of their greatest living painters; and of sculptors, there are Vela and Lanz. Gustave Weber and Joachim Raff are well-known musical composers, with whom we must name Baumgartner, who has raised Keller's "Oh, mein Heimatland," into the position of a second national anthem.
