International Language Study. — An in- 

 teresting and comparatively new scheme for 

 the study of foreign languages is described 

 by E. H. Magill, ex-president of Swarthraore 

 College, in a recent issue of The Kindergarten 

 Magazine. " How these foreign languages 

 can best be taught in our schools and colleges 

 is a question which has received much atten- 

 tion at the hands of experienced educators 

 of this generation." Some have contended 

 that no attempt should be made to teach the 

 student to converse or write in the foreign 

 language, but that he should simply learn 

 enough of grammatical form to enable him, 

 when he has obtained a vocabulary, to read 

 the written language easily. In fact, this 

 opinion has been very generally held by edu- 

 cators. The method of instruction about to 

 be described, however, seems in a fair way 

 to change this feeling into one favoring a' 

 more perfect mastery of the language. " It 

 is now about two years since M. Mieille, a 

 professor in the Lycee of Tarbes, Hautes- 

 Pyrenees, while in England, devised a method 

 of international correspondence between stu- 



dents and teachers in France and England, 

 which has been warmly received by educators 

 and students in those two countries, and sev- 

 eral thousands on either side of the channel 

 are now entered upon the lists and mutually 

 rendering each other great aid in becoming 

 familiar with their respective languages. . . . 

 The method of procedure may be simply de- 

 scribed thus : Let those schools, colleges, or 

 individuals who wish to begin this system 

 send the names, ages, and addresses of those 

 who wish to correspond to the following well- 

 known firms in Paris : For young students, 

 send to MM. Aimand Colin et Cie., No. 5 rue 

 de Mezieres, Paris, and for older students, 

 teachers, or other mature persons, address 

 Libraire Hachette, 79 Boulevard Saint-Ger- 

 main, Paris. These firms will give prompt 

 attention to such requests, assigning to each 

 person whose name, etc., is sent, a suitable 

 correspondent ; and these French correspond- 

 ents write the first letter, in French, to their 

 American friends, who on receiving the 

 letters promptly reply in English. After 

 these first letters the next letter from France
