Les Trois Mousquetaires. By Alexandre Dumas. Edited by Prof. 



F. C. Sumichrast. 12°, pp. 289. Ginn & Co., Boston. (Price 



80 cents.) 

 The present edition of this justly celebrated novel of Dumas is an 

 attempt to offer a condensation of the story, giving the brilliant descrip- 

 tions and characteristic dialogue and the captivating rush of advent- 

 ures untouched. The objectionable passages are excised, and the vol- 

 ume brought v^^ithin such limits of length that it may be conveniently 

 used as a text-book. The notes are divided into two parts. The first 

 consists of explanations of the difficult passages and allusions, and the 

 second biographical and geographical notices of the principal historical 

 personages and places mentioned in the narrative.
