CORRESPONDENCE. 
The Source of the Mississippi. The attention of geographers has 
recently been called frequently to this subject through the widely pub- 
lished claims of captain Willard Glazier. Many have questioned the 
justness of these claims, and the Minnesota Historical Society author- 
ized a careful survey under its auspices. The result was published by 
the state, as one of its volumes of "Collections," in which, written by 
Mr. J. V. Brower, the claims of Glazier were not admitted. This volume 
embraces a very full discussion of this question, with maps and other 
illustrations. 
Lately captain Glazier has revived his side of the discussion* in a 
finely illustrated book of over 500 pages. 
In this new volume he strongly insists on the verity of his discovery 
and the justness of his claim that lake Glazier is the true source of the
