8 Sioux City Academy of Science and Letters. 



John H. Charles, who has been so long connected with 

 the Academy and its predecessor, the Scientific Asso- 

 ciation. She, with her husband, Mr. John H. Charles, 

 who finished his work and left us a little more than a 

 year ago, has been a member of our association since 

 its organization in 1885. Her interest, sympathy and 

 help have been freely given to us through all the years 

 of our existence. 



The story of the long and useful life of Mr. Charles, 

 as given in this volume, was told by him while he was 

 here with us. The other articles in the book were writ- 

 ten by members of the Academy, and most of them have 

 been read at its meetings. We present them to the 

 public in the hope that all may find something of in- 

 terest and use among the various subjects discussed. 



Sioux City, 1906.
