PHYSICAL GEOGRAPHY. 



lists will be found in an appendix to this volume, each under 

 the name of its author. From these and other data Mr. W. H. 

 Morley has constructed for this report the following table, 

 showing the elevation of some of the principal points in the 

 State, and another on a following page showing the slope of 

 the principal rivers. From the same data, he has also com- 

 piled material for the accompanying diagrams which show 

 five profiles of the surface of the State, on lines running from 

 east to west across it. These tables and diagrams together 

 will alone serve to give a good general idea of the topo- 

 graphy of Iowa, but for more information concerning its 

 details the reader is referred to the tables in the appendix in 

 addition to the following descriptions :
