Part II treats of the history of the topography. The Baraboo region 
is treated as an example of the results of processes of rock formation 
of rain and river erosion, and of glaciation. The work is not so much a 
description of the region as a general treatise on a few of the processes 
involved in the evolution of land surfaces. Erosion is treated in an or- 
iginal manner and this portion of the work should prove of value to 
teachers indicating the true method of beginning any science. It treats 
of rivers from their origin and traces their development, thereby depart- 
ing from the usual text-book method of discussing and classifying com- 
pleted geographic forms. The portion devoted to the glacial period is 
probably the best treatment of the subject accessible to those who are 
not geologists and the Baraboo region affords an admirable field for the 
discussion of glacial phenomena. 
The form of the paper is such as to render its paramount value edu- 
cational rather than geological. The most evident original work is con- 
tained in a masterly treatment of simple and familiar processes rather 
than in the solution of the Devil's lake problems. Yet these problems 
are important in themselves and the paper might have gained m useful- 
ness as a work of geology without a lessening of its educational value bv 
placing more emphasis on the local phenomena themselves, by a less 
elementary treatment, particularly in the portion on rock formation.
