This thorough and interesting geographical 

 study of the best-known feature of the Illi- 

 nois Valley has been prepared for the benefit 

 of those who are interested in knowing more 

 about the region than can be gathered by 

 personal observation in a few hours or a few 

 days spent in the park. The physical geog- 

 raphy of the park and its surroundings has 

 a number of features, such as the beautiful 

 little canyons, which are unusual in this part 

 of the country. Part I is given up to the 

 geography of the park, its surface features 

 and their origin, and the exploration, settle- 

 ment, and development of the region; Part 

 II, to the geology of the park; and Part III, 

 to its botany.

 animal kingdom present to us a picture of such infinite variety? .... And why, running through the diversities, 

 are there so many resemblances? .... The purpose of Professor Thompson's book is to e,xplain the 'must be' of
