EVOLUTION OF PREHISTORIC CULTURES 



NATURAL HISTORY OF MAN 



Continuing west we pass into the Southwest Pavilion, given over to a 

 demonstration of the chronological development of the principal human 



Cave Man arts and industries initiated before the days of written 

 and the history, the era of the Cave Man and the Lake Dweller. 



Lake Dweller The sect i on f the hall to the left, or south of the center 

 aisle, is devoted to the Old World, while the section to the right is given 

 to the New World. There arc four rows of table cases in the hall and 

 eaeh row or tier constitutes a unit, or part of a unit, and should be 

 examined in order, beginning next the entrance and going towards the 

 opposite west wall. 



The first table case on the left gives a key exhibit for the Old World. 

 Here is shown the order of development of several of the most common 

 TheEvolu- tools, weapons, utensils and ornaments, ranging, as in 

 tion of the case of the ax, from crude " eoliths " many thousands of 



Cultures years old up to the metallic forms more or less like those 



in use at the present time. The various stages of improvements are 

 arranged in levels and new forms of tools, with correspondingly new arts 

 and industries, will be seen to make their appearance in each of the 

 successive levels, as the case is viewed from front to back, beginning at 

 the left end. The succeeding cases in this row take up all the different 

 levels here indicated, treating each one as fully as the available archae- 

 ological material permits. 



The adjoining row of cases on the left, next the windows, gives the 

 stratigraphically determined order of cultural development for several 

 separate localities in the Old World, such as France, the Baltic region, 

 Switzerland and Egypt. Here are shown the fragmentary, but strictly 

 scientific, details of the story told in simplified form in the first row of cases. 



The northern half of the hall, and the wall cases devoted to America, 

 will w r hen completed be arranged on the same general plan. 



The circular, or tower room, in the southwest corner will ultimately 

 house an exhibit for the racial history of man. In the left w T all case at 

 The Evolu- the entrance to this room is an exhibit showing the import- 

 tion of ant face and head differences in modern man and also the 



Races instruments and methods for measuring faces and heads. 



On the opposite wall is a similar demonstration for body measurements. 

 The adjoining cases in the tower contain the skulls and bones (casts) 

 of fossil men, the ancestors of modern man. There are also exhibits 

 showing the hair, teeth, etc., of different existing races.
