Leitz Petrographical Microscopes 

NEW MODELS-WITH ENLARGED FIELD OF VIEW 




Microscope "S.M." with synchronic 
rotation of the nicols 



These microscopes have been developed 
on the basis of latest suggestions from 
petrographists. Their novel and modern 
design will prove a great aid in petro- 
graphical studies. 

Every leading petrographist knows the 
superior optical and mechanical qualities 
of Leitz microscopes and we therefore 
are fully safe if we refrain from enumer- 
ating the many features. 

The variety of models we offer afford 
a suitable equipment for every specific 
requirement. 

The complete assortment of our petro- 
graphical accessories will interest those 
who desire to add to their present 
equipment. 



Some of the prominent features of the new model 
microscopes are: 

i. Improved Objective Clutch Changer which guarantees the objective to be 
permanently centered. 

2 Anastigmatic Tube Analyzer which permits a most crisp definition. 

3. Special Illuminating Apparatus, whereby a wider range of application is 
afforded. 

4. Enlarged Microscope Tube which accommodates eyepieces of wide diameter, 
whereby the field of view is increased 50% over other types of instruments.

has resulted in the collection and organization of 
the material most suitable for the purpose 

The book contain short magazine articles 
and materials from Can dian, Mexican, and 
United States government publications. The 
selection of the material has been governed by 
the concept that there is a dire t relation be 
tween the environment and the economic activ 
ities of the region The author aims to survey 
the different section of the country from the 
viewpoint of industrial opportunity

The Geography of Illinois 

By DOUGLAS C. RIDGLEY 

Professor of Geography in the Illinois State Normal University 

The author's aim is to provide an authoritative study of the state, presenting in 
compact form the wide range of physical influences which make up the geographic 
environment in which men live. 

The natural features and natural resources of the state are treated in some detail . 
The great occupations of mankind — agriculture, mining, manufacturing, trans- 
portation, and trade — are discussed with sufficient fulness to give an adequate 
idea of their development and present importance within the state. The popula- 
tion census of 1920 for Illinois is treated in a final chapter. The book is designed 
to be of interest to the busy citizen who wishes to know his state as a unit in its 
present-day activities; to teachers and pupils who would know Illinois well enough 
to interpret other regions in comparison with the home state; to all who wish to 
learn the reasons for the high rank of Illinois in many lines of human endeavor. 

Abounds with draw'ngs, maps, illustrations, and colored insert maps
