3. The rustic and the urbanite not only show certain fundamental differences in personality, but the variations found in the city far exceed the country, and the rate at which new types are constantly being created in the city far exceeds that of the country. The rural man still is to a great extent the product of the nature which surrounds him, while the urbanite has become a part of the machine with which he works, and has developed as many different species as there are techniques to which he is devoted. The attitudes, the sentiments, the life organization of the city man are as different from the country man as those of the civilized man are from the primitive. As the city extends its influence over the country the rural man is also being remade, and ultimately the differences between the two may become extinguished.

THE STUDY OF THE CITY Attempts to understand the city and city life have resulted in two types of studies. On the one hand there are the investigations into special phases of the subject, and on the other are a number of systematic, generally co-operative, scientific approaches to the city as a whole. The increased attention which the city has been receiving at the hands of various types of experts has brought into existence a number of organizations and institutions which regularly occupy themselves with the collection of information relating to the city. This has given rise to a number of technical journals which are of great importance to the student of the city. 1. There are available at the present time a number of fairly exhaustive systematic studies of various cities. In most instances they represent the combined efforts of many students, extending over a period of years, to explore the realms of urban life in diverse parts of the world, generally with a definite objective in view. Only a few of such studies have been listed under this category. Booth, Charles. _Life and Labor of the People of London_ (16 vols.; London, 1892).
