CHAPTER XIV 



THE RACIAL INFLUENCE OF INDUSTRIAL 

 DEVELOPMENT. 



" A few good and healthy men, rather than a multitude of diseased 

 rogues; and a little real milk and wine rather than much chalk and 

 petroleum; but the gist of the whole business is, that the men, and 

 their property, must both be produced together not one to the loss of 

 the other. Property must not be created in lands desolate by exile of 

 their people, nor multiplied and depraved humanity, in lands barren 

 of bread." Ruskin, The Queen of the Air. 



IT is obvious that many of the most potent of the factors 

 which influence the inherited qualities of man are the result of the 

 great industrial development which has taken place during the 

 past century. To give an adequate account of the complex and 

 indirect ways in which the growth of modern industry has affected 

 the development of the race is at present an impossible task. 

 Even most of the simpler problems cannot be solved with the 

 data at present available, and where the immediate result of 

 certain forces seems fairly obvious there are commonly secondary 

 and more indirect effects to be considered which stand in various 

 relations with, and sometimes in direct antagonism to, the 

 primary ones. 



The magnitude and rapidity of the changes which industrial 

 development has effected in the institutions of mankind tend to 

 divert attention from the more obscure biological problems with 

 which they are associated. It will perhaps be useful to formulate 

 some of these problems, although we may not be able to contrib- 

 ute much to their solution. 



Among the more immediate effects of industrial development 

 are (i) the increase of population in many countries which has 

 been rendered possible by the creation of additional occupations 

 and the expansion of trade; (2) the growth and multiplication of
