SPECIALIZATION IN EDUCATION.* 

 The past few years have witnessed pro- 

 found changes in the industrial conditions 

 of our people, changes which, to many, are 

 of deep portent. The concentration of 

 wealth, the centralization of power, the de- 

 velopment of monopolies, all have seemed 

 to menace the equilibrium of our nation, 

 and dire have been the prophecies of evil. 

 But, with all these changes, with oil trusts 

 and steel trusts and other trusts innumer- 

 able, have also come national supremacy 

 in commei-ce, the creation of vast wealth, 

 and an advancement in well-being. The 

 industrial world, like the rest of the great 

 world of nature, is never at rest. Every 

 new invention of labor-saving machinery, 

 every new discovery of importance, brings 

 unhappiness and misery to some, but in- 

 creased happiness and pleasure to many 

 others. So too, who sliall doubt but that 

 the present monopolistic movements, the 

 trusts and the mergers, when we shall have 

 learned to guard that which is good and 

 prevent that which is bad, will residt in 

 greater benefits to mankind and a higher 

 civilization ? To check the greed of trusts 

 there are labor unions, to check the law- 

 lessness of labor unions there will be con- 

 sumers' unions, and over all there wiU be 

 .social laws to harmonize dissonance. Man,
