generally speaking, to be true that his mind 

 has worked chiefly intensively. From that 

 time on I suppose it to be true that the mind 

 should work chiefly extensively. The point 

 at which one method of thinking passes 

 over into the other would be hard to trace. 

 One can do extensive thinking in school and 

 must do intensive work after assuming the 

 work of life. None the less, generally 

 speaking, I believe that the training of 

 young manhood looks to the extension of 

 thought in maturer life. You are not pri- 

 marily going on to get facts out of books 

 and out of the laboratory and out of the 

 experience of others into your mind. You 

 are to begin to take the facts which that 

 mind has digested and to work them out 

 into useful forms and into productive serv- 

 ice. You have been perhaps the benefi- 

 ciaries hitherto of the things which have 

 been created and of the thoughts which 

 others have worked out in the crucible of 

 their own mental processes. You are now 

 to become in a sense creators and to think 

 both for yourselves and others. You have 

 been one may say absorbers ; you are to be- 

 come producers. Your value as men de- 

 pends on what the product shall be. 



The country is not so greatly concerned, 

 I venture to believe, with the amount that 

 a man knows as it is with the use he makes 

 of what he knows. It does not want the 

 man who, while his body may live, still 

 keeps his mind in a mental churchyard. 

 One of the great phrases of the Old Testa- 

 ment says : ' ' Thou hast taken me and Thou 

 hast set me in a large place ; ' ' and what the 

 world needs is men who can think in great 

 areas. It is necessary but it is not sufficient 

 to get the facts. One who would do a man's 

 job in the world must through those facts 

 serve his fellows. 



Think, if you please, what the symmetry 

 of life should be. It should not be narrow ; 

 it should not be crooked. It should be 



straight and square. It should be high, to 

 keep out of the dust and mire. It should 

 be broad that it may rest securely. It 

 should be deep based on the eternal verities. 

 It must not be low, for living things grow 

 upward into the light. I would have you 

 question all your life long whether this or 

 that or the other form of alleged truth 

 which is presented to you be so or not. If 

 it is found not to be the truth I would have 

 you reject it without regret and without 

 fear of inconsistency, for there is some 

 force in the statement that consistency is 

 the virtue of weak minds. Truth is pro- 

 gressively revealed and one must readjust 

 himself in thought and action to the greater 

 knowledge of truth that we ought contin- 

 ually to gain. The man who at fifty 

 thinks as he thought at thirty has mentally 

 ceased to grow. If one's mind is open to 

 the light whencesoe'er it may fall, if one's 

 steps are guided by that light whither- 

 soe'er it may lead, there is little to fear 

 either as to treading the path safely or as 

 to the place in the world to which it shall 

 conduct one.

 " The mid-year finds the mineral industries 

 of the United States generally prosperous and 

 enjoying a revival of active development." 

 With this statement the director of the United 

 States Geological Survey opens an official re- 

 view of mining conditions as reported to him 

 by the government geologists and statisticians 

 working on this subject. " This revival is par- 

 ticularly true of some of the metals for which 

 increased demands have been noted during the 

 past six months. This country has been first 

 thrown upon its own resources for mineral 

 products required and, next, given the oppor- 

 tunity to supply the needs of foreign countries 

 who have offered us their trade. Comparative 

 freedom from foreign competition and, in some 

 important cases, increase of foreign markets
