GEOLOGY IN EDUCATION i 



What would be the result if those who 

 are interested in education could come de 

 novo to the question of the content of an 

 ideal curriculum of study 1 It probably is 

 safe to say that one of the results would be 

 a shock to those whose opinions on this mat- 

 ter have been shaped by the prejudices 

 which accompany our inheritance. That 

 evolution is a slow process is illustrated 

 nowhere better than in educational circles. 



Let it be assumed that the consideration 

 of what is most valuable in education could 

 be approached by a jury which has an in- 

 telligent grasp of all subjects, as now un- 

 derstood, and of these subjects in their 

 proper relations. Let it be assumed fur- 

 ther that the jury is unprejudiced by tra- 

 dition or by pronounced personal bents in 

 favor of or against individual subjects. 

 What conclusions would they reach? To 

 this question there is of course no cate- 

 gorical answer. Wisdom would decree that 

 there is no one model curriculum — that 

 there should be various types of curricula, 

 each susceptible of adaptation to individ- 

 ual needs. 



The classes of subjects whose claims 

 would need to be considered in such a 

 study as that here suggested fall into sev- 

 eral general classes. It goes without say- 

 ing that their values would be differently 

 gauged by different men, and that their 

 values are different for different men. 



Without presuming to make an exliaust- 

 ive classification, it is clear that one great
