 work. It is therefore expedient to have at all 

 times a due place in education for that subject, 

 or group of subjects, in which, at the time, the

 are going forward. The spirit of search is caught 

 from teachers who are themselves searching ; not 

 simply by artificially reproducing the methods of 

 search in provinces of knowledge which are en- 

 joying the peace of unchallenged acceptance. 



The greatest educational service which the 

 scientific movement has rendered is in emphasising 

 certain principles which should guide the teacher 

 in his methods of work. These are that the 

 physical side of education is basal to mental and 

 moral training ; that child-nature must be studied 

 in order that all instruction may be adapted to 

 the learner's stage in mental development ; that 

 sense-perception and practical work should have 

 a place, though not an exaggerated place, in all
