same type of enthusiasm for it as the physician has tor his 

 report of successful methods of treating a difficult case. 



Our enthusiasm for the course is tempered by the knowl- 

 edge that many a wise head will be shaken in doubtful nega- 

 tion. The course itself probably will not be accepted in some 

 colleges as suitable preparation for the type of work which 

 these institutions administer. The knowledge that it will 

 thus knock in vain at certain academic doors moves us, to 

 be quite frank, only in the direction of a firmer belief that 

 the course is needed. So we hold to our enthusiasm, confident 

 that many a co-worker in the science of teaching will take 

 from the book, not alone material about air and water, but 

 also new encouragement to fit air and water and all nature 

 to human needs and to students' needs.
