SCIENCES IN THE HI OH SCHOOL 163 



adjustment of the microscope, do not belong below the second year of 

 the high school. And correlated with the botany may appropriately 

 be placed budding, grafting, spraying and pruning in a more rational 

 form and demanding a higher grade of skill. School gardening, exer- 

 cising, as the work does, the larger body muscles, is appropriate to the 

 primary grades. Nature study may be defined as the most appropriate 

 muscle culture known to the schools in that it automatically adjusts 

 itself to the stage of development of the pupil. Until some one defines 

 more definitely than has yet been done the character of animal hus- 

 bandry best suited to the schools that subject may go anywhere in the 

 course. "When the need and the opportunity for the drawing of correct 

 animal conformation are appreciated, it will be given an advanced posi- 

 tion. Exercises in advanced physics demand delicate adjustments 

 appropriate to the last year of the high school course, which position 

 also agrees with the mathematical requirements of the subject. Accu- 

 rate use of dissecting instruments, the fine balance, fragile glassware 

 and c.p. reagents, and the making of a pure culture and keeping it 

 pure, demand muscular skill not to be found below the third year of the 

 high school course. 



Influenced by this factor, the high school sciences will find their 

 places, and the sequence of the different phases of agriculture that are 

 naturally correlated with them will, by the same process, have their 

 positions determined.
