GUIDE IN REVIEW 451 



upon the locality in which it is taught, the part whose nature is 

 determined by what plants are of chief local importance and interest. 

 This is a part which is of primary importance, but its nature and con- 

 tent must be determined by the individual teacher. It cannot be 

 dealt with satisfactorily in a basic text. 



Thus it will be noted that Table I includes no names at all of kinds 

 of plants. Table II names only those which are essential to a com- 

 prehension of the evolutionary sequence, while Table III names only 

 a few of the chief groups, and a few of the most famUiar families of seed 

 plants. Important economic plants, and many of the important 

 practices in plant culture, are not listed at all, solely because the study 

 of such should be locally determined. Trees are listed as one entry 

 but those " trees and flowers which every boy and girl should know " 

 are not listed, for the list depends on the locality. 



The danger that some students may use these tables simply as a 

 guide to " cramming " is recognized, yet it is believed that this danger 

 is overweighed by the service such tables may render to the more 

 serious student. It is also recognized that this danger is no danger 

 at all in the presence of a skillful teacher, one able readily to unmask 

 sham knowledge.
