 will adopt them into the curricula of the 

 strictly classical colleges. 



However, science has a large pedagogic 

 value, too, when it is properly presented, and 

 we are learning slowly how this presentation

 ture is only partly a science (and partly em- 

 piricism and partly art), still we try usually to 

 teach it from the scientific side. This is be- 

 cause the science of horticulture has greater 

 " pedagogic value " than the empirical art 

 has. 



Now, among the various branches of horti- 

 cultural science none has greater " pedagogic 

 value " than systematic pomology. One rea-
