HORTICULTURE AS A PROFESSION! 



Tece advancement of civilization is 

 marked by certain well-defined epochs. 

 There are the old stone age and the new 

 stone age, the age of bronze, the age of 

 steam, the age of electricity. More recently 

 events have moved forward with prodigious 

 acceleration. We were no sooner begin- 

 ning to think of the present as the age of 

 the automobile, than the airplane rose above 

 the horizon, and the age of flight was 

 ushered in. The discovery of the telephone, 

 the wireless telegraph and the wireless tele- 

 phone would either of them have been of 

 sufficient moment to give a name to a new 

 epoch had they only been separated by 

 sufficiently long intervals. 



So it has been with the emancipation of 

 woman. So-called "female seminaries" 

 were followed shortly by women's colleges, 

 and by coeducation in the liberal arts col- 

 leges of our universities. Finally the pro- 

 fessional schools opened wide their doors, 

 and we became accustomed to women law- 

 yers, doctors, and engineers. The great 

 world war disclosed the fact that there was 

 one occupation essentially masculine, but 

 the departure to France of some two mil- 

 lion or more of our male population as 

 fighters spelled Opportunity with a capital 

 for the daughters of men, and we have 

 now become familiar with women muni-

 women elevator "boys," and women mes- 

 senger "boys." 



Certainly we are living in an age of rapid
