The title of this short essay is not the outcome of any foible on my part towards a chance euphonious coupling of two not ill-suited concepts. The phrase indeed, being short, simple, and succinct, should convey accurately the motive and method which have together dictated the form of this study. Restricted as it had to be, the field of research is still wide, and the flowers that grow therein are not only time-worn, but their types show many and often baffling variations. Among these a choice had to be made, and I have made it, mainly in each case for the contrastive effect aimed at and displayed in the symbols of Then and Now.
