Excerpt from Plant-Breeding Being Five Lectures Upon the Amelioration of Domestic Plants I do not know of any explicit and sustained attempt to account for the evolution of all gar den forms, and I have therefore brought together in this volume the subject-matter of various lectures which I have been in the habit of giving before my students. The first and third lectures were newly elaborated the present summer for two addresses before the class in biology which came together at the University of Pennsylvania, under the auspices of the American Society for the Extension of Univer sity Teaching. The second lecture was first presented before the Massachusetts State Board of Agriculture, in Boston, December 1, 1891.
