Excerpt from A Laboratory Course in Plant Physiology: Especially as a Basis for Ecology If the present book is found to have any merit in its particular field, it will consist chiefly in its practicability. With but few and clearly indicated exceptions, everything recommended in it has been repeatedly tested and found effective both by my students and myself. The book is the resultant of six years of effort and experiment directed to this end with classes of from eight to twelve students. The illustrations of the experiments are in every case from photographs of experiments in successful operation. Such pictures, while inferior in clearness of detail and perhaps in artistic effect to good drawings, have at least this conspicuous merit, that they may be accepted and followed with perfect confidence. In developing the course and the experiments herein recommended, I have tried to utilize, and, naturally, to improve upon, the best work done by others in the same lines. Little account is taken in these pages of the exact appliances and methods with which the classical work of plant physiology has been done, for the investigation phases of the subject lie without the scope of this work, and they are, moreover, summarized admirably in Pfeffer's great Handbook. But all phases of plant physiology utilizable for purposes of general education are meant to be included.
