CHAPTER I. 



INTRODUCTION. THE BEOAD BEAN PLANT. 



1. Seed Plants. In this book we shall study only the 

 higher plants, which produce flowers and seeds and are there- 

 fore called the Flowering Plants or Seed Plants, to distinguish 

 them from the lower plants which do not produce seeds 

 Ferns, Mosses, Fungi, Seaweeds, etc. 



Most Seed Plants agree in certain general features of form 

 and structure, though showing endless differences in details. 



2. Practical Work. Gtet all the seeds, plants, and other 

 materials mentioned in the directions for practical work and 

 carry out the directions faithfully, making observations and 

 experiments for yourself and keeping a careful record of 

 your work written in your own words and illustrated by 

 your own drawings from actual objects. 



3. Sketches Required. It is of the utmost importance 

 that, besides keeping a written record of all your observations 

 and experiments, you should make careful drawings of all 

 specimens you examine. Use a note-book of unruled paper 

 (not too thin) ; if you write your notes in the same book, 

 keep notes and sketches on separate pages ; make your 

 sketches large (natural size or, in most cases, enlarged) and 

 clear (no shading, no superfluous or meaningless marks or 

 lines, and no "inking-in" afterwards). Measure the spe- 

 cimens you are going to draw, record the measurements, 

 and if enlargement is necessary in order to show details 

 clearly, draw to a definite scale and note how many times
