THINGS GREEN AND FAIR 17 



Yes ; if only the rule held good throughout. Strange 

 to say, it does not. 



In that hazy borderland, between the two Kingdoms, 

 the test breaks down. Animals and plants, living there, 

 are very tiny, very simple in make, very much alike, 

 and very puzzling. Some of these minute animals will 

 fix themselves in one spot, and stay there, and behave 

 for all the world like plants. And some of these minute 

 plants will actually swim about in search of food, going 

 from one place to another, and behaving for all the 

 world like animals. 



So it is not surprising that learned men should have 

 made a few mistakes, in trying to settle which was which ; 

 or that certain learned men do not believe that any clear 

 line at all can be drawn between the two. 



Ill THE PARTS or A PLANT 



We will go now for a little stroll around the garden, 

 and find out what there is to be seen. If you cannot 

 go into a real garden, you must picture one in your mind. 



The first thing to be noticed is this that plants, in 

 growing, follow a regular plan. 



They do not come up anyhow, in a chance fashion, 

 so that nobody can tell what to expect. Unlike as one 

 plant is from another, still they are more or less built 

 after one general scheme. 



Certain parts are found in the greater number. And 

 if one asks, " Which parts are those that go to make up 

 a full plant ? " the answer will perhaps be, " Oh, that 

 is easy enough. There are roots and stems, branches 

 and leaves, flowers and fruits and seeds, and heaps 

 more."
