 that they expand in the li-lit and .iii— which is the proper phice for leaves, as 

 the dark and damp soil is for th.e root.

 of it, we no more know, than we know why newly-hatched 

 ducklinfrs take to tiie water at ince, while chickens avoid

j^o. Notice how early the seed- 

 ling' plant is complete, that is, 

 hecomes a real ve<,'etal>le, with 

 nil its parts, small as the whole 

 thin<jf is (Fig 21). For it al- 

 ready possesses a i-oot, to connect 

 it with the ground and draw up 

 what it needs from that ; a stem 

 to elevate the foliage into the 

 light and air ; and leaves, to take 

 in what it gets directly from the 

 air, and to digest the whole in the light (as explained in the last section, Par. 7). 

 That is, it already has all the Organs of Vegetation (Par. 1), all that any plant 

 has before blossoming, so that the little seedling can now take care of itself, and 

 live — just as any larger plant lives — upon the soil and the air. And all it has 

 to do in order to become a full-grown plant, like Fig. 4, is to increase the size of 

 its organs, and to produce more of them ; namely, more stem with more leaves 

 above, and more roots below. We have only to watch our seedling plantlets a 

 Week or two longer, and we shall see how this is done.
