THE THREE CLASSES. 9 



some carefully, and we shall soon learn which must 

 belong to the Second Class. Take the Bulb of a 

 Tulip, Lily, or (if you prefer it) an Onion ; cut it 

 down the centre, and you will see that it is formed of 

 a succession of layers, folded closely round, or in loose, 

 fleshy scales, outside. These are formed of Stem and 

 Leaves, and are true Bulbs : always belonging to the 

 Second Class. PI. I. B 6. 



Some Plants of the First Class have BULBOUS 

 BOOTS, formed of Stem, so solid that you cannot 

 distinguish the layers of which it is composed. These 

 Boots are called CORMS. PI. I. A 5. 



We call them Boots, but the real Boots of all Corms 

 and Bulbs, are the fibres which grow out of the lower 

 part of them. 



TRUE BULBS are formed of Leaf-buds, which you 

 will find growing on the Stems of some Lilies, above 

 each Leaf. Set some of these little round buds in a 

 pot of earth, and watch their gradual growth into 

 perfectly formed Bulbs, which Bulbs will in time 

 reward you with Flowers. 



You now know the most important distinctions 

 between the two First Classes. I hope you have been 

 so interested in examining and comparing, as to be 

 able to tell already, in which Class to place a
