2 NATURE TEACHING 



which the seed was obtained, and that if we wish to grow 

 bean plants we must sow bean seeds, and acorns if we 

 wish to raise oaks. 



We know, also, that although a dry seed is to all 

 appearances a mere dead thing, it soon springs into life, 

 or germinates, if we place it in a warm place and give it 

 a supply of moisture. 



Moreover, we are aware that even dry seeds cannot 

 be stored for a very long time without gradually dying, 

 for the farmer or gardener who is anxious to raise good, 

 full crops is careful to secure good seed, obtained usually 

 from the crop of the season before, and does not sow 

 any old seed which may be to hand. 



This general knowledge is most valuable, inasmuch 

 as it is the outcome of the practical or experimental 

 work of ourselves, and of those before us who have 

 handed down their results. It is not, however, enough 

 in itself, and we should endeavour to understand how, 

 and as far as possible why, the events follow each other 

 with such certainty. 



A correct knowledge of the seed and of the conditions 

 for its germination, and for the successful growth of the 

 seedling and plant, touches the very foundation of that 

 sound agricultural practice so essential to success at the 

 present time. 



The Parts of a Seed. 



In order to distinguish the various parts of a seed, 

 it is best to examine one which has begun to grow, or, 

 as is more commonly said, to germinate, for in this 

 condition the parts can be more easily separated and
