THE SEED. 143 



in which to write the results of study. Such a note- 

 book is easily made by twice folding enough sheet- 

 paper to allow a page to each kind of seed you have 

 planted. Write the name of a kind, as pea, oat, etc., 

 on each successive page, till all are inserted. 



When your seeds have soaked for a day or two 

 in the wet earth, take a bean from the box and com- 

 pare it with one that has not been planted. 



How has it changed in appearance ? 



Cut it in two and see whether, like a piece of 

 chalk, it looks alike outside and inside, or whether 

 the parts are unlike. 



Has it a skin or shell that you can loosen ? 



Take a second bean from the box, cut carefully 

 around it, and try to peel off the outer part. 



FIG. 251. 



Body. 



SEED-COAT, OR INTEG'UMENT. The skin or shell 

 around the outside of a seed. 



BODY, KERNEL, OR NU'CLEUS. The substance 

 within the seed-coat. 



Compare your specimen with Fig. 251. 



Can you separate the seed-coat from the body of 

 the bean as it is seen to be separated in the picture ? 



Now take a pea from your box and see if it is 

 made up of parts.
