Ii6 BOTANY. 



pies for the purpose. Plant two or three dozens of each 

 sort, one inch deep, in a box of soil or sawdust, which 

 must be kept warm and moist. Put the different kinds in 

 rows by themselves, and mark each row, so that, when you 

 want any particular one, you can get it without mistake. 



When your seeds have soaked for a day or two in the 

 wet earth, take a bean from the box and compare 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. 



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. 363. 



Body. 



FIG. 363. 



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. 



Has it a seed-coat ? Is there a kernel or body within 

 the seed-coat ? 



Try a pumpkin-seed. Compare the coat of a pump- 

 kin-seed with that of the pea or bean.
