 primary root first appeared. Near t'az end 

 of the primary root and the rootlets, very 

 minute hairs can be made out; these aie 

 called root-hairs. The tip of the root, as 

 in the bean does not contain these root hairs. 

 This root-cap serves as in the bean, to guide 

 the root in the soil.

 seeds ^fill not germinate im- 

 mediately when they are 

 taken out of the apple in the 

 fall. The teacher should put 

 a lot of apple seeds m a box 

 cover them with a little soil, 

 place the box where it will 

 not freeze or in a cellar. Dur- 

 ing the month of April these 

 seeds may be planted as were 

 the beans and peas. In the 

 course of a week the seeds 

 will germinate much as the 

 bean. The two seed-leaves 

 are pushed out of the soil and 

 expand. The root pushes 

 down into the soil. In a 

 short time successive leaves 

 are formed.
