130 MANUAt OF NATURE STUDY. 



protected from mice? (Long pendant stalks). 



After cherries have fallen upon the ground the 

 earwigs and caterpillars devour them. How are 

 they protected against the attacks of these animals 

 when growing upon the tree ? (Suspended upon 

 stalks.) Fruits without spines or protective bris- 

 tles, as apples, cherries, peaches, etc., when unripe, 

 are bitter and therefore not sought by animals. 

 When ripe these fruits are much sought by 

 birds and other animals which carry them away, 

 thus helping in the dispersal of the seeds. 



6. Study how embryo gets out of coat. Plant 

 seeds of different kinds such as corn, beans, peas, 

 acorns, flax, etc., in moist sand or saw-dust, in flower 

 pots, cigar-box or glass tumblers, being careful to 

 cover each vessel with a glass slide or piece of oil paper 

 to prevent evaporation. Thick blotting paper, moist- 

 ened and placed on a pane of glass, furnishes an 

 excellent ground work for the planting of seeds. 

 Sheet cotton would also answer the purpose to a 

 very great advantage. After the seeds have been 

 planted the same should be covered with another 

 sheet of moist blotting paper and then set away in 

 a warm place of the temperature required for grow, 

 ing seeds. The growth of these seeds may be 

 observed at every stage. Let the children see where 

 the coat in each case bursts. In the case of the corn, 

 which end of the plantlet bursts out of the coat first ?
