APPENDIX II 145 



Morning Glory (soaked over night) needs about three 

 days. 



Onion (soaked over night) needs from eight to ten days. 



The caulicle is the first organ to protrude beyond the 

 seed-coats in almost all ordinary seeds. A detailed con- 

 sultation of Lubbock's Seedlings will show this. 



IV, V. It is well to plant in loose soil (or sawdust) about 

 three lots of well-soaked Beans and Peas. The first lot should 

 be planted about three weeks before they are needed ; the 

 second lot a week later ; the third lot about a week before 

 they are needed. In regard to such matters as having seed- 

 lings in good condition, i.e. particularly in the right stages 

 for class work, a little experimentation on the part of the 

 teacher will afford a much more satisfactory basis for the 

 teacher than anything else. Seeds vary and conditions 

 vary. A good florist, to advise with the teacher, or even to 

 undertake the work of supplying the materials, will be a 

 great help. The student, however, should have a chance to 

 watch the seedlings as they develop. 



VI. Castor Beans should be soaked in warm water for 

 about twenty-four hours, sown in pots or a box of loose 

 earth, about four weeks before they are wanted. They 

 usually start growing one or two at a time, so that after 

 three or four weeks, all stages in germination may be repre- 

 sented in the same pot. The teacher should request the 

 students to compare the caulicle and cotyledons in a well- 

 grown seedling with those organs in the embryo, as regards 

 both size and color. The adult leaf mentioned under 8, may 

 be a pressed leaf, if fresh ones are not available. 



VII. What was said of Peas and Beans, applies as well to 

 Indian Corn.
