com^etfel^iii. water ;,.set c fcra>' warm place, being sure that there 

 is enough water in the bottle to thoroughly moisten all the 

 seeds. Determine, in comparison with the sand planting, 

 what the effect of air is on the germination of seeds. 



In a blotter germinator similar to the above, place some 

 seeds of wheat and set the germinator in a warm place 

 without the addition of water to the blotters. 



STUDIES 



1. Make drawings to show the difference in the characters 

 and types of the various seedlings. 



2. What do you conclude in regard to the food supply neces- 

 sary for germinating seeds, as proved by the clipping of the 

 cotyledons of some of the beans? 



3. What factors are essential to germination ? 



4. What essentials in plant growth are not essentials in the 

 germination of the seed ?
