fall, otherwise it will not grow down the tube. How 

 careful those little men (the stamens) that hold the 

 pollen are! They certainly do not sleep much, 

 for, just as soon as they know the stigma is moist, 

 they must open their little baskets and let the pol- 

 len fall on it. They must be quick in their work, 

 for the stigma will not stay moist long. Like most 

 other factories, the Spring Beauty closes up at 

 night, by drawing its petals and .sepals tightly over 

 the inner parts of the factory, so as to shut out the 

 night air, rain, and night insects that come to do 

 harm. This factory, in course of a month or two, 

 will turn out some fine seed, which will fall to the 

 ground when the pod splits open, and be ready to 

 start a new plant for another year. Watch these 

 Spring Beauties and Mustards to see what they 

 will do. The old plant will die down when frost 

 comes, but it, too, will spring up again at the re- 

 turn of the song birds from the South. 



Deal with the mustard factory in same way.' 

 Also a few of the others studied. Watch for the 

 seeds as the pods ripen. See (4) of this course. 



Make drawings of spring beauty, mustard, but- 

 tercup, bloodroot, or other plants studied.
