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. 
A Few Familiar Flowers by Margaret Warner 
Morley, published by Ginn & Co., is excellent for 
teacher’s use in teaching any kind of flower.
