Examine many flowers, now in reference to their stamens and pistils, 

 pollen and ovules. Include forms very different in appearance from the 

 poppy. Examine also grasses in bloom. 



In the poppy and the other plants at hand, next trace the growth ot 

 the ovary into the developed fruit. Many lessons in the future will be 

 given on the different kinds of fruiting and their relation to the distribu- 

 tion of seeds. But this is the best time to observe the development of 

 their forms of fruiting. 



On many plants we can have on a single branch, all stages from the 

 pistil in the flower to the ripened pod or other forms of fruit. 



For examples of very interesting and very common cases take: 



The burr clover, any lupine, alfilerilla, shepherd's purse, wild mus. 

 tard, wild turnip, dandelion. Any other plant cultivated, or weed, will 

 give an interesting lesson. In each, see the use of the particular form. 

 If you do not know the name of the plant you can yourself trace out 

 these changes first, and then make the same process the lesson. 



Following these, will be lessons on the corrolla and its use in attract- 

 ing insects, and managing to get them to carry pollen from one flower 

 to another. 



Ants' Nests. 



An exceedingly interesting and instructive object lor pupils of all 

 grades is a colony of ants so kept that they can be observed in their 

 daily work in and about their nest. 



Students of ants have devised various means for thus arranging their 

 nests. One method is to place the colony in a glass jar partially filled 

 with earth. The mouth of the jar is covered with gauze or netting to 

 prevent their escape. The jar should have its sides covered with a thick 

 dark cloth, which can be removed to make observations. In capturing 

 the colony, if possible the queen should be obtained. Soon after the 

 ants are placed in the jar with the dirt, they will begin to make excava- 

 tions, and some of their tunnels may be against the sides of the glass. 

 If this is fortunately the case their life in the nest may be observed. 



A much better nest was devised by Sir John Lubbock. It consists of 

 two sheets ot glass of about 8 x lo inches. These are held apart at the 

 edges by narrow thin strips of wood, about the thickness of a lead pen- 

 cil, the thickness being but slightly higher than the ants to be confined. 

 These strips are placed between the sheets at their outer edges. At one 

 corner a space of about a quarter of an inch is left, which is to be the 

 door for the entrance and exit of the ants. The remaining space be- 

 tween the glass sheets is filled with pulverized earth, very slightly moist. 



This is to be the nest. This is placed in a shallow box a few inches 

 wider each way than the nest. Around the edges of the box is tacked 

 a strip of fur, which acts as a fence to retain the ants within bounds. 



The margin between the nest and sides of the box give a space for the
