-II — 



Partially fill a rather shallow box with fine sandy soil. Moisten 

 thorou)jhly. Sow the seeds and cover the box with a sheet of glass 

 (the glass covering should be so arranged as to admit a very little air to 

 prevent mold ). 



2. To see how the roots grow and the root hairs form, grow the seeds 

 in water. The following arrangement is a good one: 



Soak seeds over night in water. The next morning place them in a 

 germinator. This may be made with a saucer, tumibler and a glass jar 

 somewhat larger than the tumbler. Tie the netting over the tumbler, 

 fill with water (A) and place in saucer (C) in which is a little water. Put 

 the seeds on the netting and place the jar (B) over the whole. A moist 

 chamber is thus formed, preventing the seeds from drying. 



3. To watch the growth of roots in soil the following apparatus is 

 excellent: 



Place a sheet of glass about 8x6 inches next a sheet of zinc of the 

 same length, but one half inch wider. Separate the glass from the 

 zinc by narrow slips of glass. Any water proof cement may be used to 

 keep the slips of glass in place. Fill the space between with fine soil. 

 Support the whole on one edge, slightly inclined, the glass on the upper- 

 most side. Plant the seeds in the soil. Keep a black cloth over the 

 glass when the plants are not under observation. 



Encourage the children to bring many forms of seeds which they may 

 arrange for growth as they see fit. 



Aquaria. 



Aquaria of any form will be found to be very useful. A number of 

 glass fruit jars may answer. Where large glass vessels can be obtained 

 their greater advantage will suggest their use. A few extra jars and 

 glass tumblers ought always to be kept on hand to put things in that the 

 children may bring, or for use in collecting. To maintain an aquarium 

 without having the contents spoil and die, requires intelligent experi- 

 menting, which in itself may be a valuable series of lessons. Having 

 the vessels ready the aquarium may be studied from time to time. 



Eggs of Frofes or Salamanders. 



These may be obtained during the winter cime. Secure some and place 

 them in a jar of water. Put but few eggs in a single jar. Do not have 

 the water very deep. Keep a very small amount of green algae in the 

 jar. The development of the eggs into tadpoles, and of the tadpoles 

 into adult animals may be watched day by day with great interest if 

 they are kept successfully. If the eggs are obtained while in the earliest 

 stages of development, the fact can be clearly seen with a hand lens 

 that the little globule which coustitutes the egg is at first a smooth 

 sphere, and then goon has s crease formed on its surface dividing it into
