eat the cabbages. If you watch a toad in the garden, you will find that 

 he eats many destructive insects. 



Now I hope that there will be well-stocked terrariums in many of 

 your schools. You will enjoy watching the little wild neighbors and you 

 will learn a great deal from your observations. Here are a few^ things 

 you ought to remember in trying to make your visitors comfortable : — 



1. The terrarium world will need an occasional shower. A small 

 watering can is convenient for this purpose. 



2. A partition should be built between turtles and frogs for they do 

 not always live in friendly relations. 



3. Try to find the food that your terrarium folk will eat. Cater- 

 pillars should have fresh leaves from the plant on which you find them 



feeding. Your butterflies may 

 sip the sweets from flowers. 

 Put some thistle blossoms, 

 milk weed plants, and other 

 flowering plants where they 

 can reach them. In fresh 

 mosses and rich soil the toads 

 and salamanders will prob- 

 ably find food to their liking.

When boys are fishing in 

 ponds and streams, they often 

 find interesting water forms. 

 These should be taken to school and placed in a glass jar filled with water, 

 Fig. 3. Unless the aquarium jar is large only a few things .should be 

 kept in it at one time. Place a few stones in the bottom, but do not put 

 mud into the jar. I find that the water salamanders, water insects, and 

 little fishes will eat fish food. They will also eat each other, if you are 

 not careful. The large dark-colored beetles (predacious diving beetles) 

 are not at all considerate for their associates and will eat whatever they 

 can reach. You would better keep them by themselves in a INlason fruit 

 can. The water scorpion that looks like a twig will dispose of your small 

 fishes. 1 think that he, too, should live by himself. 



Uncle John will hoj^c to hear of some interesting experiences 

 that Junior Naturalists have had in their study of animal life found 

 in the water.
