observe. Provide flies and other small insects for food, 
and watch the web-making, the feeding, and other 
activities. Further questions 
and suggestions will be found 
in Chapter IX. 
Earthworms. Fill one or 
two large battery-jars with 
moist earth and decaying 
leaves and put in each jar 
several earthworms. Cover 
the jars and keep the earth 
well moistened. Keep all 
winter. Watch in connec- 
tion with directions in Chap-

Turtlesand Snakes. Line 
the bottom of a large box 
with sheet-lead or zinc and 
place panes of glass in the 
sides for windows. Put

and, if convenient, a few 
growing ferns in the box. This makes a good home 
for turtles and snakes. Snakes caught late in the 
fall will probably not eat anything through the winter, 
and they can be set at liberty in the spring. Turtles 
seldom eat in the winter, but will take flies, bits of 
meat, or pieces of cracker soaked in milk when 
hungry. ‘‘The Vivarium ’’, an illustrated book by G. 
C. Bateman, will be of great assistance to pupils who 
are willing to care for these animals. 
Frogs. Ina box like that described in the preceding 
paragraph keep several frogs. In the winter frogs do 
not commonly take food. Live frogs can usually be 
bought in the markets. 
Slugs. These animals are easily kept if provided 
with moisture and food. They eat bread or cracker 
as well as many kinds of vegetables.
