CHAPTER IX. 
A SPIDER’S ACTIVITIES. 
PLACE a living spider in a large glass jar and watch 
its movements for several days. Get a garden-spider 
if possible, and keep it well supplied with flies and 
other insects. 
How does it take its food ? 
From what part of its body does its web issue ? 
Do all spiders make the same kind of web ? 
Where have you seen spiders ? 
Where have you seen the eggs of spiders ? How do 
they look ? 
Have you seen cast-off skins tangled in spiders’ 
webs ? If so does that indicate anything about the 
spider’s mode of growth ? 
Can the spider smell ? Test this point by bringing 
near the insect first a clean glass rod and then a rod 
dipped in a liquid having a strong odor. 
Can the spider see ? How far from her body can 
she see ? 
Using an alcoholic specimen, write resemblances and 
differences for spider and grasshopper. 
How many divisions of the body ? 
Simple or compound eyes ? How many ? 
How many legs ? 
How many segments in each leg ? 
Examine the feet with a microscope. 
At the end of the mandibles find the poison-fangs. 
Where are the spinnerets ? How many do you find ?
