The big ones are black, with spots and stripes, and have thick coats like fur. If you could find a tower spider, or a trap-door spider, and sit down to watch it build or catch its food, I think you would be happy for a whole day, or for many days. The tower spider builds over her hole a neat tower two or three inches high; she sits on her tower. She has as many as fifty baby spiders at once. They sit on her back for four or five weeks, until they molt two or three times. They do not fight with each other. When Mrs. Spider gets a fly or bug for the little ones to eat, she crushes it, and the baby spiders come and suck the juice, as she holds the food for them. LESSON XXXII. REVIEW. What is an insect? Name some kinds of insects. Can you tell me how an insect’s body is made? How many legs, wings, and eyes do insects have? What three kinds of bees live in each hive? Tell me what the queen bee does. What does a drone bee do, and how does he look? Which bee makes cells? How do bees get honey and wax? Tell me how nurse bees take care of bee babies. How can nurse bees make a new queen bee? Why do the queen bees fight? Tell me about the fight of the queen bees. Why does a swarm of bees leave the hive? What do bees eat? What do they make? Tell me of odd places where bees live. What things eat the bees and steal their combs? How must you take care of bees, if you have them? What colors do bees like best? Tell me about ground bees. Tell me about mason bees. Do all bees make combs with cells that have six sides? Is a spider an insect? In what is he not like other insects? What can a spider make? How does the spider spin a web? Tell me about the spider’s eyes. How does a spider tend its young ones? Tell me about the water spiders. What can you tell about other queer spiders? What does a spider eat? What good things can you say for the spider? LESSON XXXIII. OUT OF HARM’S WAY. By this time I am sure you think that all the small bugs, flies, spiders, and crabs must soon be dead. You have found how cold kills them. You have heard how they kill each other. You know that men and birds and beasts kill them. How can any live? What is there to save the poor things? The two chief things that save them are their shape and their color. Why, how is that? Let us see how this is done. On the sand by the sea the crab that lives mostly out in the air is of a gray color. It has fine red spots like sand. The shell of this crab looks so like sand that, if he lies flat and still, you can scarcely see him. The crab that lives on the sea-side mud is black-green like the mud. Birds cannot see him very well, he is so like the mud that he lies on. The spiders that live in the woods are of much the color of a dead leaf.
