DADDY-LONG-LEGS, CENTIPEDES, AND MILLIPEDES. 133 



be cannibals, as some have been seen to pounce upon a brother 

 daddy-long-legs and devour it, leaving only the legs. 



It is believed that in the Northern States they do not sur- 

 vive the winter, as in the spring only young ones are seen, 

 and these attain full size by autumn. At this season, the eggs 

 are laid under stones and in the cracks of boards and other 

 protected places, where they remain to hatch out in the fol-

 stones and dead leaves in the fields and woods, the pupils 

 will find the creatures to be studied in this lesson. They 

 are commonly known as centipedes, and in the Eastern States, 

 at least, are also known as earwigs ; though the earwig 

 in England is an entirely different animal, being a true six- 

 legged insect. 



The centipede belongs to a group of animals called Mijri- 

 ojpods, and the animals belonging to this group are composed 

 of a great many similar segments, some species having as 

 few as ten segments, others having over two hundred seg- 

 ments. In this latter respect, these creatures resemble the 

 worms, but differ from the worms in having jointed legs and 

 antennae, and in these last-named characters resemble the 

 insects, besides having other affinities with the insects, in 

 breathing air through spiracles and tracheae which run 

 through the body. 



There are two very distinct groups of Myriopods ; one 

 group comprising the true centipedes, in which the body is 

 flattened, the segments loosely joined, and the legs gener-
