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-

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

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

 will find the other 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 ear-

 six-legged insect. 



The centipede belongs to a group of animals called Myri- 

 apods, and the animals belonging to this group are composed

 air through spiracles and tracheae which run through the 

 body. 



There are two very distinct groups of Myriapods ; one 

 group comprising the true centipedes, in which the body is 

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