MACHINES THAT ^Ji^EP AXD F^LY.

the worms make are wound 

 with the silk. Men take them 

 to factories, where t'hey are un- 

 wound and made into the beau- 

 tiful silks you and your mother 

 Avear. 



The spider is also a spinner. 

 II is thread is much finer than 

 the silk-worm's. It is made up 

 of a great many threads, just 

 like a rope of many strands. 

 This is the spider's rope that 

 he walks on. He often swings 

 on it, too, to see how strong it 

 is. Did you ever see a spider 

 drop from some high place? 

 How his spinning-machine must 

 work ! 



The wasp makes his paper 

 nest out of fibres of wood.' He 

 picks them off with his strange 

 little teeth, given him for the 

 purpose, and gathers them into 

 a neat bundle. 



When he has enough he 

 makes them into a soft pulp -= 

 in some strange way. This 

 pulp is very much like that 

 used by men in making our 

 paper. Very likely the wasps 

 taught them how, because they 



are the oldest paper-makers in the world. This pulp 

 he weaves into the paper that forms his nest. You 

 must look for one, and see how much it is like the 

 common brown paper we use to wi-ap bundles in. 

 The wasps work together, so that it takes but a 

 very little time to build a nest.
