THE TICKS GET ON A COW. 



A cow walked slowly by the spot where the little 

 ticks were hiding. 



The ticks smelled blood and got ready to get on 

 the cow. 



Many of the seed ticks were able to get on her 

 tail or her neck or her legs. 



Every baby tick on the cow began to hunt for a 

 thin place in her hide. 



As soon as each tick had found a tender spot, it 

 began to bury its head in the hide. It was digging 

 a tiny well to the blood in the cow. 



Here are seed ticks driving their little wells to the 

 blood in the cow:

When the baby ticks got their first taste of blood, 

 they began to suck blood as fast as they could. 

 Eveiy day they grew a little larger. They sucked 

 blood and grew for about a week. Then they shed 

 their skins, which is called molting, and became 

 little 8-legged ticks.
