The Frogs Eggs. 93 



"Some of the eggs have hatched, and those 

 are little tadpoles. Now, you must go to the 

 pond and get some pond-weeds for them to eat." 



" Yes, I will go ; but will the tadpoles ever be 

 frogs ? " asked Albert. 



" Watch them, and see what you think about 

 it," said his uncle. 



Albert did as his uncle told him, and this is 

 what he saw. 



Soon, some gills, which the tadpoles used in 

 breathing, grew outside the head. 



When the tadpoles had grown a little more, 

 the hind legs began to develop. The gills grew 

 smaller. Then the front legs appeared, and the 

 tails became shorter. The gills were covered by 

 a thin skin, and changed into lungs. 



Then, much to Albert's delight, three little 

 fellows hopped out of the tub, little frogs 

 with tails. But these tails grew smaller and 

 smaller, and at last disappeared. 



Albert knew that the frogs would be happier 

 near a pond, so he took them to one near by, 

 where many of their relations were croaking.
