Mowgli grows up
Now you must be content to skip ten or eleven whole years, and only guess at all the wonderful life that Mowgli led among the wolves, because if it were written out it would fill ever so many books. He grew up with the cubs, though they, of course, were grown wolves almost before he was a child.
And Father Wolf taught him his business, and the meaning of things in the jungle, till every rustle in the grass, every breath of the warm night air, every note of the owls above his head, every scratch of a bat's claws as it roosted for a while in a tree, and every splash of every little fish jumping in a pool meant just as much to him as the work of his office means to a business man. When he was not learning he sat out in the sun and slept, and ate and went to sleep again.
