Rudyard Kipling: The Jungle Book. First and Second Volume (English Edition). Rudyard Kipling

"Bagheera would lie out on a branch and call, «Come along, Little Brother,» and at first Mowgli would cling like the sloth, but afterward he would fling himself through the branches almost as boldly as the gray ape. He took his place at the Council Rock, too, when the Pack met, and there he discovered that if he stared hard at any wolf, the wolf would be forced to drop his eyes, and so he used to stare for fun."
