What is the author's tone in The Jungle Book by Rudyard Kipling?

Kipling creates somewhat childlike phrases and words in the stories; such as, "Jungle People" to describe the ordered denizens of the jungle, "Gidur-log" to describe the jackals, and "Bandar-log" to describe the wild monkeys. These names have their roots in the Hindu language, and even Kaa's name is drawn from the Hindu word for snake.
