Rollo's Philosophy. [Air]

"Rollo's Philosophy. [Air]" by Jacob Abbott is a children's book from the 1800s that introduces young people to ideas about air. It probably stars a boy named Rollo and his cousin Nathan, who play games and explore the world around them while learning about air. The story begins with Rollo, Lucy, and Nathan getting ready to have fun in the snow during winter but soon find themselves in trouble when it begins to snow hard and they get disoriented. Rollo uses his mind to try and find a way out when they find some animal tracks. Abbott mixes excitement and scientific questions to get kids thinking about air and the outdoors while they read about Rollo and his friends.
