In this useful and fascinating book, Dr. Zim tells all about North American snakes. He explains how they produce their young — some snakes by bearing them alive, some by laying eggs; how they grow; the several ways by which they move. His description of their inching movement, a kind of walking on their ribs, is particularly interesting.
Scientists have found that many kinds of snakes are valuable because they eat rats and mice, and people are learning not to kill the harmless ones. Since some people even keep snakes as pets, Dr. Zim tells how to house and feed them.
James Gordon Irving's pictures, as strikingly beautiful as they are accurate, will help to convince you that snakes are worth seeing, worth knowing, and worth protecting from people who do not understand them.
