A Crystal Age by William Henry Hudson

William Henry Hudson was a well-respected author and naturalist. Hudson was born in Argentina to two English settlers and he would eventually settle in England where he produced many ornithological studies.  Hudson is now best remembered for books such as Green Mansions, A Crystal Age, and The Purple Land That England Lost.

A Crystal Age, published in 1887, is a utopian novel  that is notable for its prediction of the modern ecological mysticism that would occur more than a century later.
