The Green Giants--The Story of Plants
Today beneath our feet we find dwarf plants which once were green giants of the Coal Age. We may hold a fossil in our hands of a plant that live 250,000,000 years ago, yet looked very much like a fern of today. The club mosses, horsetails and ferns, mostly miniature plants in northern forests, once grew to be 60-1000 feet tall in the warm, damp climate of the Carboniferous Period. Out of a terrarium, which you might set up in your living room, will unfold this story of a past age of plant life. You will find out how these simple plants reproduce by spores, and you’ll learn how to keep them in a miniature world.
