Includes over 200 illustrations by the author. Here are fifty adventures that any of us could have. The only equipment needed is a hand lens and an inquiring mind. At home, in the woods, fields, ponds and along the roadside are familiar things that under the glass show us exciting and sometimes beautiful details that we could not see without this help. Have you ever looked at the antennae of an ant under a lens, or seen the bristles on an earthworm? Did you know that a certain moss has a capsule that looks like a pepper box? A piece of granite seen through a glass shows us that it is made up of various crystals. These are the kinds of things that an adventurer with a hand lens can discover. Not only has the author described these experiments in lively and clear text but he has illustrated them with over two hundred line drawings.
