Nature writer Gordon Grice, who started his first cabinet of curiosities at age six when he found a skunk's skull, explains how scientists classify all living things through the Linnaeus system; how to tell real gold from fool's gold; how to preserve butterflies, crab shells, feathers, a robin's egg, spider specimens, and honeycombs; how to identify seashells; the difference between antlers and horns; how to read animal tracks. And then, what to do with your specimens, including how to build a cabinet of curiosities out of common household objects, like a desk organizer or a box for fishing tackle.
