Let's Collect Rocks and Shells

THIS IS A DOWNLOADABLE E-BOOK. After you've had a good day's haul and a rest (you'll need one) you must clean your shells. Put your tiniest, most fragile ones in rubbing alcohol. Put the rest in a pot of fresh water and slowly bring it to a boil. Let them cool in the water slowly to prevent the glossy shells from cracking. When cool, your bivalves will be gaping open; simply scrape them clean. Your univalves will be more difficult; remove the animal with a crocket hook or other piece of bent wire, turning it gently with the spiral; try to get it out whole to save yourself trouble. Save the univalve's operculum and slice it off the muscle that holds it. It will preserve indefinitely and is a valuable part of the shell.Shell Oil Company is the author of 'Let's Collect Rocks and Shells', published 2004 under ISBN 9781419229756 and ISBN 1419229753.
