Re-creating a link with the past, Michael Katzev makes a cast of a chain possibly car ried by an Islamic ship that sank near the Roman wreck (page 411). Like the wrecks' other iron tools and fittings, the link had long ago rusted away, but not before sedi ment had formed a mold around it. After cutting this cross section with a diamond tipped saw, Mr. Katzev pours in a rubber compound that hardens into a cast. Concern for colleagues working below shows on the faces of expedition leader George F. Bass and assistant Susan Katzev. Dr. Bass is Associate Pro fessor of Classical Archaeology at the University of Pennsylvania and Curator of the University Mu seum's Underwater Section. As if wrestling a huge bubble, divers prepare to launch a unique underwater telephone booth (pages 408 414-15) from a barge above the Roman wreck.
