Adventures in the Search for Man Islands we collect many of these wonders of nature, not only beetles but caterpillars, flies, ants, a slug, a worm, and the like (page 142). We have even added the fossilized breast of a bird to our collection, and one day Mary made the amazing find of the fossilized head of a large lizard. Its very eyeballs were pre served, the tongue was still sticking out of the mouth, and the creature's tiny scales were perfectly reproduced. These are things to make a paleontologist rub his eyes in wonder, but even more fan tastic are the fossilized flower buds, berries, nuts, and fruits we have found. I wanted to see whether we were dealing with mere casts or with completely fossilized material; so I had some of the specimens cut into cross sec tions.

In some cases we World's oldest known structure, possibly a windbreak, fascinates Mary S. Griswold, a member of the Society's staff.

On this an cient campsite, exposed in 1960 by work men slicing through layers of clay and vol canic ash, a child's skull bone told the dark tale of a crushing blow. Dr. Leakey, kneel ing, points out the stratum that yielded 1,750,000-year-oldZinjanthropus.The child proved to be even older than Zinj, since it lay in a deeper stratum. Dr. Thomas W. Mc Knew (stooping), Vice Chairman of the So ciety's Board of Trustees, Dr. Carmichael, and Jonathan Leakey examine the evidence. Discoverer of Kenyapithecus cleans a fossil in the field. Heslon Mukiri, Dr. Leak ey's senior African assistant, quickly recog nized the importance of his find.
