National Geographic : 1949 Jul
The National Geographic Magazine National Geographic Photogralupers B. Anthony Stewart and Johln E. Fletcher Set in Soft Velvet and Covered with Glass, Shells Make a Novel Card-table Top Mrs. Roy Halverson and her daughter, of Duluth, Minnesota, find a novel use for souvenirs of a Florida vacation. On the left side are several rows of scallops (Pecten gibbus, page 46, No. 5), and lower right Tellen Shells. The bottom shelf in the background holds specimens of the King Helmet and Frog Conch (Strombus rarinus). Greek architects called "diversity with uniform itv." Each snail has the same architecture-a small round typical shell. Most of them have the same lineal markings. But what a wonderful range of tints and tones. From every angle they are colorful and distinctive. Artists and de signers should study Cuban Land Snails for the nspiration of their color combinations and the originality of blends and tints. Color Page 79 This plate shows a few typical specimens from the vast tree and land fauna that inhabits the Philippines. This architecture is so similar to the land and tree snails of Cuba that one marvels at the world-wide distribution of these creatures whose habitats are separated by vast seas. Color Page 80 To cut shells calls for a special skill and special tools. The pearly substance is much harder than glass. The two lower panels offer a vivid comparison in the spiral designs that result from two different ways of cutting the same shell. This is the com mon Giant Conch that may be found lying on the beaches of the Florida Keys-a veritable art gem rolled up by the waves unappreciated, unless somebody picks it up and explores its marvelous construction.
