Book Description
In his carefully written text, geologist Paul Garvin has combined scientific facts about minerals with an appreciation of their history and beauty to produce a book that will appeal to scholars, collectors, and the general public. Garvin begins with a brief treatment of the origins of Iowa's minerals, moving from the oldest - with ages well in excess of a billion years - to those most recently formed. He describes the state's major mineral occurrences, providing detailed information for both specialists and amateurs, including how to obtain access to collecting sites. A history of Iowa's mineral industries complements Garvin's more technical information; this history is supplemented with stories about the Cardiff Giant (who now has his own web page), Ottumwa's Coal Palace, and the meteor falls of the late nineteenth century.

Book Description
From the spiky teeth of a geode containing sparkling quartz crystals, the rich browns and golds of smoky quartz and goethite needles on calcite, and the coral-like branches of plumose barite to the abstract reds and whites of polished agate cabochons, world-class mineral crystals are harvested from the rocks of the Hawkeye State. Collecting these high-quality crystals requires access to active mines, pits, and quarries, and individual collectors are rarely allowed entrance to these facilities. With information about each specimen’s type, source, size, and current location, Paul Garvin and Anthony Plaut’s Iowa Gems and Minerals in Your Pocket provides access to the glittering, gleaming world of Iowa crystals. Most, if not all, of Iowa’s gems and minerals are products of crystallization in underground cavities that filled with water containing dissolved chemicals. The famed Iowa geodes (Iowa’s state rock) are products of a complex process of replacement and cavity-filling in the Warsaw Shale. Armored by a rind of tough chalcedonic quartz, these spheroidal masses, which range up to more than a meter across, weather out of the host rock and accumulate along streams in the southeastern part of the state. During the Pleistocene Epoch, large masses of glacial ice rafted the ultra-fine-grained variety of quartz called Lake Superior agates, which had previously weathered out of their host rocks, southward into Iowa. They can be found in the gravels that have accumulated along major streams in the eastern half of the state. Iowa’s long record of mining lead, coal, gypsum, and limestone contains a rich history; the forty-seven mineral specimens inIowa Gems and Minerals in Your Pocketmake up a fascinating illustrated guide to that history. Carefully lit and photographed to reveal both maximum detail and maximum beauty, each specimen becomes a work of art.

Book Description
In 1949, Iowa farm wife Evelyn Birkby began to write a weekly column entitled “Up a Country Lane” for the Shenandoah Evening Sentinel, now called the Valley News. Sixty-three years, one Royal typewriter, and five computers later, she is still creating a weekly record of the lives and interests of her family, friends, and neighbors. Her perceptive, closely observed columns provide a multigenerational biography of rural and small-town life in the Midwest over decades of change. Now she has sifted through thousands of columns to give us her favorites, guaranteed to delight her many longtime and newfound fans. Evelyn begins with her very first column, whose focus on the Christmas box prepared by a companionable group of farm wives, the constant hard work of farming, and an encounter with an elderly stranger over a yard of red gingham sets the tone for future columns. Optimistic even in the wake of sorrow, generous-spirited but not smug, humorous but not folksy, wise but not preachy, Evelyn welcomes the adventures and connections that each new day brings, and she masterfully shares them with her readers. Tales of separating cream on the back porch at Cottonwood Farm, raising a teddy bear of a puppy in addition to a menagerie of other animals, surviving an endless procession of Cub and Boy Scouts, appreciating a little boy’s need to take his toy tractor to church, blowing out eggs to make an Easter egg tree, shopping for bargains on the day before Christmas, camping in a converted Model T “house car,” and adjusting to the fact of one’s tenth decade of existence all merge to form a world composed of kindness and wisdom with just enough humor to keep it grounded. Recipes for such fare as Evelyn’s signature Hay Hand Rolls prove that the young woman who was daunted by her editor’s advice to “put in a recipe every week” became a talented cook. Each of the more than eighty columns in this warmhearted collection celebrates not a bygone era tinged with sentimentality but a continuing tradition of neighborliness, Midwest-nice and Midwest-sensible.
