Book Description
Tourmaline group minerals have graced the cabinets of mineral collectors and museums for untold generations. Their colors and color patterns, along with their diverse shapes and associations, have assured their role as exqui site showpieces. Their workability and durability have, in addition, made them favorites among connoisseurs of colored gemstones. Tourmalines, however, are much more than exquisite showpieces and beautiful gemstones. Their diverse crystal forms and unique structure, their variable chemical compositions, their intriguing physical properties, and their widespread occurrence in nearly all kinds of rocks have long attracted the attention of scientists from several disciplines. Furthermore, they have several potential uses in science and industry. From an historical standpoint: Tourmaline is possibly the "Lyngurium" -green at one end, light colored at the other-that Theophrastus (ca.315 B.C.) described in On Stones, the first known book about minerals. Tourma line is one of the minerals thought to have been used as a "sunstone" navigation compass by Vikings during the eighth, ninth, and tenth centuries.

Book Description
The qualities of the mysterious tourmaline are unique in the mineral realm. Fourteen years went into creating this volume, including visits to scientific collections all over Europe. Phenomena gave way to outer experience, which led to inner experience and insight; the natural object gave way to natural being. A miracle of nature, the tourmaline is a precious stone, having perhaps the greatest range of figuration and coloring of any gem. The importance of this book is in its lavish illustrations and far-reaching cognitive treatment of the tourmaline. At its heart are approximately 400 color photographs by some of the best photographers. The concluding text takes a Goethean view, explaining how tourmalines came to be invested with such a panoply of meanings, which remained unacknowledged for centuries. This is a book your family will treasure for many generations.

Book Description
I want to die. I do not want to be mad...It is like my body is a house, and some visitor has come, and attacked the person who lived there. After an Australian patrol officer commits suicide on a remote New Guinea island in 1959, five witnesses are called to a government inquiry. Each has a disturbing story to tell: strand by strand, the mystery of the officer’s past is unravelled. But what of other visitants, like the unidentified flying object and the cargo cult it has inspired on the island? Informed by Randolph Stow’s experiences, Visitants is an original, astonishing investigation of colonialism. Julian Randolph ‘Mick’ Stow was born in Geraldton, Western Australia, in 1935. He attended local schools before boarding at Guildford Grammar in Perth, where the renowned author Kenneth Mackenzie had been a student. While at university he sent his poems to a British publisher. The resulting collection, Act One, won the Australian Literature Society’s Gold Medal in 1957—as did the prolific young writer’s third novel, To the Islands, the following year. To the Islands also won the 1958 Miles Franklin Literary Award. Stow reworked the novel for a second edition almost twenty-five years later, but never allowed its two predecessors to be republished. He worked briefly as an anthropologist’s assistant in New Guinea—an experience that subsequently informed Visitants, one of three masterful late novels—then fell seriously ill and returned to Australia. In the 1960s he lectured at universities in Australia and England, and lived in America on a Harkness fellowship. He published his second collection of verse, Outrider; the novel Tourmaline, on which critical opinion was divided; and his most popular fiction, The Merry-Go-Round in the Sea and Midnite. For years afterwards Stow produced mainly poetry, libretti and reviews. In 1969 he settled permanently in England: first in Suffolk, then in Essex, where he moved in 1981. He received the 1979 Patrick White Award. Randolph Stow died in 2010, aged seventy-four. A private man, a prodigiously gifted yet intermittently silent author, he has been hailed as ‘the least visible figure of that great twentieth-century triumvirate of Australian novelists whose other members are Patrick White and Christina Stead’. Praise for Visitants ‘A brilliant, ambitious novel.’ Sydney Morning Herald ‘Tautly and vibrantly written, and brilliantly evocative of its Trobriand Islands setting.’ Australian Book Review ‘Stow is an exceptional writer, truly gifted at capturing the natural environment as well as the essential physical and psychological characteristics of his characters. What makes his work memorable however is his examination of human connections...Beautiful.’ Salty Popcorn
