Published in 1983, the volume collects the detailed accounts of the long and numerous research trips throughout the Mediterranean area, to which the scholar personally identified and chose the queens of the purest strains of each breed, then introduced them to the abbey's apiaries in England, and then studied them for decades, breeding them in purity and in crossbreeding-as his famous comparative tests well document. In the journals of his travels, the backdrop is the scenery of countries very different from each other and in the history they are passing through: the monk's encounters with bees, beekeepers, personalities and institutions turn into fascinating tales that draw the reader into distant and now vanished worlds (even when it comes to Italy!). Documented by the photographs of the time, these journals full of reflections and considerations constitute a work of immense historical value for bee geography-not only of bees but also of man's work. Father Adam observes alpine valleys and deserts, forests and mountains, almost always in the flowering season and always from the point of view of bees and their lives, in very different habitats and grappling with different problems. All, as is his custom, without ever losing sight of the purpose and the practical goal, the search for the 'best variety of bees,' the treasure, to be brought back home, like a modern Jason, to be a gift to mankind.

Hitherto unknown to the Italian public, although published in 1975, this book in countries such as France, Germany, Great Britain and the United States has been considered a classic of beekeeping literature for decades. Told in the first person, we read in it the story of exceptional pioneering work in the field of 'bee breeding and selection, a tale that at the same time is an exemplary introduction to modern beekeeping. Easy and exciting, the book recounts sixty years of work, progress, and study, and is a very rich mine of reflections and practical advice on how to understand and practice beekeeping with excellent results in full and natural respect for bees, the environment, and human labor. "This book is not a manual, but a general account of beekeeping that we have developed at Buckfast. As you will observe every piece of equipment, every operation, every aspect of conducting has been designed to achieve the best possible results by aiming, on our part, to achieve minimum effort and maximum time savings. At the same time, we have tried to pay due regard to the bee's behaviors and instincts. Although it is endowed with a marvelous capacity for adaptation, it does not allow its immutable instincts and its truly amazing organization to be ignored without one later finding oneself paying the bitter consequences."
