During the last 30 years the study of the magnetic properties of rocks and minerals has substantially contributed to several fields of science. Perhaps the best known and most significant advances have resulted from the study of palaeomagnetism, which led to quantitative confirmation of continental drift and polar wandering through interpretation of the direction of remanent magnetism observed in rocks of different ages from different continents. Palaeomagnetism has also, through observations of reversals of magnetiz­ ation, ancient secular variation and ancient field intensities provided data relevant to the origin of the geomagnetic field, and other investigations have contributed significantly to large-scale and local geological studies, the dating of archaeological events and artefacts and more recently to lunar and meteoritic studies. Rock and mineral magnetism has proved to be an interesting study in its own right through the complex magnetic properties and interactions observed in the iron-titanium oxide and iron sulphide minerals, as well as contributing to our understanding of remanent magnetism and magnetization processes in rocks. Simultaneous with the development of these studies has been the develop­ ment of instruments and techniques for the wide range of investigations involved.

A compelling story of a young spaniel puppy desperate to be loved. With a promise of becoming a "gundog" and working with the gamekeepers, Tinker's dreams are shattered when this does not happen. Dismissed and neglected, Tinker spends her puppyhood days alone in a kennel, except for a tiny orange creature who befriends her. After running away twice and creating havoc along the way, is Tinker in danger of being sent to the Dog Pound for good? The tiny orange friend appears in every picture with Tinker, but only special children can see him; will you?

In Tinker's greatest adventure, she battles to save a secret world, which comes under threat from the forces of evil. Murderous creatures from the deep want a world where nothing good exists; in fact, where nothing exists except Them! Mother Nature is hanging by a thread, and the equilibrium of life that reigns cannot last much longer; unless some brave soul undertakes the challenge to save all that is good and kind. A terrifying and treacherous journey lies ahead. Is Tinker up for the challenge and is the little spaniel smart enough to outwit the many dangers along the way? And will the world be ruled by Them! or us?
