Encased in ten tons of the latest technology, a group of scientists and journalists attempts to blast its way over 3,000 miles and half a continent-from the Republic of Senegal to Timbuctoo and beyond. The expedition's ultimate goal-the great Lake Tchad, a little-explored waterway the size of Wales, right in the heart of Africa.

The scientists are hoping that a study of the lake might provide some information which will help fight the problems of ecology at present facing the modern world. The technologists are hoping that their hovercraft will prove to be the ideal means of transport for such a rigorous journey. For, if successful, might not such machines bring untold benefits to a people for whom time stands still?

In retrospect the explorers have their doubts. For how can their blustering vehicle enhance a life-style which, though harsh and frugal still has the capacity for joy and the simple dignity of being alive?
