The principle part of this latest book by M. Norbert Casteret is an astonishing account of the gradual exploration and final conquest of the vast cavern of Pierre Saint-Martin in the Pyrenees. This thrilling story covers a period of four years - from the discovery of the chasm in 1950, through the disastrous expedition of 1952, through the triumphant day in 1953 when M. Casteret's party, having passed through several gigantic chambers, reached a depth of 730 meters, to the expedition of 1954 when further exploration was carried out and several members of the party risked their lives in the heroic recovery of Marcel Loubens's body.

M. Casteret's moving and awe-inspiring account is followed by an interesting summary of his earlier work as a speleologist in other famous caverns.

The Descent of Pierre Saint-Martin contains chapters not only of adventure as thrilling as any tale of fiction, but also of great scientific interest. We believe that it surpasses every other work which has come from the pen of the greatest of all cave explorers.
