Bit by bit a hole was chipped through the door of an underground chamber sealed for 3,000 years. By flickering candlelight, two scientists peered at the treasures it contained.

More than a third of a mile beneath the surface of the sea, two other scientists looked out on a strange new world from the windows of their hollow steel diving ball.

And on the icy peaks of Mt. McKinley a tiny group of men fought their way to the 20,000-foot summit.

In each of these hair-raising adventures, men risked personal disaster in the search for scientific information. In All About Famous Scientific Expeditions Raymond Holden tells the thrilling stories of five of the great scientific expeditions of the world. As you read this book, you will follow him up a snow-capped mountain, into the Arctic, to the ocean depths, to hunt dragons in the tropics, and to find treasures in an Egyptian tomb.

Most important, you will see how men of courage have persevered in their determination to add to our knowledge of science.
