When a woolly mammoth died on the Siberian tundra, it sometimes fell into a quagmire. There the permafrost, operating like a modern freezer, preserved the carcass intact for thousands of years. In temperate New Zealand there was no permafrost but in South Island's Pyramid Valley paleontologists have found a good substitute. From about 18,000 B.C. until 2,-000 years ago, the valley contained a swamp whose lush vegetation attracted moas-great, flightless birds which weighed up to a quarter...

In the remaining 52% there is plenty of room for expansion, for only 7-10% of the total is cultivated at present. Dr. Salter believes that virtually all of the 52% could be made productive if there were good reason to make...

Located where the tree line meets Hudson Bay, it offers both timberland and tundra. And what it lacks in low temperatures is more than made up by its high winds...

Here is the world which "knows but two seasons: winter and August"; here great rivers of North America and Asia drain away and congeal into the titanic ice-blocks of the Arctic Ocean; here (and not at the North Pole) the thermometer has touched its recorded lowest (93° below zero) and the milk of Siberia...
