It has been my lot to cross bleak Andean passes, where there are heavy snowfalls and low temperatures, as well as to wend my way through gigantic canyons into the dense jungles of the Amazon Basin, as hot and humid a region as exists anywhere in the world.

Next in number to the flamingoes were the beautiful white gulls (or terns?), looking strangely out of place in this Andean lake 11,500 feet above the sea.

In Andean villages, even little children do not go naked as they do among primitive peoples who live in warm climates.

Gazing in awe at this sign were Indian boys from some remote Andean village where the custom is to wear ponchos with broad fringes, brightly colored, and knitted caps richly decorated with tasseled tops and elaborate ear-tabs, a costume whose design shows no trace of European influence.

The usual route for those going to Yucay is northwest from the city, over the great Andean highway, past the slopes of Mt. Sencca.

In 1915 rumors of Andean or "spectacled" bears having been seen here and of damage having been done by them to some of the higher crops, led us to go and investigate.

They were veritably impassable during a large part of the year even to people accustomed to Andean "roads.

The effects of this may still be seen in the ruins of small fortresses found guarding the way into isolated Andean valleys.

That the secret of its existence was so well kept is one of the marvels of Andean history.

The term usually applied by Peruvians to the heavily forested slopes of the Eastern Andean valleys and the Amazon Basin.

According to some exceptionally good geological observers, this is probably due to the fact that in a remote geologic past the ocean sent in an arm from the south, between the Plan Alto and what is now the Andean chain.

These rivers then emptied into the Andean Sea.

The gradual upheaval of the soil has resulted in substituting dry land for this arm of the ocean and in reversing the course of what is now the Madeira, just as, according to these geologists, in somewhat familiar fashion the Amazon has been reversed, it having once been, at least for the upper two thirds of its course, an affluent of the Andean Sea.

The work of the archaeologists among the immeasurably ancient ruins of the low-land forests and the Andean plateaux is of this kind.

If we consider only the biological facts concerning some one group of animals it is not only easy but inevitable to conclude that its distribution must be accounted for by the existence of some former direct land bridge extending, for instance, between Patagonia and Australia, or between Brazil and South Africa, or between the West Indies and the Mediterranean, or between a part of the Andean region and northeastern Asia.
