I have engaged a man to accompany us as far as we wish him to go; he knows a part of the region we are to traverse, though not all of it, but thinks he can learn enough as he goes along. Our route will be through northern Bolivia, past the base of Sorata, the grand mountain we have admired so much, and then down the eastern slope of the Andes till we reach the waters of the Beni River.

"The Beni is a tributary of the Madeira, and the Madeira flows into the Amazon. When we leave Puno to-morrow our watchword will be,

"To the Amazon!"
