larger, and the naturalist referred to tells of a ten-year-old boy,
son of his neighbour, who, left to mind a canoe while his father went
into the forest, was, in broad day, playing in the shade of the trees,
stealthily enwrapped by one of the monsters. His cries brought his
father to the rescue just in time.

As the Javary heads near the eastern slopes and spurs of the great
Peruvian Cordillera, where once lived the powerful and wealthy Inca
race with their great stores of pure gold obtained from prolific mines
known to them, it is again not surprising that Mr. Lange should have
stumbled upon a marvellously rich deposit of the precious metal in
a singular form. The geology of the region is unknown and the origin
of the gold Mr. Lange found cannot at present even be surmised.

Because of the immense value of the rubber product, gold attracts less
attention than it would in some other country. The rubber industry
is extensive and thousands of the wild rubber trees are located and
tapped. The trees usually are found near streams and the search for
them leads the rubber-hunter farther and farther into the unbroken
wilderness. Expeditions from time to time are sent out by rich
owners of rubber "estates" to explore for fresh trees, and after
his sojourn at Remate de Males and Floresta, so full of interest,
Mr. Lange accompanied one of these parties into the unknown, with
the extraordinary results described so simply yet dramatically in
the following pages, which I commend most cordially, both to the
experienced explorer and to the stay-by-the-fire, as an unusual and
exciting story of adventure.
