TWO friends, one an archeologist and the other a mining engineer, determined to take a trip into the jungles of the north of South America. The incitement was some golden ornaments which the archeologist has received from that region, and without knowing it they find themselves following the example of the explorers of the days of Queen Elizabeth and unwittingly go in search of El Dorado. A wonderful presentation of their adventures in South America among the different tribes of Indians follows, and while the Indians are all friendly at first there is the ever-present danger of an outbreak, so that in a sense they are living on the edge of a volcano, as the proverbial saying goes. An outbreak finally occurs during a period of drunken revelry. They have seen gold used almost in profusion by the Indians for their personal adornment; however, the source of this gold is a secret known only to the Chief Medicine Man. But at last trouble occurs, brought on by the killing of one of the Indian tribe by the explorers' guide.
