Jules Verne wrote the book Eight Hundred Leagues on the Amazon, which was first released in 1881. It was also released under the title The Giant Raft. A ranch owner named Joam Garral, who lives close to the Peruvian-Brazilian border on the Amazon River, is forced to travel downstream as his history catches up with him in this adventure novel. The majority of the book takes place aboard a sizable jangada, a Brazilian timber raft that Garral and his family use to float to Belém, which is located at the river's mouth. The voyage, scenery, and many other features are detailed in great depth. In the plot, Joam Garral approves his daughter's request to visit Belém, where she intends to wed Manuel Valdez in front of Manuel's ailing mother. The Garrels use a massive timber raft to navigate the Amazon River. Joam wants to clear his name in Belém since he is still wanted in Brazil for a crime he did not commit. Absolute evidence of Joam's innocence is provided to him by the rogue Torres, but Joam finds it incomprehensible that Torres would demand to wed Joam's daughter in exchange for this information. An encrypted letter contains the evidence that will clear Garral.
