Edge of the Jungle is a fascinating book that describes William Beebe's adventures and discoveries in the South American jungles. William Beebe, born Charles William Beebe (July 29, 1877 - June 4, 1962) was an American naturalist, ornithologist, marine biologist, entomologist, explorer, and author. He is remembered for the numerous expeditions he conducted for the New York Zoological Society, his deep dives in the Bathysphere, and his prolific scientific writing for both academic and popular audiences. "I stood beneath the familiar cashew trees, which had yielded for me so bountifully of their crops of blossoms and hummingbirds, of fruit and of tanagers, and looked out toward the distant jungle, which trembled through the expanse of palpitating heat-waves; and I knew how a hermit crab feels when its home pinches, or is out of gear with the world. And, too, Nupee was dead, and the jungle to the south seemed to call less strongly. So I wandered through the old house for the last time, sniffing the agreeable odor of aged hypo still permeating the dark room, re-covering the empty stains of skins and traces of maps on the walls, and re-filling in my mind the vacant shelves. The vampires had returned to their chosen roost, the martins still swept through the corridors, and as I went down the hill, a moriche oriole sent a silver shaft of song after me from the sentinel palm, just as he had greeted me four years ago." "Then I gathered about me all the strange and unnameable possessions of a tropical laboratory--and moved. A wren reaches its home after hundreds of miles of fast aerial travel; a hermit crab achieves a new lease with a flip of his tail. Between these extremes, and in no less strange a fashion, I moved. A great barge pushed off from the Penal Settlement, piled high with my zoological Lares and Penates, and along each side squatted a line of paddlers,--white-garbed burglars and murderers, forgers and fighters,--while seated aloft on one of my ammunition trunks, with a microscope case and a camera close under his watchful eye, sat Case, King of the Warders, the biggest, blackest, and kindest-hearted man in the world."
