Elmer Brown Mason (1877–1955) was an American writer. He studied at Yale for a period, but then transferred to Princeton, from which he graduated in 1903. Mason became an entomologist for the now-defunct Bureau of Entomology (USDA) in 1910. In addition, he was a seasoned world traveler. In 1915, his fantastic stories of scientists hunting rare species in the remote corners of the world started appearing. Of note were the five stories featuring swamp-guide, Wandering Smith, in The Popular Magazine, especially "The Golden Anaconda"; and the variety of tales in All-Story Weekly, highlighted by the horror-filled lost-race novelette "Black Butterflies," set in Borneo, and its sequel, "Red Tree-Frogs."
Mason was gassed in France during World War I, suffering permanent disabilities, which sidetracked his writing career. His globe-trotting ceased and his stories exchanged the fantastic for the domestic. His fiction writing career petered out around 1926.
"Black Butterflies," was included in the anthology Rainbow Fantasia: 35 Spectrumatic Tales of Wonder ed. by Forrest J. Ackerman; Anne Hardin.
Pulp magazines (often referred to as "the pulps") were inexpensive fiction magazines that were published from 1896 to the 1950s. The term pulp derives from the cheap wood pulp paper on which the magazines were printed. In contrast, magazines printed on higher-quality paper were called "glossies" or "slicks". The typical pulp magazine had 128 pages; it was 7 inches (18 cm) wide by 10 inches (25 cm) high, and 0.5 inches (1.3 cm) thick, with ragged, untrimmed edges.
The pulps gave rise to the term pulp fiction in reference to run-of-the-mill, low-quality literature. Pulps were the successors to the penny dreadfuls, dime novels, and short-fiction magazines of the 19th century. Although many respected writers wrote for pulps, the magazines were best known for their lurid, exploitative, and sensational subject matter. Modern superhero comic books are sometimes considered descendants of "hero pulps"; pulp magazines often featured illustrated novel-length stories of heroic characters, such as Flash Gordon, The Shadow, Doc Savage, and The Phantom Detective.The Popular Magazine
The Popular Magazine was an early American literary magazine that ran for 612 issues from November 1903 to October 1931. It featured short fiction, novellas, serialized larger works, and even entire short novels. The magazine's subject matter ranged over a number of genres, although it tended somewhat towards men's adventure stories, particularly in the waning years of the publication when the vogue for hardboiled fiction was strong. The Popular Magazine touted itself as "a magazine for men and women who like to read about men." The magazine had its headquarters in New York City.
