The Manila hemp is derived from a species of banana originally from the Philippines, whose fibers are tough. The hemp is then used during the paper making process, similar to how Kraft paper uses wood pulp. So the mystery is solved, the manila envelope gets its name from the hemp in which it is made from.
It is made up of a nucleus (solid, frozen ice, gas and dust), a gaseous coma (water vapor, CO2, and other gases) and a long tail (made of dust and ionized gases). The tail develops when the comet is near the Sun. Its long ion tail of always points away from the sun, because of the force of the solar wind.
J. M. Barrie did not invent the name Wendy for his 1904 play Peter Pan, the Boy Who Wouldn’t Grow Up (the book form of the story, Peter and Wendy, was published in 1911). He did popularize it, though. Barrie apparently was inspired to use the name by a young friend named Margaret Henley, the daughter of writer William Henley. Margaret, who died around 1895 at age 6, called Barrie her “friendy.” Since she couldn’t pronounce her Rs at the time, the word came out “fwendy,” or “fwendy-wendy,” in some versions of the story. But we have absolute proof that there were earlier Wendys, thanks to the just-released 1880 U.S. Census and the 1881 British Census. These documents show that the name Wendy, while not common, was indeed used in both the U.S. and Great Britain throughout the 1800s.
