input: Zheng He's sailing charts, the Mao Kun map, were published in a book entitled the Wubei Zhi (A Treatise on Armament Technology) written in 1621 and published in 1628 but traced back to Zheng He's and earlier voyages. It was originally a strip map 20.5 cm by 560 cm that could be rolled up, but was divided into 40 pages which vary in scale from 7 miles/inch in the Nanjing area to 215 miles/inch in parts of the African coast.  Investigation into folios 19V to 20R of the Mao Kun Map which covers the Indian Ocean including the South India, Sri Lanka, the Maldives, and East Africa suggests that it is a composite of four maps, one for Sri Lanka, one for South India one for the Maldives and one for around 400 km of the East African coast, no further south than 6 degrees south of the Equator. Each of these maps is positioned at a different orientation to fit with the ocean currents and winds required of a sailing chart, rather than a formal map. The analysis also suggests that Arabic-speaking pilots with a detailed knowledge of the African coast were involved in the cartography.  There is little attempt to provide an accurate 2-D representation; instead the sailing instructions are given using a 24-point compass system with a Chinese symbol for each point, together with a sailing time or distance, which takes account of the local currents and winds. Sometimes depth soundings are also provided. It also shows bays, estuaries, capes and islands, ports and mountains along the coast, important landmarks such as pagodas and temples, and shoal rocks. Of 300 named places outside China, more than 80% can be confidently located. There are also fifty observations of stellar altitude.

input: In December 1925, Lyman joined the Chicago Bears and took part in a winter barnstorming tour that featured football player Red Grange. He joined the Bears again in the fall of 1926. The 1926 Bears team featured five players who were later inducted into the Pro Football Hall of Fame (Lyman, Paddy Driscoll, George Halas, Ed Healey, and George Trafton), posted a 12-1-3 record, and finished second in the NFL.  Lyman remained with the Bears for the 1927 and 1928 seasons. He retired after the 1928 season but returned to the Bears in the fall of 1930. The 1930 Bears compiled a 9-4-1 and finished third in the NFL. Lyman was selected as a first-team All-Pro by Collyer's Eye magazine and the Green Bay Press-Gazette.  Lyman again retired from playing football after the 1931 season. During his two retirements from the Bears, Lyman played semipro ball in Texas and worked in the ranching business.  Lyman returned to the Bears in 1933. The 1933 Bears featured six future Pro Football Hall of Fame players (Lyman, Bronko Nagurski, Red Grange, George Musso, and George Trafton), posted a 10-2-1 record, and defeated the Giants in the 1933 NFL Championship Game.  Lyman played his final year of professional football as a member of the 1934 Bears team that compiled a perfect 13-0 record in the regular season and won the NFL Western Division championship, but lost to the Giants in the 1934 NFL Championship Game. After the 1934 season, Lyman was selected as a first-team All-Pro by the United Press, Green Bay Press-Gazette, and Collyer's Eye. Bears' coach George Halas later observed that Lyman was "stronger and tougher during his last two seasons than when he first joined the team eight years earlier."

input: After the success of National Comics' new superhero characters Superman and Batman, Fawcett Publications started its own comics division in 1939, recruiting writer Bill Parker to create several hero characters for the first title in their line, tentatively titled Flash Comics. Besides penning stories featuring Ibis the Invincible, Spy Smasher, Golden Arrow, Lance O'Casey, Scoop Smith, and Dan Dare for the new book, Parker also wrote a story about a team of six superheroes, each possessing a special power granted to them by a mythological figure.  Fawcett Comics' executive director Ralph Daigh decided it would be best to combine the team of six into one hero who would embody all six powers. Parker responded by creating a character he called "Captain Thunder". Staff artist Charles Clarence "C. C." Beck was recruited to design and illustrate Parker's story, rendering it in a direct, somewhat cartoony style that became his trademark. "When Bill Parker and I went to work on Fawcett's first comic book in late 1939, we both saw how poorly written and illustrated the superhero comic books were," Beck told an interviewer. "We decided to give our reader a real comic book, drawn in comic-strip style and telling an imaginative story, based not on the hackneyed formulas of the pulp magazine, but going back to the old folk-tales and myths of classic times".  The first issue of the comic book, printed as both Flash Comics #1 and Thrill Comics #1, had a low-print run in the fall of 1939 as an ashcan copy created for advertising and trademark purposes. Shortly after its printing, however, Fawcett found it could not trademark "Captain Thunder", "Flash Comics", or "Thrill Comics", because all three names were already in use. Consequently, the book was renamed Whiz Comics, and Fawcett artist Pete Costanza suggested changing Captain Thunder's name to "Captain Marvelous", which the editors shortened to "Captain Marvel". The word balloons in the story were re-lettered to label the hero of the main story as "Captain Marvel". Whiz Comics #2 (cover-dated Feb. 1940) was published in late 1939.
