Editing Calvert, Texas (section)

===Development and decline===
By 1871, the town claimed to have the largest cotton gin in the world.<ref name=":2" /> However, sources differ on when, exactly, the gin was built. The ''Handbook of Texas'' cites the 1871 date, while a 1931 ''Frontier Times'' piece on Calvert places the building of the gin by John H. Gibson as 1876.<ref name=":1" /><ref name=":2" /> Eventually, P.C. and J.H. Gibson, Jr., took over the gin. It had 21 stands and a connected oil mill. The gin served a significant portion of the Brazos River bottoms. A total of 32,000 bales were reported received in 1882.<ref name=":2" />

In 1873 a severe yellow fever epidemic killed many in the community, severely depopulating the town. An early judge, in speaking about the epidemic, noted: <blockquote>The disease was brought to town by a traveling printer from Louisiana where the fever was raging.  He took a room over the restaurant in the Bailey building and died there.  As many persons as could made an exodus before the town was quarantined.  We lost between three and four hundred persons.  The fever was a terrible epidemic, and our people suffered because we did not know how to treat the disease.  The trains were not allowed to stop in Calvert then and the windows of the coaches were closed until they were far out of town.<ref name=":2" /></blockquote>A county jail was built in 1875. By 1878, Calvert had 52 businesses. Today, the city of Calvert still exists as a Texas municipality. As of 2016, the town's mayor is Marcus D. Greaves.<ref name=":3">{{Cite web|url=https://www.txdirectory.com/online/city/detail.php?id=272|title=Cities: Calvert - Texas State Directory Online|website=www.txdirectory.com|access-date=2016-10-23}}</ref>
