     During the 19th century, farmers in and around Southeast began to invest in a new and unique

business venture (冒险活动). This area would later become known as the origin of the American circus(马戏). In 1793, Englishman John Bill Rickets introduced Americans to the circus at his place in

Philadelphia where trick riding was featured along with clown(小丑) acts in the same show.    

     In the 1830s, farmers in Southeast began showing menageries(野生动物), collections of interesting

animals from far away lands. They soon combined the menagerie show with the acrobatic(杂技的)

entertainment of trick riding and these early circus bosses began taking their show on the road. By the

1850s American circuses were a big business and they began to travel abroad, bringing back to

American even more unique items and animals.    

     Hachaliah Bailey, from nearby Somers, Westchester County, brought the first elephant "Old Bet" to

the United States in 1796. Bailey exhibited "Old Bet", until her death in 1816. Somers is home to the

Elephant Hotel, built by Hachaliah Bailey in 1820-1825. The building served as a meeting place for

menagerie owners.
