Burr managed a Long Island farm and a hotel at Townline and Burr Roads, with a talent for spotting good horses. At the 1853
American Institute of the City of New York livestock show, Smith Burr received 1st premium, earning a silver cup for the best three-year-old
colt and a certificate for his stallion Columbus. Columbus, one of Burr's prized horses, fetched $3,000 from buyers in
Detroit, Michigan. Around this time, two full sister
fillies by "Burr's Napoleon" were purchased by a supporter of
Napoleon III and presented to the
French Emperor, who prized and drove them in his prime. His son, Carll S. Burr Sr., succeeded him in the
family enterprise. He expanded the family stables into a business that drew clients like the Vanderbilts, Morgans, and U.S. Presidents
Grover Cleveland and
Ulysses S. Grant. ==Political career==
