In New York City, General Grant spends the afternoon at the racetrack
During a highly public visit to New York City, General U.S. Grant and some of his party in the afternoon visited Dubois' Half-mile Horsetrack off upper Eighth Avenue in the city. With numerous figures from the local prominent racing fraternity in attendance, Grant and his group saw several trotting races before returning to their hotel and an evening visit to the theater and a performance of "King Lear."
