and Carroll Horse Company constructed a second such auction mart building in 1913.
With advent of the automobile in the early twentieth century, the use of horses in New York began to decline. At the same time the Fiss, Doerr and Carroll Horse Company was constructing new buildings on East 24th Street, the Bull’s Head Market was starting its decline. In 1905, several buildings on the block, including the Bull’s Head Hotel, were demolished for the construction of tenements. By 1916, only ten years after Fiss, Doerr and Carroll’s vertical stable was constructed, it was converted into a warehouse and rented to the Lord and Taylor department store. In 1922, Fiss, Doerr and Carroll sold one of its auction mart buildings to the H. Kauffman and Sons Saddlery Company, and in 1928 sold the other to the R&T Garage Company, which converted it into a full-service garage for automobiles. The Fiss, Doerr and Carroll Horse Company went out of business soon after. By the 1930s, most of the remaining stables were converted to garages and those on the south side of 24th Street were demolished to make way for the Madison Square Post Office, completed in 1937. By 1939, the only remnants of the Bull’s Head Market were two operating stables and two horse related businesses, the H. Kauffman and Sons Saddlery Company and Miller’s Harness Company. Kauffman’s sold riding gear at this location until 1991 and Miller’s continues to operate on East 24th Street.
