curbstoning
 n.— «The regular dealers pay $50 a year license and complain that they daily encounter persons who pay no license, but watch for opportunities to make sales and frequently cause the regular brokers trouble by stepping in when sales are partly completed and claiming a part of the commission. As a first step to check this curbstone business, as it is called, the following letter was yesterday sent to the District Commissioners.» —“After Curbstone Brokers” Washington Post Aug. 10, 1893.
