Perhaps in response to a question by Wood about an advertisement for agents, Elias Clark of St. Louis, Missouri, writes that a prospective agent could buy a machine for $35 retail and test it out before trying to represent the product to others. He states his confidence in the "Raymond Double Threaded Family Sewing Machine," and reports it had been getting good reports from agents in Illinois. Clark's letter to Wood was written on the back of printed "rules for agents" and additional information about the sewing machine business.
