Another subject discussed was the character, variety and quantity of advertising matter to be prepared. It was reported that an experiment in selling Seals through penny-in-the-slot machines had proved unsuccessful, and this method of distribution was disapproved. From many agents it was learned that the sale of Seals through a simple mail order system had proved successful and inexpensive. In many busy offices agents for the Seals find it difficult to obtain a hearing by personal calls, when a brief, well-expressed letter will receive a prompt and favorable response. In certain cities fully half the Seals sold in 1912 were disposed of in this manner. It was found to be the consensus of opinion among agents that the offering of prizes for the sale of Seals, especially individual prizes to school children, is inadvisable. A few agents reported the successful use of prizes for schools, but not to individual pupils, without apparent disadvantages. All agreed that great care must be exercised in offering prizes in order to avoid stimulating children to improper methods. Several agents reported that citizens of their communities had complained of annoyance because of the numerous calls at their doors by children desirous of selling Seals. One agent described a method of avoiding this nuisance which has proved completely successful in his community. This method is for a citizen who has purchased Christmas Seals to paste one of the seals on his door knob or front door. Any child approaching a door and seeing a seal thus posted, understands that he is not to disturb that household, as its supply of Seals is already purchased. By announcing this system of protection through the press and in the schools it is said to have fully accomplished its purpose. Tn Ohio the State agent for the Seals adopted a method of awarding prizes which is reported to have been extremely successful, not only as a stimulus to the selling of Seals, but as an educational factor. The agent offered to supply a visiting nurse for one month to each of the twelve cities in the State of Ohio which sold the largest percentage of Seals in proportion to its population. A trained visiting nurse was employed by the State agent for one year and was sent in turn from city to city among the prize winners, serving one month in each locality. Not only did this prove an extremely popular arrangement, but in six of the cities benefited by the plan in 1912, the public became so impressed by the value of the visiting nurse that they arranged to employ nurses permanently upon the withdrawal of the prize nurse.
