      abstract = {It has been found that in most parts of the United States  from 1 to 2 per cent of the population suffer from hay  fever at some portion of the year, indicating that its  victims may be counted by the hundred thousands. It was not  until about 1870 that the relationship of pollen to the  disease was established. The development of hay fever about  the time of hay harvest led to the belief that this was the  cause of the disease. The particular pollens causing this  disease were for a long time unidentified.},
