| Abstract: | Daily pollen counts for the year 1954 in Toronto, Canada, are reported. The tree season is predominantly from the first of April into the second week of July, but after June 1 practically the only tree pollen seen is that of pine. The grass season is predominantly from the fourth week of May through July, but grass pollen is found until the middle of September. The weed season is through August and September, with the peak at the beginning of September. |
