  • "Phenology is the science of natural occurrences, yearly events like the first snow, the first blooming of hepatica and the arrival of the first whippoorwill. Keeping diaries of such occurrences was a hobby of counts and lords in Europe, and there are records in Kyoto, Japan, of the flowering of cherry blossom trees dating back 900 years. Among the most notable American phenological records were those kept by Thomas Jefferson at Monticello and Henry David Thoreau at Walden Pond."
