Poor Will's Almanack for the fourth week of Early Fall
Since I started my record of the weather and natural history, I have my kept notes together for each day of the year -for example, all the October 2nds from 1979 through 2012 in one place. With that organization, I've been able to see how, in spite of the separate character of each 12-month cycle, and the possible changes in the climate, the progress of the seasons remains nearly identical from one year to the next.
That arrangement of observations also makes clear the replicable nature of the days themselves instead of their linear succession away from one another. In my daybook, the notes from one afternoon are often interchangeable with those of another afternoon, the same day 10 or 20 years later.
