The 1821 edition contained a preface which declared, "The good-nature with which this Calendar was received on its appearance in 1819 ... has induced its republication in a separate form, with considerable additions".
[4] The calendar also refers to Shelley regarding autumn when it states: "The poet still takes advantage of the exuberance of harvest and the sign of the Zodiac in this month, to read us a lesson on justice".
[5] For September and autumn, Hunt connected the harvest and the month's zodiac symbol, Libra, in order to discuss justice.
[6] Additionally, Hunt brings up Shelley's poems Convito and The Revolt of Islam in order to discuss autumn, abundance of crops, and revolution.
[7] Hunt also describes the natural events that take place during autumn: "This is the month of the migration of birds, of the finished harvest, of nut-gathering, of cyder and merry-making, and, towards the conclusion, of the change of colour in trees.
The swallows, and many other soft-billed birds that feed on insects, disappear for the warmer climates, leaving behind only a few stragglers, probably from weakness or sickness, who hide themselves in caverns and other sheltered places, and occasionally appear upon warm days.
The descriptions of temperate climates are also connected to medical aspects of British life, possibly representing various illnesses that befall people during autumn.
