Poetry and music in nature do not perish.This is the theme that Keats developes in his poem "The grasshopper and the cricket",where he says that summer and winter are not to be taken as opposites-they are but parts of the same,wonderful cycle of seasons which keeps repeating itself.Every season has its own beauty and melody,which one must learn to discern for only then one can appreciate and admire the continuity of the stream of life.
