The very idea of a bird is a symbol and a suggestion to the poet. A bird seems to be at the top of the scale, so vehement and intense is his life, large-brained, large-lunged, hot, ecstatic, his frame charged with buoyancy and his heart with song.

The Infinite cannot be measured. The plan of Nature is so immense, but she has no plan, no scheme, but to go on and on forever. What is size, what is time, distance, to the Infinite? Nothing. The Infinite knows no time, no space, no great, no small, no beginning, no end.

To strong, susceptible characters, the music of nature is not confined to sweet sounds.
