In Section 9 of "Song of Myself" by Walt Whitman, what does he take pleasure in?

While Whitman never says that he takes pleasure in
anything in particular; he gives us a very pleasurable scene and his action in it from
which to infer his pleasure.  He has taken pleasure in using his body for hard work.  He
enjoys the play of the light on the muted colors.  He has enjoyed the bounciness of the
ride to the barn.  He also enjoys jumping off into wagon and seizing "the clover and
timothy" (165), both of which have sweet smells.  Can you imagine how much fun it is to
roll around in these?  This is an intensely physical experience.  Whitman is glorying in
the pleasure of hard work and play.
