          leafy.  Factors indicative of very high nutritive content.
          Hay is excellent color and free of damage.

Premium: Early maturity, i.e., pre-bloom in legumes and pre head in
         grass hays, extra leafy and fine stemmed-factors indicative of
         a high nutritive content.  Hay is green and free of damage.

Good:    Early to average maturity, i.e., early to mid-bloom in legumes
         and early head in grass hays, leafy, fine to medium stemmed,
         free of damage other than slight discoloration.

Fair:    Late maturity, i.e., mid to late-bloom in legumes, head-in
         grass hays, moderate or below leaf content, and generally
         coarse stemmed. Hay may show light damage.

         or mature head in grass hays, coarse stemmed. This category

         reports when using this category.
