ence, that you will here find an inexhaustible fund of 

 novelty. For more than twenty years my attention has 

 been directed to them, and during most of my summer 

 walks my eyes have been employed in observing their

 metals a ; in others she lights up the dazzling radiance of 

 polished gems b . Some she has decked with what looks
