interesting occupation for a leisure hour to sit with a lens 

 in hand sifting the sand distinguishing here a fragment 

 of shell and there a piece of a sea-urchin's spine, here a 

 remnant of an acorn-shell's rampart and there a Fora-

 different samples of sugar ; they are stages in the process 

 of reduction towards that lowest common denominator 

 which we call the sand of the seashore.
