“ This [sand-dollar hunting] had become one of our rituals together, and though she would search for other varieties of shells when I was out of town or unable to see her, she would wait until I appeared on her front porch before setting off to extract these mute delicate coins from their settings in the sand. At first, we had collected only the larger specimens, but gradually as we learned what was rare and to be truly prized, we began to gather only the smallest sand dollars for our collection. Our trophies were sometimes as small as thumbnails and as fragile as contact lenses. Annie Kate collected the tiniest relics, round and cruciform and white as bone china when dried of sea water, and placed them in a glass-and-copper cricket box in her bedroom. Often we would sit together and admire the modest splendor of our accumulation. At times it looked like the coinage of a shy, diminutive species of angel. Our quest to find the smallest sand dollar became a competition between us, and as the months passed and Annie Kate grew larger with the child, the brittle, desiccated animals we unearthed from the sand became smaller and smaller. It was all a matter of training the eye to expect less. ”
