Digging Potatoes

I'd been putting off digging potatoes for weeks. With the weather being so dry, I wasn't looking forward to digging into the ground. But yesterday was cool and sunny, and I knew I finally had to tackle the task. I was rewarded twice for the efforts. The soil, underneath the mulch, was moist and crumbling, perfect for digging around the ground for potatoes. Within an hour, I had three boxes of yellow and red potatoes. I also found a marble -- clear glass, with stripes of green, and a chip out of the side. For a moment, I paused and studied the marble, and wondered when it had been dropped on the ground and lost. Did the child look in the grass for hours for the missing orb? And, did the child mourn its loss? For how many years did the marble sit on the grass, in the ground, before I found it? What will I lose and leave behind that will have people pause and stop and wonder?
