claw. As cars drive by, many of the walnuts get processed, that is, run over and stripped of their yellow-green husks. My father used to do this--put walnuts in the driveway and drive over them until the husks were off. What was left were the walnuts, with meats safe within an iron-hard shell. We may have tried breaking some open with a hammer, then toiled to pick out what small portions of nut were inside. Most of them remained for years in a big tin can in the basement. I think of that toil and trouble every time I buy a bag of nuts, all perfectly cleaned.
Breaking apart some of the nuts collected on Linden with a hammer proved very easy, though the meats were only black papery remains--nothing edible. Clearly, more gathering and testing is needed.
