We picked up these fairly large stones at a lead mine where my ancestor worked; made garden markers with them. I did seven of them. I have six more rocks. Then I think I'm going to have to get more rocks. I love how they look in the flowerbeds. Free! Natural! Easy! Now this feeble old mind does not have to remember the names of everything. Well, I have to remember it at least once more so I can put it on the stone! Maybe we can find some more rock when we go river wallowing.
