Madeleine's Rock Collection

Madeleine shows me her rock collection - pictured - and asks my favorite? I tell her the hard one (I can never resist). And how did she find the rocks, Dear Sir? "It's cuz I'm doing digging club." And when I ask, ahem, the obvious question - what does one do in digging club? - she replies matter-of-factly: "we do lots of digging." Madeleine teaches the other kids - Nicki, Jonathan, Max and Billy - "how to dig properly." And how does one do that? "They have to get really far down for it to be proper digging" (she makes a scooping motion). "You have to do it slowly so you can get more dirt." And there, my friend, you have it.
