 There are <unk> black and white , resembling silver ore , near the village <unk> : there are likewise in the same place several stones , which in <unk> , shape , & c . , resemble <unk> , and many <unk> here afford <unk> stones of all colours . The <unk> near Loch @-@ <unk> has <unk> growing in it of different sizes and colours ; some are green on the outside , some are of a pale sky colour , and they all strike fire as well as flint : I have one of them by me , which for shape and <unk> is proper for a sword handle . Stones of a purple colour flow down the <unk> here after great rains .
