Sniffing

 "As you know, a witch can't sniff us out because we're both seventh sons of seventh sons. But that only applies to what we call long-sniffing. So write that down. It's your first heading. Long-sniffing is sniffing out the approach of danger in advance, just as Bony Lizzie sniffed out that mob from Chipenden that burned down her house. A witch can't sniff us out that way, so that gives us the element of surprise."But it's short-sniffing that we must beware of, so write that down, too, and underline it for emphasis. Up relatively close, a witch can find out a lot about us and knows in an instant our weaknesses and strengths. And the nearer you are to a witch, the more she finds out. So always keep your distance, lad.
