She unfolded a worn leaf from a school geography.

“It looks as if it was only a sleep or two away, but White Antelope said it was the big ride—maybe a hundred sleeps. And lookee”—she unfolded fashion plates of several periods. “I’ve even picked out the clothes I’ll buy to put on when I get nearly to the ranch where they live. I can make camp, you know, and change my clothes, and then go walkin’ down the road carryin’ this here parasol and wearin’ this here white hat and holdin’ up this here long skirt like Teacher on Sunday.

“Won’t they be surprised when they open the door and see me standin’ on the door-step? I’ll say, ‘How do you do? I’m Susie MacDonald, your relation what’s come to visit you.’ I think this would be better than showin’ up with Running Rabbit and the pack-outfit, until I’d kind of broke the news to ’em.

“Are you sure you have no other clues—no old letters, no photographs?”
