I'm reading Passin' Through,the Lost Treasures edition. I found what seems to be a case of getting something backwards. It's when he's hiding out under the ponderosa tree. He has his horses that he had retrieved from where he'd left them at the beginning of the story. Page 164, about halfway down, the paragraph starts with:
When I had rested I would pack my horse, saddle the others, and ride for Parrott City.
One would assume it should say: When I had rested I would saddle my horse, pack the others, and ride for Parrott City. Obviously no reason to saddle more than one horse. Not sure if that was a brain fart that LL had when writing, or it got mixed up somewhere else along the way.
