Continuity mistake: When Stan and Ollie arrive at Brushwood Gulch, they show Mickey Finn the deed they've got for Mary Roberts, and it has a couple of holes in it from where Stan has been keeping it in his shoe; Ollie even unfurls it to show the camera it's got holes. But in every other shot after that, whenever the deed is shown, it's got no holes in it whatsoever and is perfectly clean.
