Hi, I'm wondering if anyone can help me with a few expressions having to do with the Australian Gold Rush of the 1850s: "a red-striped plain plaid dress" means a simple plaid dress with red stripes? "save her from a crab hole" (does this have to do with mining?) "has got the pluck to jump the golden hole" (someone receives a reward for testifying against two men) "a surveyed town" "struck bung on the gutter" and: "it would be a lesson not only for diggers, but also for other commissioners and officials, the troops and traps, Camp employees and townies... Thank you!!!
