Don't know about the piece of bone but did begin my angling career terrorizing cutthroat in small creeks with a willow switch, 4 foot piece of string, a # 8 hook and can of worms dug in the garden. And yes the can holding those worms was one of those flat tobacco cans (thanks to an uncle that rolled his own) that fit in our shirt pockets.

Great times and remember those hooks being pretty precious and if snagged considerable effort was spend to retrieve that hook.
