A pouch for tobacco or money, usually made of animal skin.
Etymology: From Gaelic spliuchan, an outside pouch or receptacle for small matters.
Not really in modern use in America but I can't speak for anywhere else. It's listed in my old Webster's collegiate dictionary with a date of 1785 - I suspect because Robert Burns used it.
"When the discourse was finished, he knocked the ashes out of his pipe, replaced it in his sporran, returned the tobacco pouch or spleuchan to its owner, and joined in the prayer with decency and attention."
