Snuff-Sharing Werewolves

In the early 1900's a French farmer noticed two wolves approaching him.   He quickly climbed a nearby tree to avoid confronting them, and was undetected in doing so.  What he saw and heard was astonishing.  The wolves began to talk, and one of them offered some snuff (which he had stored behind his tail) to the other.   The werewolves left the snuff box behind, and the farmer was able to trace it to a local man.  The farmer was careful not to reveal any names until one of the werewolves died a natural death, and marks on his gravestone resembling those of a wolf were found.
