iam happy to be here.
i need to know the origin of (Barking up the wrong tree
i looked for i ,but i fined only
The allusion is to hunting dogs barking at the bottom of trees where they (mistakenly) think their quarry is hiding.
The earliest known printed citation is James Hall's, 'Legends of the West', 1833:
"You are barking up the wrong tree, Johnson."
if ther i s more or at least other way to explain i hope to know.
There is no more to it than that. For example, setters, which are supposed to flush birds out of trees, can, when young, get the wrong tree and they will literally bark at an empty tree hoping to get the bird out.
