The indians have surrounded the fort and are preparing an attack. The indian chief calls up his generals and asks them what thye think they should do. As he is doing this, the best tracker in the tribe rushes up. "Stop,", he yells, "I think they're going to come out and charge us!"
All the indians troop down to the road in front of the fort and ask the tracker if he can give them anymore information. The tracker puts his ear to the ground...
"Yep, they've got 60-70 mounted cavalry, most of them have rifles"
The chief tries not to look impressed at this amazing feat and asks if the tracker can tell anything else.
With his ear back to the ground the tracker says "Ooh, hang on... there's another 40 or so with pistols"
The chief is gobsmacked at the detail and asks for more.
The tracker bends down again, ear to the floor. "Uh-oh... they've got a couple of cannon as well... they're loading them with grapeshot as we speak... then they've gathered maybe 200 troops most of them armed with swords but a quite a few have pistols... the new revolver types..."
On this information the chief pulls his braves back and hides while the calvalry charges out of the fort. As they pass by the chief is amazed to see that everything the tracker said was true.
He summons the tracker to his teepee that night and tells him that he is giving the tracker his daughter to marry, he was being made part of the chief's family and would one day be chief himself, with wealth and riches and prosperity. All because the tracker's incredible hearing had saved many indian braves' lives.
"My hearing?", says the tracker, "I was just looking under the gate!"
