"Don't let us fire till we get up to the rock; then rest a moment, and it will be hard if we don't hit one of them.  If we miss, we'll see what Surley can do for us."  Jerry nodded his agreement to this proposal, and crouching down, we crept on till we reached the rock.  For an instant we waited to recover breath, then we lifted up our rifles and rested them on a ledge of the rock.  It would be impossible to have got a better aim.  Crack-- crack--we both fired.  Off scampered the herd up the mountain.
