`` How did you know it was Phantom Mountain ? '' `` 'Cause we seen the ghost -- my partner and I -- that 's why ! '' exclaimed the man , puffing on his pipe . `` As I said , we was campin ' there , and ` long about midnight we seen somethin' tall and white , and all shimmerin ' , with a sort of yellow fire , slidin ' down the side of the mountain . It made straight for our camp . '' `` Huh ! Guess you run , did n't you , Jed ? ''
