n.— «Other mystery words I found while perusing my great-grandfather’s papers were “orehano” and “sleeper.” “I haven’t seen any of Wise’s men lately and I have been helping myself to some of his Orehanos and have also caught several sleepers lately” was part of a letter written to Sanford on November 10th, 1912, by Brad’s grandfather, Albert Gatlin, who was managing the Sanford livestock.…Sleepers were calves that had been ear-marked but not yet branded.» —by Albert Gatlin Nov. 10, 1912.
