The question was put to my uncle, Mark Tregellis, whom I found seated in front of our hut as I returned one evening from a hunting excursion--it having been my duty that day to go out in search of game for our larder. Uncle Mark had just come in from his day's work, which had been that of felling the tall trees surrounding our habitation.  He and I together had cleared an acre and a half since we came to our new location.
