 I saw the marriage of the trapper in the open air in the far
         west, the bride was a red girl,
 Her father and his friends sat near cross-legged and dumbly
         smoking, they had moccasins to their feet and large
         thick blankets hanging from their shoulders,        
 On a bank lounged the trapper, he was drest mostly in skins,
         his luxuriant beard and curls protected his neck, he held
         his bride by the hand,
 She had long eyelashes, her head was bare, her coarse straight
         locks descended upon her voluptuous limbs and reach'd
         to her feet.
