farther on” only instead of farther on in space, it
     was farther on in time, over the horizon of the years ahead instead of the far horizon

    She was still the pioneer girl and she could understand Manly's love of the land through
     its appeal to herself.
    “Oh, well,” Laura sighed, summing up her idea of the situation in a saying of her Ma's:
     “We'll always be farmers, for what is bred in the bone
    
    
     will
    
    
     come out in the flesh.” And then Laura smiled, for Manly was coming from the barn and he was singing:
    “You talk of the mines of Australia, They've wealth in red gold, without doubt; But, ah!
     there is gold in the farm, boys If only you'll shovel it out.”
    The oval glass bread plate Laura and Manly bought for their first Christmas together. The
     plate survived the fire and was found among Rose Wilder Lane's things after her death. It
     is now at the Laura Ingalls Wilder Home Association in Mansfield, Missouri, for all
     visitors to see.
