On the 11th of September, 1948, a farmer was ploughing on his farm near Lac du Bonnet, roughly fifty miles northeast of Winnipeg, Manitoba. His ploughshare turned up a stone hammer and at the same time laid bare an object which, at first, he took for a piece of wood or a potato, because of its size, shape, and colour. A moment later he realized that no potato could be there, and, investigating further, discovered that the object was the end of a large bone which had been artificially shaped.
