Amazing what a 2 horse team can pull.
But before they pull you have to build the sled rails.

Once the sled is built the horses were used to 'Winch' the load on.
1892 Nestoria MI, After binding the white pine down it was off to the Worlds Fair in Chicago. A load of 50 logs 144 tons ~700,000 feet-log scale.
