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.



I forgot about Skidding the logs out of the cut, Checkout this rig:



BTW..... In the picture above and below, the horses on the right.. have some style of a HAME FASTENER attached on the left side of the padded collars.
