Scotts' teams manhauled sledges, two or three men
would be attached to the sledge with canvas harnesses and then lean
forwards to pull. It's not so bad as it appears and a huge amount
of equipment can be carried in this manner. While not as efficient as
travelling with a dog team, there are compensations, mainly that dogs
don't need to be considered when stopping and it is very easy to unclip
and suddenly become completely unencumbered.
