The snow continued to fall so heavily, that Uncle Donald decided to remain where we were, or rather to form another camp more under shelter of the trees.  To proceed with the horses would have been almost impossible, and he therefore settled to send them back and to prepare the sleighs and snow-shoes for the rest of our journey.  A sleigh is simply a thin board, ten feet long and about a foot broad, turned up at one end.  The baggage is secured to it by leathern thongs.
