The upper cross
bar was extended 6 inches beyond the posts at each side, and served as a
handle for guiding the queer craft. An 18-inch square board was used for
the seat of the rennwolf. It rested on the second cross-bar of the post
about 12 inches from the runners, and the forward end was supported on
legs nailed to the tie bars. On each runner back of the posts a loop of
leather was nailed, large enough to receive the toe of one shoe.
When using this odd sled one foot would rest on the runner with the toe in
the strap, and by kicking out against the snow or ice with the other foot
the rennwolf would be made to spin along at a rapid rate. Of course, when
coasting both feet would rest on the runners and the sled was steered by
an occasional side push at the right or left. Owing to the great length of
the runners the rennwolf would easily ride over uneven surfaces and thin
spots in the ice.

Ice Creepers.
In order to provide a better hold for the propelling foot, we fastened
around the toe a strap of leather, through which a number of long tacks
projected. Their sharp points would stick into the ice, and prevent the
foot from slipping.
