slowed down to a walk

It struck him as curious that he could run at all on feet so frozen that he could not feel
them when they struck the earth and took the weigh. of his body. He seemed to himself to
skim along above the surface, and to have no connection with the earth. Somewhere he had
once seen a winged Mercury, and he wondered if Mercury felt as he felt when skimming over
the earth.
His theory of running until he reached camp and the boys had one flaw in it: he lacked the
endurance. Several times he stumbled, and finally he tottered, crumpled up, and fell. When
he tried to rise, he failed. He must sit and rest, he decided, and next time he would merely
walk and keep on going. As he sat and regained his breath, he noted that he was feeling
quite warm and comfortable He was not shivering, and it even seemed that a warm glow had
come to his chest and trunk. And yet, when he touched his nose or cheeks, there was no
sensation. Running would not thaw them out. Nor would it thaw out his hands and feet. Then
the thought came to him that the frozen portions of his body must be extending. He tried to
keep this thought down, to forget it, to think of something else; he was aware of the
panicky feeling that it caused, and he was afraid of the panic. But the thought asserted
itself, and persisted, until it produced a vision of his body totally frozen. This was too
much, and he made another wild run along the trail. Once he slowed down to a walk, but the
thought of the freezing extending itself made him run again.
