"Get up and run, or you'll freeze!" He tried to rise, but failed to regain his feet, and collapsed.
Thereupon Addison and Thomas laid hold of him, and lifted him to his feet by main strength.
"Now run!" they cried.

"Run before your clothes freeze stiff!" The man seemed lethargic--I suppose from the deadly chill.

He made an effort to move his feet, as they bade him, but fell flat again; and by that time his clothes were stiffening.
"He will freeze to death!" Addison cried.

"We must put him on his sled and get him home!" Thereupon we picked him up like a log of wood, and laid him on his horse-sled.
"But he will freeze before we can get this old lame horse home with him!" exclaimed Thomas.

"Better take him to our camp over there." Addison thought so, too, and seizing the reins and whip, started for the shore.
