Such was the scene I looked on till, completely covering my head up in a buffalo-robe, I closed my eyes.  I was awakened by finding an unusual weight above me.  I threw my arms about, when down came a cold shower on my face and clearing my eyes I could just see the snow on every side, while my body was completely covered up.  I was perfectly warm, however, and felt no inclination to get out of my cosy bed to brush the snow away.  I drew my robe again over my head; being well assured that Uncle Donald would arouse us if there was any risk of our being completely covered up.  How much longer I had slept I could not tell, when I was once more awakened by a terrific howling, yelping, the barking of dogs, the trampling and snorting of horses, followed by the shouts and shrieks of our men.
