Read it through once

Beside the crag the heath was very deep: when I lay down my feet were buried in it; rising high on each side, it left only a narrow space for the night-air to invade. I folded my shawl double, and spread it over me for a coverlet; a low, mossy swell was my pillow. Thus lodged, I was not, at least at the commencement of the night, cold.
