Turning the snow over with his iron-tipped staff, the Doctor found that the colouring matter measured nine feet deep. He pointed this out to his companions, that they might have some idea of the enormous number of these tiny mushrooms in a layer extending so many miles.

This phenomenon was none the less strange for being explained, for red is a colour seldom seen in nature over any considerable area. The reflection of the sun's rays upon it produced the most peculiar effect, lighting up men, and animals, and rocks with a fiery glow, as if proceeding from some flame within. When the snow melted it looked like blood, as the red particles do not decompose. It seemed to the travellers as if rivulets of blood were running among their feet.

The Doctor filled several bottles with this precious substance to examine at leisure, as he had only had a glimpse of the Crimson Cliffs in Baffin's Bay.

This Field of Blood, as he called it, took three hours to get over, and then the country resumed its usual aspect.
