Suddenly a change passed over the tree. All the sun's warmth left the air. I knew the sky was black, because all the heat, which meant light to me, had died out of the atmosphere. A strange odour came up from the earth. I knew it, it was the odour that always precedes a thunderstorm, and a nameless fear clutched at my heart. I felt absolutely alone, cut off from my friends and the firm earth. The immense, the unknown, enfolded me. I remained still and expectant; a chilling terror crept over me. I longed for my teacher's return; but above all things I wanted to get down from that tree.
