From the text:
She had a box filled with catalogues, illustrated books and stumps of pencils. It gave her great joy to play the teacher to Sidda. She made him squat on the floor with a pencil between his fingers and a catalogue in front of him. She had another pencil and a catologue and commanded, "Now write." And he had to try and copy whatever she wrote in the pages of her catologue. She knew two or three letters of the alphabet and could draw a kind of cat and crow. But none of these could Sidda even remotely copy. She said, examining his effort, "Is ths how I have drawn the crow? Is this how I have drawn the B?" She pitied him, and redoubled her efforts to teach him. But that good fellow, though an adept at controlling the moon, was utterly incapable of plyng the pencil.
