She rode by a place where King Coyote was adding on to the castle; but 
instead of an army of stonemasons and carpenters, the builder was a single man, 
a portly gray-bearded fellow puffing at a long slender pipe, carrying a leather 
bag on his belt. Arriving at the center of the building site, he reached into 
his bag and drew out a great seed the size of an apple and pitched it into the 
soil. By the time this man had walked back to the spiral road, a tall shaft of 
gleaming crystal had arisen from the soil and grown far above their heads, 
gleaming in the sunlight, and branched out like a tree. By the time Princess 
Nell lost sight of it around the corner, the builder was puffing contentedly 
and looking at a crystalline vault that nearly covered the lot.
