“ When the dog attempted to be too familiar with him he rolled himself into a prickly ball, lying perfectly quiet and safe, until the dog had fully convinced himself that he had no very urgent business with such a globe of spines, and then Master Prickle would begin to unroll himself; first the snout would appear, then the head, then the feet, and the old fellow would trot off toward the pantry, grunting in the most contented fashion. Prickle was quite fond of being petted, and with his spines lying down like hair, would make a queer little sound indicative of pleasure at being caressed. ”
