Dear Prickly Porky seems to have been born old. He reminds me of a little old man who is half sad, half timid, and altogether wistfull. He cannot throw his qullls, as has been said of him, but, when attacked, rolls himself in a ball, every wonderful quill on end, so that he resembles an over-ripe chestnut burr. Note the Baby Polky in the lower right-hand corner.
