Words, words, words! There's not going to be any of 'em in this drawing and besides, the Beaver seldom knows what to say anyway. They make such a buzzing in her head … so she's popped off, outside on deck, away from that galoot of a Butcher and his loquacious cronies in the main salon. She's having a breath of fresh sea air, watching the Boots and the Bellman gammon the ship's bowsprit, thinking of absolutely nothing in particular.
She is, as they say, a tabula rasa. Just the thing for an artist who's short on paper. A few quick strokes of the pen et voilà! In place of a quotidian Castor Canadensis, we now have a charming ingenue recently out of finishing school. She has imbibed all the social graces necessary for the sporting companion of any High Church Anglicans bent on Snarkicide. No more riparian galactophagogery for this lady, she's wearing the galligaskins now and she's loaded for Boojum!
In short — nurture triumphs over nature — again! Huzzah for the tabulae rasae of this world! Besides, no one likes a palimpset anyway, those snooty, nefandous know-it-alls.
