It was a judgment unlike anything in her own nature of which she was aware, excepting the measurement of ingredients for a pudding. So they sat, all engrossed, while the kettle began to sing and the desired steam to pour from the spout, clouding the scullery. The only sound that arose was the gurgling of Pa Blanchard's pipe (for he was what is called in Kennington Park a wet smoker). He sat remembering something or pondering the insufficiency of news. Nobody ever knew what he thought about in his silences. It was a mystery over which the girls did not puzzle, because they were themselves in the habit of sitting for long periods without speech. Pa's broodings were as customary to them as the absorbed contemplativeness of a baby. "Give him his pipe," as Jenny said; "and he'll be quiet for hours--till it goes out. _Then_ there's a fuss! My word, what a racket! Talk about a fire alarm!" And on such occasions she would mimic him ridiculingly, to diminish his complaints, while Emmy roughly relighted the hubble-bubble and patted her father once more into a contented silence. Pa was to them, although they did not know it, their bond of union. Without him, they would have fallen apart, like the outer pieces of a wooden boot-tree. For his sake, with all the apparent lack of sympathy shown in their behaviour to him, they endured a life which neither desired nor would have tolerated upon her own account. So it was that Pa's presence acted as a check and served them as company of a meagre kind, although he was less interesting or expansive than a little dog might have been. When Jenny went out to the scullery carrying her hat, after sweeping the scraps she had declined back into the old draper's cardboard box which amply contained such treasures and preserved them from dust, Emmy, now quite quiet again, continued to sit by the fire, staring at the small glowing strip that showed under the door of the kitchen grate. Every now and then she would sigh, wearily closing her eyes; and her breast would rise as if with a sob. And she would sometimes look slowly up at the clock, with her head upon one side in order to see the hands in their proper aspect, as if she were calculating. ii From the scullery came the sound of Jenny's whistle as she cheerily held the hat over the steam. Pa heard it as something far away, like a distant salvationists' band, and pricked up his ears; Emmy heard it, and her brow was contracted. Her expression darkened. Jenny began to hum: "'Oh Liza, sweet Liza, If you die an old maid you'll have only yourself to blame ...'"
