useful to a variety of people in a variety of ways

With the bag slung over her arm, and rattling as she waddled away, she waddled to the door, where she stopped to inquire if she should leave us a lock of her hair. 'Ain't I volatile?' she added, as a commentary on this offer, and, with her finger on her nose, departed.
Steerforth laughed to that degree, that it was impossible for me to help laughing too; though I am not sure I should have done so, but for this inducement. When we had had our laugh quite out, which was after some time, he told me that Miss Mowcher had quite an extensive connexion, and made herself useful to a variety of people in a variety of ways. Some people trifled with her as a mere oddity, he said; but she was as shrewdly and sharply observant as anyone he knew, and as long-headed as she was short-armed. He told me that what she had said of being here, and there, and everywhere, was true enough; for she made little darts into the provinces, and seemed to pick up customers everywhere, and to know everybody. I asked him what her disposition was: whether it was at all mischievous, and if her sympathies were generally on the right side of things: but, not succeeding in attracting his attention to these questions after two or three attempts, I forbore or forgot to repeat them. He told me instead, with much rapidity, a good deal about her skill, and her profits; and about her being a scientific cupper, if I should ever have occasion for her service in that capacity.
She was the principal theme of our conversation during the evening: and when we parted for the night Steerforth called after me over the banisters, 'Bob swore!' as I went downstairs.
I was surprised, when I came to Mr. Barkis's house, to find Ham walking up and down in front of it, and still more surprised to learn from him that little Em'ly was inside. I naturally inquired why he was not there too, instead of pacing the streets by himself? I shook him warmly by the hand when he had put it away again - for that was more satisfactory to me than saying anything - and we walked up and down, for a minute or two, in silence. The door opened then, and Peggotty appeared, beckoning to Ham to come in. I would have kept away, but she came after me, entreating me to come in too. Even then, I would have avoided the room where they all were, but for its being the neat-tiled kitchen I have mentioned more than once. The door opening immediately into it, I found myself among them before I considered whither I was going.
The girl - the same I had seen upon the sands - was near the fire. She was sitting on the ground, with her head and one arm lying on a chair. I fancied, from the disposition of her figure, that Em'ly had but newly risen from the chair, and that the forlorn head might perhaps have been lying on her lap. I saw but little of the girl's face, over which her hair fell loose and scattered, as if she had been disordering it with her own hands; but I saw that she was young, and of a fair complexion. Peggotty had been crying. So had little Em'ly. Not a word was spoken when we first went in; and the Dutch clock by the dresser seemed, in the silence, to tick twice as loud as usual. Em'ly spoke first.
