"I hurried back to the shop, when, as a matter of course, there was some one there; for though you may often wait all day for a customer, most likely if you get out of the way for five minutes, somebody comes. In this case it was an old clergyman, who had taken up one of the four quarto volumes, and just giving me a nod, he stood there reading for, I should think, quite a quarter of an hour, and then asked the price of the books. "`Two pounds,' I said, for I seemed to fancy that he would try to beat me down to half. But no; he pulled out his old net purse, shook out a couple of sovereigns, put two volumes under one arm and two under the other, and marched out of the shop. "`This is a curious sort of day,' I thought to myself; and somehow or other I felt so put out, that when my boy came back from an errand, after being not more than twice as long gone as he should have been, I boxed his ears--both of them--with the first and second volumes of an abridged Froissart, and then threw a pocket Nugent at him for snuffling and muttering in the corner. "For I was really put out and hurt and annoyed; and I know I once called myself a wretched old miser. "Well, a week passed, during which I had a fight with myself as to how much of these two pounds I ought to give to that poor girl if she called again. Business said I should be very generous if I gave her ten shillings; but my heart seemed to say, would it not be better to give it all? However, I could not settle it either one way or the other, even though I turned it over and over in bed at night, and let it half rob me of my rest; and when one day I was dipping into an old copy of Chaucer I had just bought, in came my fair young customer to find me as undecided as ever. "`Let me see,' I said, turning red as a found out schoolboy, `I don't think, ma'am, we made a correct settlement over those last books, which I have just sold;' and in a clumsy, awkward fashion I laid down a sovereign and a half, in a way, in fact, that looked so like offering charity, that my visitor's pale face became suffused in an instant, and she replied coldly-- "`You paid me the price you offered for the books, sir, and are evidently labouring under some mistake.' "I felt more like one found out than ever; and I believe that if my boy had been within reach I should have kicked him severely, as I blundered, and asked, in a confused, stupid way, what were her commands, when she laid half a dozen volumes before me.
