Read it through once

Neither Esther nor William knew how to waltz, but they tumbled round the room, enjoying themselves immensely. In the polka and mazurka they got on better; and there were quadrilles and lancers in which the gentlemen joined, and all were gay and pleasant; even Sarah's usually sour face glowed with cordiality when they joined hands and raced round the men standing in the middle. In the chain they lost themselves as in a labyrinth and found their partners unexpectedly. But the dance of the evening was Sir Roger de Coverley, and Esther's usually sober little brain evaporated in the folly of running up the room, then turning and running backwards, getting into her place as best she could, and then starting again. It always appeared to be her turn, and it was so sweet to see her dear William, and such a strange excitement to run forward to meet young Mr. Preston, to curtsey to him, and then run away; and this over and over again.
