Read it through once

There was dancing now on the canvas in the garden; old men pushing young girls backward in eternal graceless circles, superior couples holding each other tortuously, fashionably, and keeping in the corners—and a great number of single girls dancing individually or relieving the orchestra for a moment of the burden of the banjo or the traps. By midnight the hilarity had increased. A celebrated tenor had sung in Italian, and a notorious contralto had sung in jazz, and between the numbers people were doing “stunts” all over the garden, while happy, vacuous bursts of laughter rose toward the summer sky. A pair of stage twins, who turned out to be the girls in yellow, did a baby act in costume, and champagne was served in glasses bigger than finger-bowls. The moon had risen higher, and floating in the Sound was a triangle of silver scales, trembling a little to the stiff, tinny drip of the banjoes on the lawn.
