six o'clock
On this were a troupe of entertainers called The Pierrots . They all wore funny white suits , with little black pompons bobbing all over them . They sang amusing songs , played on cymbals and other instruments , did some clever acrobatic work , and for a half-hour entertained the guests who stood about on the grass , or sat on camp chairs to watch them . At six o'clock the guests all took leave , and the great procession of vehicles again appeared on the driveway . Mrs. Cromarty and Mrs. Hartley received their good-byes , and Patty and Mabel invited a number of the young people to remain to dine and spend the evening . `` Though I 'm sure we ca n't eat any dinner , after that very satisfying tea , '' said Grace Meredith , as she accepted the invitation . In the evening they all went out on the lake for a moonlight row .
