ten o’clock
And the carpet and cow vanished together , and the boys went to bed , tired out and only too thankful that the evening at last was over . Next morning the carpet lay calmly in its place , but one corner was very badly torn . It was the corner that the cow had been tied on to . The morning after the adventure of the Persian cats , the musk-rats , the common cow , and the uncommon burglar , all the children slept till it was ten o'clock ; and then it was only Cyril who woke ; but he attended to the others , so that by half past ten every one was ready to help to get breakfast . It was shivery cold , and there was but little in the house that was really worth eating . Robert had arranged a thoughtful little surprise for the absent servants . He had made a neat and delightful booby trap over the kitchen door , and as soon as they heard the front door click open and knew the servants had come back , all four children hid in the cupboard under the stairs and listened with delight to the entrance -- the tumble , the splash , the scuffle , and the remarks of the servants .
