o'clock
`` Do n't let 's bother , '' said Marjorie ; `` they 'll know we 're just out playing somewhere , and we 'll be back by breakfast time , -- it is n't six o'clock yet . '' `` You wo n't want any breakfast after all this stuff , '' said Molly , whose appetite was not as robust as the Maynards ' . '' ` Deed we will ! '' declared King ; `` this little snack is all right for six o'clock , but I have an engagement at eight in the dining-room . '' They trudged along to the boathouse , and , as they might have expected , found it locked . `` I 'll get it , '' said Molly ; `` I 'm the swiftest runner , and I know where the key hangs in Carter 's workshop . '' King watched Molly admiringly as she flew across the grass , her long , thin , black legs flinging out behind her with incredible quickness .
