one o'clock
When desirability had been successfully dealt with , ten or more words were happily disposed of , then came another poser in the form of ` physiognomical , ' and the groans which greeted it foretold its fate . `` What does it _ mean _ , anyway , Miss Preston ? '' asked one girl . `` Well , there is more than one way of telling you its meaning , but I believe in simple explanations , so I will say , that when you all rush off to the cloak-room at one o'clock that it would be well for you to observe carefully the expression upon the other girl 's face when you throw down her hat and coat in your eagerness to get your own first . You will then , doubtless , have an excellent opportunity to form a correct idea of the meaning of physiognomical . Then you may come and tell me whether you consider her character an angelic or impish one . '' How well Miss Preston was aware of their besetting sins , and how shrewdly did she use them to their undoing .
