His power ceases , as does that of all evil things , at the coming of the day . Only at certain times can he have limited freedom . If he be not at the place whither he is bound , he can only change himself at noon or at exact sunrise or sunset . These things are we told , and in this record of ours we have proof by inference . Thus , whereas he can do as he will within his limit , when he have his earth-home , his coffin-home , his hell-home , the place unhallowed , as we saw when he went to the grave of the suicide at Whitby ; still at other time he can only change when the time come . It is said , too , that he can only pass running water at the slack or the flood of the tide .
