He feared, then, to see her too often.
She turned toward the wall to smile--for there was in this smile such an expression of triumph that this smile alone would have betrayed her.
She allowed, therefore, half an hour to pass away; and as at that moment all was silence in the old castle, as nothing was heard but the eternal murmur of the waves--that immense breaking of the ocean--with her pure, harmonious, and powerful voice, she began the first couplet of the psalm then in great favor with the Puritans: "Thou leavest thy servants, Lord, To see if they be strong; But soon thou dost afford Thy hand to lead them on." These verses were not excellent--very far from it; but as it is well known, the Puritans did not pique themselves upon their poetry.
While singing, Milady listened.

The soldier on guard at her door stopped, as if he had been changed into stone.

Milady was then able to judge of the effect she had produced.
Then she continued her singing with inexpressible fervor and feeling.

It appeared to her that the sounds spread to a distance beneath the vaulted roofs, and carried with them a magic charm to soften the hearts of her jailers.

It however likewise appeared that the soldier on duty--a zealous Catholic, no doubt--shook off the charm, for through the door he called: "Hold your tongue, madame! Your song is as dismal as a 'De profundis'; and if besides the pleasure of being in garrison here, we must hear such things as these, no mortal can hold out." "Silence!" then exclaimed another stern voice which Milady recognized as that of Felton.
