‘Will the sea-nymphs punish the rash presumption of a mortal who intrudes?’ said Colonel Burr, stepping before them with a grace as invincible and assured as if he had never had any past history with either.

Mary started with a guilty blush, like a child detected in an unseemly frolic, and put her hand to her head to take off the unwonted adornments.

‘Let me protest, in the name of the graces,’ said Burr, who by that time stood with easy calmness at her side; and as he spoke he stayed her hand with that gentle air of authority which made it the natural impulse of most people to obey him. ‘It would be treason against the picturesque,’ he added, ‘to spoil that toilet so charmingly uniting the wearer to the scene.’

Mary was taken by surprise, and discomposed, as every one is who finds one’s self masquerading in attire foreign to their usual habits and character; and therefore, when she would persist in taking it to pieces, Burr found sufficient to alleviate the embarrassment of Madame de Frontignac’s utter silence in a playful run of protestations and compliments.

‘I think, Mary,’ said Madame de Frontignac, ‘that we had better be returning to the house.’

This was said in the haughtiest and coolest tone imaginable, looking at the place where Burr stood, as if there were nothing there but empty air. Mary rose to go; Madame de Frontignac offered her arm.

‘Permit me to remark, ladies,’ said Burr, with the quiet suavity which never forsook him, ‘that your very agreeable occupations have caused time to pass more rapidly than you are aware. I think you will find that the tide has risen so as to intercept the path by which you came here. You will hardly be able to get around the point of rocks without some assistance.’

Mary looked a few paces ahead, and saw, a little before them, a fresh afternoon breeze driving the rising tide high on to the side of the rocks, at whose foot their course had lain. The nook in which they had been sporting formed a part of a shelving ledge which inclined over their heads, and which it was just barely possible could be climbed by a strong and agile person, but which would be wholly inaccessible to a frail, unaided woman.

‘There is no time to be lost,’ said Burr, coolly, measuring the possibilities with that keen eye that was never discomposed by any exigency. ‘I am at your service, ladies; I can either carry you in my arms around this point, or assist you up these rocks.’ He paused and waited for their answer.
