On the following day, a little after four o’clock, Adam set out for Mercy.

He was home just as the clocks were striking six.  He was pale and upset, but otherwise looked strong and alert.  The old man summed up his appearance and manner thus: “Braced up for battle.”

“Now!” said Sir Nathaniel, and settled down to listen, looking at Adam steadily and listening attentively that he might miss nothing—even the inflection of a word.

“I found Lilla and Mimi at home.  Watford had been detained by business on the farm.  Miss Watford received me as kindly as before; Mimi, too, seemed glad to see me.  Mr. Caswall came so soon after I arrived, that he, or someone on his behalf, must have been watching for me.  He was followed closely by the negro, who was puffing hard as if he had been running—so it was probably he who watched.  Mr. Caswall was very cool and collected, but there was a more than usually iron look about his face that I did not like.  However, we got on very well.  He talked pleasantly on all sorts of questions.  The nigger waited a while and then disappeared as on the other occasion.  Mr. Caswall’s eyes were as usual fixed on Lilla.  True, they seemed to be very deep and earnest, but there was no offence in them.  Had it not been for the drawing down of the brows and the stern set of the jaws, I should not at first have noticed anything.  But the stare, when presently it began, increased in intensity.  I could see that Lilla began to suffer from nervousness, as on the first occasion; but she carried herself bravely.  However, the more nervous she grew, the harder Mr. Caswall stared.  It was evident to me that he had come prepared for some sort of mesmeric or hypnotic battle.  After a while he began to throw glances round him and then raised his hand, without letting either Lilla or Mimi see the action.  It was evidently intended to give some sign to the negro, for he came, in his usual stealthy way, quietly in by the hall door, which was open.  Then Mr. Caswall’s efforts at staring became intensified, and poor Lilla’s nervousness grew greater.  Mimi, seeing that her cousin was distressed, came close to her, as if to comfort or strengthen her with the consciousness of her presence.  This evidently made a difficulty for Mr. Caswall, for his efforts, without appearing to get feebler, seemed less effective.  This continued for a little while, to the gain of both Lilla and Mimi.  Then there was a diversion.  Without word or apology the door opened, and Lady Arabella March entered the room.  I had seen her coming through the great window.  Without a word she crossed the room and stood beside Mr. Caswall.  It really was very like a fight of a peculiar kind; and the longer it was sustained the more earnest—the fiercer—it grew.  That combination of forces—the over-lord, the white woman, and the black man—would have cost some—probably all of them—their lives in the Southern States of America.  To us it was simply horrible.  But all that you can understand.  This time, to go on in sporting phrase, it was understood by all to be a ‘fight to a finish,’ and the mixed group did not slacken a moment or relax their efforts.  On Lilla the strain began to tell disastrously.  She grew pale—a patchy pallor, which meant that her nerves were out of order.  She trembled like an aspen, and though she struggled bravely, I noticed that her legs would hardly support her.  A dozen times she seemed about to collapse in a faint, but each time, on catching sight of Mimi’s eyes, she made a fresh struggle and pulled through.

“By now Mr. Caswall’s face had lost its appearance of passivity.  His eyes glowed with a fiery light.  He was still the old Roman in inflexibility of purpose; but grafted on to the Roman was a new Berserker fury.  His companions in the baleful work seemed to have taken on something of his feeling.  Lady Arabella looked like a soulless, pitiless being, not human, unless it revived old legends of transformed human beings who had lost their humanity in some transformation or in the sweep of natural savagery.  As for the negro—well, I can only say that it was solely due to the self-restraint which you impressed on me that I did not wipe him out as he stood—without warning, without fair play—without a single one of the graces of life and death.  Lilla was silent in the helpless concentration of deadly fear; Mimi was all resolve and self-forgetfulness, so intent on the soul-struggle in which she was engaged that there was no possibility of any other thought.  As for myself, the bonds of will which held me inactive seemed like bands of steel which numbed all my faculties, except sight and hearing.  We seemed fixed in an impasse.  Something must happen, though the power of guessing was inactive.  As in a dream, I saw Mimi’s hand move restlessly, as if groping for something.  Mechanically it touched that of Lilla, and in that instant she was transformed.  It was as if youth and strength entered afresh into something already dead to sensibility and intention.  As if by inspiration, she grasped the other’s band with a force which blenched the knuckles.  Her face suddenly flamed, as if some divine light shone through it.  Her form expanded till it stood out majestically.  Lifting her right hand, she stepped forward towards Caswall, and with a bold sweep of her arm seemed to drive some strange force towards him.  Again and again was the gesture repeated, the man falling back from her at each movement.  Towards the door he retreated, she following.  There was a sound as of the cooing sob of doves, which seemed to multiply and intensify with each second.  The sound from the unseen source rose and rose as he retreated, till finally it swelled out in a triumphant peal, as she with a fierce sweep of her arm, seemed to hurl something at her foe, and he, moving his hands blindly before his face, appeared to be swept through the doorway and out into the open sunlight.

“All at once my own faculties were fully restored; I could see and hear everything, and be fully conscious of what was going on.  Even the figures of the baleful group were there, though dimly seen as through a veil—a shadowy veil.  I saw Lilla sink down in a swoon, and Mimi throw up her arms in a gesture of triumph.  As I saw her through the great window, the sunshine flooded the landscape, which, however, was momentarily becoming eclipsed by an onrush of a myriad birds.”

By the next morning, daylight showed the actual danger which threatened.  From every part of the eastern counties reports were received concerning the enormous immigration of birds.  Experts were sending—on the............
