Suddenly they were conscious of an indescribable change in the place.

Neither knew what it was. It had come on in the excitement of their march into the mora.s.s--or it had come the instant they both became conscious of it. What was it? Kate turned and looked into Jack's blank face!

"I'm blessed if I know what it is, but it seems as if something had suddenly gone out of the order of things! What is it? Do you feel it; do you notice it?"

"Feel it--see it--why, it is as palpable, or, rather to speak accurately, it is as clearly absent as the color from an oil-painting, leaving mere black and white outlines."

"How besotted I am!" Jack cried; "why, I know. The sun has wholly gone, and the birds and living things have ceased to sing and move."

"That's it; could you believe that it would make such a change? Why, I thought, when we came in, the place was a temple of silence, but it was a mad world compared to this."

"Yes, and we must hurry and get out while we have daylight to help us. I take it you wouldn't care to swim the lagoon. Let us call it lagoon, for this place makes the name appropriate."

"Call it whatever you like, but don't ask me to swim it," Kate cried, pushing on.

"Ah! I have our trail," Jack cries in triumph. "By George, it is wide enough!" he added, bending over where the thick gra.s.ses were crushed and broken. "See the advantage of large feet. Now, if you had been alone, 'twould have been as hard as to trace a bird's track."

"Is that an implication that I have Chinese feet?"

"No, too literal young woman. It was meant to show you that I am very much relieved, for, 'pon my soul, I was afraid we were in a very disagreeable sc.r.a.pe."

"And you are now quite sure we are not?"

"Quite sure. Don't you want to take my arm?"

"Oh, no, thank you. I'm not at all tired. I'm used to longer walks than this."

"Longer, possibly, but not over such trying ground."

"Oh, yes. I've gone with Wesley and his friends to the lakes in the North Woods."

"Ah! I've never been there. Are they as bad travel as this?"

"Infinitely worse--Why, what was that?"

"It sounded very like the report of a pistol."

Both stopped, Kate coming quite close to the young man, who was bent over with his hand to his ear, trumpet-fashion.

"Do you--" He made a warning gesture with his hand, and motioned her to stoop among the ferns. A halloo was heard in the distance; then a response just ahead of where the two crouched in the breast-high ferns, through which the path made by their recent footsteps led. When the echoing halloo died away, a bird in the distance seemed to catch up the refrain and dwell upon the note with an exquisite, painful melody.

"Why, it's the throat interlude in the Magic Flute! How lovely it is!"

Kate whispered. "If you were my knight, I should put on you the task of caging that lovely sound for me."

The distant bird-note ceased, and then suddenly, from the bushes just ahead of them, it was caught up and answered, note for note, in a wild pibroch strain, harsher but inexpressibly moving. Jack turned to Kate, his face quite pale, and whispered:

"It in not a bird. They are negroes. I have read of these sounds. They are marauding slaves, and we must not let them see us. We must get to those thick clumps of bushes. Do you think you can remain bent until we reach them? If not, we will rest every few paces."

"Go on. I can try."

The pibroch strains still continued, rising into a mournful wail, then sinking info the soft cries of the whip-poor-will. In a few minutes the perplexed fugitives were deep in a clump of wild hawberries, invisible to any one who should pa.s.s. The strains had ceased as suddenly as they began. Then a faint hallo-o-o sounded, being answered in the bushes, as it seemed, just in front of where Jack and his companion stood; voices soon became audible farther along, ten or more paces. Motioning to Kate, Jack crept along noiselessly, and fancied he could distinguish forms through the thick screen of bushes. A voice, not a negro's, said:

"I went to the cove for you--what was the matter?"

"I had the devil's work to get through the posts. For some reason or other they're getting mighty sharp. I must be back before twelve; what's been done?"

"Well, the mokes consent to go, but they won't touch the ranch. You'll have to bring up a few hands; the fewer the better. If them d.a.m.ned feather-bed sojers wasn't there, we could do the job ourselves."

"When, does the boss get out?"

"Next week. I don't know what day. They'd pay high for him both ways."

"No, we can't nibble there. The cap'n'll pay well. That's square. We can't afford to try the other now, at any rate. Is the skiff here?"

"Yes; well, get in."

There was a plash and the-receding sound of voices. Jack darted through the screen of branches, but he could not distinguish the figures, for it was growing every instant dimmer twilight. He turned to Kate. She was at his side.

"Who were they--what were they planning? Were they soldiers?" she asked.

"Never mind them now. We must find a way out of this. Our boat can't be far off. We must follow this line of bushes until we come to the spot we left. I know I can recognize it, for there was an enormous tree fallen a few steps from the sedge bank we landed on."

It was a very toilsome journey now, obliged as they were to hug the obstinate growth of haws, wild alder, and dog roses, which tore flesh and garments in the hurried flight. They came to the dead tree finally, and Jack almost shouted in grateful relief:

"You were a true prophet, Miss Boone. You gave utterance to some Druid-like remarks as we crossed the Stygian pool. The worst your fancy painted couldn't equal what we've seen and heard."

"I have seen nothing dreadful, and I can't say that I understand very much of what we heard."

"There is some 'caper' going on to give these cut-throats a chance to get booty or something of the sort."

"They are probably rebel soldiers planning to sack the commissary."

They were in the boat now, and Jack was sending it forward by l.u.s.ty lunges against every protruding object he could get a stroke at; when these failed he managed to scull after a fashion. They found the household in consternation when they got back, but Jack gave a picturesque narrative of their escapade, omitting the encounter with the negroes which he had charged Kate to say nothing about, as it would only alarm Mrs. Atterbury. The garments of the explorers told the tale of their mishaps, and when they had clothed themselves anew supper was announced. The feast was of the lightest sort: sherbet or tea for those who liked it; fruit and crackers, honey or marmalade--a triumph in the cultivation of dyspepsia, Jack said when he first began the eating. But it was observed that the disease had no terrors for him, for he sat at the table as long as he could get any one to remain with him, and did his share in testing all the dishes. He outsat everybody that night except d.i.c.k, who never got tired of any place that brought him near his idol.

"I'm going up-stairs in a moment, Towhead. Come up after me."

d.i.c.k nodded, a gleam of delightful expectation in his eyes. He was just in the ardent period when boys love to make mysteries of very ordinary things, and Jack's _sotto voce_ command was like the hero's voice in the play, "Meet me by the ruined well when midnight strikes." He followed Jack up the wide staircase and into his own room, for greater security, as no one would think of looking for them there.

"Now, tell me all you have found out," Jack commanded as he shut the door. "Have you been among the darkys?"

"I've found out this much. The old negroes are opposed to going away or in any shape annoying their masters. The young bucks and the women are very eager to fly. It seems that some one has spread the story among them that Lincoln has sent Butler to Fort Monroe to receive all the negroes on the Peninsula. They have been a.s.sured that they are to have 'their freedom, one hundred acres of land, and an ox-team.' Where the report comes from, I can't find out; but there is some communication between here and the Union lines, I'm positive."

"Has Wesley been with the negroes again?"

"No. I have kept an eye on him all day."

"Where does he go at night?"

"The doctor has forbidden him to be in the night air for the present."
