He was threatening the doctor, with his fist in his face, by this time. The doctor struck out suddenly and stretched the ruffian on the ground. Potter dropped his knife, and exclaimed:

"Here, now, don't you hit my pard!" and the next moment he had grappled with the doctor and the two were struggling with might and main, trampling the grass and tearing the ground with their heels. Injun Joe sprang to his feet, his eyes flaming with passion, snatched up Potter's knife, and went creeping, catlike and stooping, round and round about the combatants, seeking an opportunity. All at once the doctor flung himself free, seized the heavy headboard of Williams' grave and felled Potter to the earth with it—and in the same instant the half-breed saw his chance and drove the knife to the hilt in the young man's breast. He reeled and fell partly upon Potter, flooding him with his blood, and in the same moment the clouds blotted out the dreadful spectacle and the two frightened boys went speeding away in the dark.

Presently, when the moon emerged again, Injun Joe was standing over the two forms, contemplating them. The doctor murmured inarticulately, gave a long gasp or two and was still. The half-breed muttered:

"THAT score is settled—damn you."

Then he robbed the body. After which he put the fatal knife in Potter's open right hand, and sat down on the dismantled coffin. Three—four—five minutes passed, and then Potter began to stir and moan. His hand closed upon the knife; he raised it, glanced at it, and let it fall, with a shudder. Then he sat up, pushing the body from him, and gazed at it, and then around him, confusedly. His eyes met Joe's.

"Lord, how is this, Joe?" he said.

"It's a dirty business," said Joe, without moving.

"What did you do it for?"

"I! I never done it!"

"Look here! That kind of talk won't wash."

Potter trembled and grew white.

"I thought I'd got sober. I'd no business to drink to-night. But it's in my head yet—worse'n when we started here. I'm all in a muddle; can't recollect anything of it, hardly. Tell me, Joe—HONEST, now, old feller—did I do it? Joe, I never meant to—'pon my soul and honor, I never meant to, Joe. Tell me how it was, Joe. Oh, it's awful—and him so young and promising."

"Why, you two was scuffling, and he fetched you one with the headboard and you fell flat; and then up you come, all reeling and staggering like, and snatched the knife and jammed it into him, just as he fetched you another awful clip—and here you've laid, as dead as a wedge til now."

"Oh, I didn't know what I was a-doing. I wish I may die this minute if I did. It was all on account of the whiskey and the excitement, I reckon. I never used a weepon in my life before, Joe. I've fought, but never with weepons. They'll all say that. Joe, don't tell! Say you won't tell, Joe—that's a good feller. I always liked you, Joe, and stood up for you, too. Don't you remember? You WON'T tell, WILL you, Joe?" And the poor creature dropped on his knees before the stolid murderer, and clasped his appealing hands.

"No, you've always been fair and square with me, Muff Potter, and I won't go back on you. There, now, that's as fair as a man can say."

"Oh, Joe, you're an angel. I'll bless you for this the longest day I live." And Potter began to cry.

"Come, now, that's enough of that. This ain't any time for blubbering. You be off yonder way and I'll go this. Move, now, and don't leave any tracks behind you."

Potter started on a trot that quickly increased to a run. The half-breed stood looking after him. He muttered:

"If he's as much stunned with the lick and fuddled with the rum as he had the look of being, he won't think of the knife till he's gone so far he'll be afraid to come back after it to such a place by himself—chicken-heart!"

Two or three minutes later the murdered man, the blanketed corpse, the lidless coffin, and the open grave were under no inspection but the moon's. The stillness was complete again, too.

CHAPTER X

THE two boys flew on and on, toward the village, speechless with horror. They glanced backward over their shoulders from time to time, apprehensively, as if they feared they might be followed. Every stump that started up in their path seemed a man and an enemy, and made them catch their breath; and as they sped by some outlying cottages that lay near the village, the barking of the aroused watch-dogs seemed to give wings to their feet.

"If we can only get to the old tannery before we break down!" whispered Tom, in short catches between breaths. "I can't stand it much longer."

Huckleberry's hard pantings were his only reply, and the boys fixed their eyes on the goal of their hopes and bent to their work to win it. They gained steadily on it, and at last, breast to breast, they burst through the open door and fell grateful and exhausted in the sheltering shadows beyond. By and by their pulses slowed down, and Tom whispered:

"Huckleberry, what do you reckon'll come of this?"

"If Doctor Robinson dies, I reckon hanging'll come of it."

"Do you though?"

"Why, I KNOW it, Tom."

Tom thought a while, then he said:

"Who'll tell? We?"

"What are you talking about? S'pose something happened and Injun Joe DIDN'T hang? Why, he'd kill us some time or other, just as dead sure as we're a laying here."

"That's just what I was thinking to myself, Huck."

"If anybody tells, let Muff Potter do it, if he's fool enough. He's generally drunk enough."

Tom said nothing—went on thinking. Presently he whispered:

"Huck, Muff Potter don't know it. How can he tell?"

"What's the reason he don't know it?"

"Because he'd just got that whack when Injun Joe done it. D'you reckon he could see anything? D'you reckon he knowed anything?"

"By hokey, that's so, Tom!"

"And besides, look-a-here—maybe that whack done for HIM!"

"No, 'taint likely, Tom. He had liquor in him; I could see that; and besides, he always has. Well, when pap's full, you might take and belt him over the head with a church and you couldn't phase him. He says so, his own self. So it's the same with Muff Potter, of course. But if a man was dead sober, I reckon maybe that whack might fetch him; I dono."

After another reflective silence, Tom said:

"Hucky, you sure you can keep mum?"

"Tom, we GOT to keep mum. You know that. That Injun devil wouldn't make any more of drownding us than a couple of cats, if we was to squeak 'bout this and they didn't hang him. Now, look-a-here, Tom, less take and swear to one another—that's what we got to do—swear to keep mum."

"I'm agreed. It's the best thing. Would you just hold hands and swear that we—"

"Oh no, that wouldn't do for this. That's good enough for little rubbishy common things—specially with gals, cuz THEY go back on you anyway, and blab if they get in a huff—but there orter be writing 'bout a big thing like this. And blood."

Tom's whole being applauded this idea. It was deep, and dark, and awful; the hour, the circumstances, the surroundings, were in keeping with it. He picked up a clean pine shingle that lay in the moon-light, took a little fragment of "red keel" out of his pocket, got the moon on his work, and painfully scrawled these lines, emphasizing each slow down-stroke by clamping his tongue between his teeth, and letting up the pressure on the up-strokes:

"Huck Finn and Tom Sawyer swears they will keep mum about This and They wish They may Drop down dead in Their Tracks if They ever Tell and Rot."

Huckleberry was filled with admiration of Tom's facility in writing, and the sublimity of his language. He at once took a pin from his lapel and was going to prick his flesh, but Tom said:

"Hold on! Don't do that. A pin's brass. It might have verdigrease on it."
