"Why, my father would have shot at anybody he saw climbing in. I say, are we going?"

"Yes, come along," cried d.i.c.k; and the two lads started off at a rapid pace, following in the tracks of the squire and the engineer, whose voices could be heard in a low murmur now some way ahead.

The night was glorious, and the stars were reflected in the face of the mere, whose black smooth waters seemed to form an inverted curve to complete the arch of spangled glory overhead. From far and near came the many sounds peculiar to the wild fen, while every now and then there was a solitary splash, or perhaps a loud flapping and beating of the water following closely upon the whistling and whirring of wings.

The lads had an hour's walk before them, and if they wished to keep up with those in front, an arduous and sharp walk, for it soon became evident that they were hurrying on at a great rate.

"We shall have to run directly," said d.i.c.k, after they had been going on for about twenty minutes. "Hist! what did Mr Marston say?"

"That he must have been mad to stop away from his lodgings to-night,"

whispered Tom, who had been a little in advance on the narrow path.

"Here, what's that?"

"Somebody on the mere," cried d.i.c.k excitedly. "Hi! ho!"

"Hi! ho!" came from out of the darkness where the splashing of water had been heard, accompanied by the peculiar sliding sound made by drawing a pole over the edge of a boat.

"That you, Dave?"

"Yes, Mester d.i.c.k. Hear a noise?"

"Yes. Did you?"

"Something like thunder, and it wakkened me. I think it weer a fireball."

These words were shouted as the man forced the punt along rapidly, till it was abreast of the rough road track which ran along by the edge of the mere.

"Wheer are you going?" cried Dave as soon as he came close up.

"Down to the drain-works," said Tom.

"Think it fell theer?" asked Dave.

"Yes: there was a flash of light went up."

"Hey, bud I'll come wi' you," said Dave earnestly. "I'd best land here, for I can't get much farther."

For thereabouts the track went wide of the edge of the mere, and Dave was just landing, talking volubly the while, as the squire and Mr Marston pressed on, leaving them behind, when there came another hail off the water.

"Why, it's John Warren!" cried Tom.

"What's matter?"

"We dunno, lad," shouted back Dave. "Fireball come down, I think."

"That all?" said the rabbit-catcher. "Any mischief? Don't see no fire."

"Nay, bud we don't know," replied Dave. "Squire and engineer chap's on ahead, and we're going to see. Coming?"

"Nay, I'm going back to bed again. Busy day wi' me to-morrow. I thowt someone was killed."

There was a faint glimpse of the man and his boat seen for a moment, and the water flashed in the rays of the stars as he turned; then his voice was heard muttering, and the splash of his pole came more faintly, while Dave secured and stepped out of the boat, to burst out suddenly in his grating unmusical laugh.

"He, he, he! His, hec, hac! Seems straange and disappointed, lads.

Talks as if he wanted someone killed. Now, then, come on."

By this time the squire and Mr Marston were a long way ahead, and Tom proposed a run to overtake them.

"Ay, run, lads. Keep up a trot. Dessay I shall be clost behind."

"Come along!" cried d.i.c.k; and they started off along the track, with Dave increasing his stride and seeming to skim without effort over the ground, his long wiry legs and great strength enabling him to keep up with the boys, who, whenever they looked back, found him close behind.

"You needn't mind about me, lads," he said with a chuckle; "I sha'n't be far."

They were rapidly gaining upon those in front; knowing this fact from the murmur of their voices as they kept up an animated discussion, when, all at once, it seemed as if the squire had begun to talk much more rapidly, and that Mr Marston was replying to him at a terrible rate, their voices becoming blurred and confused, as it were, when d.i.c.k realised what it meant.

"There's a party of the drain-men coming. Let's run!"

d.i.c.k was right, and five minutes after, he and his companions had joined a group gathered round Mr Marston, while Bargle, the big labourer, was talking.

"Ay, mester, we _all_ tumbled out, and went away down to the gaats as soon as we'd tumbled out, and they're all knocked down and the water in."

"Knocked down!" cried the squire.

"Ay," cried another of the men, "far as we could see; one's smashed to bits, and brickwork's all ploughed up."

"Come along!" said the engineer. "Two of you run on first and get lanthorns."

The big labourer and another went off back with a heavy trot, and the party were advancing again when a heavy step was heard behind.

"Who's that?" said Tom.

"Me, lad, me," came back in the thick hearty voice of the wheelwright.

"What's amiss?"

They told him.

"I was straange and fast asleep," he said, "and didn't hear nowt; but my missus wakkened me, and I come on."

"Ay, bud it wakkened me, neighbour," said Dave, who was busy administering to himself a pill. "I've slep' badly since I had that last touch of ager, and I thowt some un was broosting in the wall, and as soon as I jumped up and looked out, the plaace seemed alive, for all the birds in the fen were flying round and round, and you could hear their wings whistling as they flew away. I was scarred."

Half an hour later they were picking their way along the embankment at the side of the great drain, now once more filled with salt water, while when they reached the mouth, where a peculiar dank saline odour was perceptible, the two men who had been flitting before them with lanthorns like a couple of will-o'-the-wisps, went cautiously down the crumbling bank, followed by the engineer, and the mischief done was at once plain to see.

Apparently a powerful blast of powder had been placed in the hollow of the stone-work, where the mechanism for opening and closing the great sluice-gates was fixed, and the result of the explosion was a huge chasm in the stone, and one of the gates blown right off, leaving the way for the water free.

A dead silence fell upon the group as the engineer took one of the lanthorns and carefully examined the damage, the squire holding the other light, and peering forward in the darkness till the engineer climbed back to his side.

"They've managed it well," he said bitterly.
