"I'll put a hole through the first man that tries to enter this mill. I mean what I say. Dude Moxley ain't to be trifled with."

The men hastily withdrew, first taking the precaution to remove the plank that covered the sluiceway.

"The rascal must have seen us coming up the slope in the moonlight," muttered Hocker. "I suppose he thought we had the place surrounded and every avenue of escape cut off. He's a desperate fellow, and may stand a long siege."

In truth Moxley seemed to be preparing for that very thing. He boldly drew in the shutters of the two windows that the faced the creek, and a moment later he began to roll logs about, evidently fortifying the weak places in the wall.

"That may be only a ruse," said Jeffries. "Is there any way of escape from the other side?"

"Of course there is," exclaimed the farmer. "He can easily drop from the second story window to the foot of the hill. Lend me that empty gun," he added, turning to Ned. "I'll cross the wasteway in the boat and get behind the trees a few yards up the hill. If the rascal attempts to crawl out the window I'll scare him back."

Ned handed over the gun, and the farmer departed in haste. Hocker and Jeffries moved aside and carried on a whispered conversation.

Bug was left to his own devices. He could not escape, for the removal of the plank from the sluiceway made the place literally an island. He sat down on a big stone, with his manacled hands resting on his knees. Ned was restless and heartsick, and the prolonged suspense grew more intolerable every moment. He was afraid that Moxley would vent his anger on the boys, and perhaps do them an injury.

Hocker divined the lad's thoughts.

"Don't be downhearted," he said. "Your friends are safe enough. The scoundrel won't dare to hurt them. By and by, if the siege threatens to last, we'll find a way to get them out of the mill."
