"He must have assistants, of course," Tug replied, "and I shall make application to enter his service as soon as I arrive. I want to get even with Uncle Ponsonboy."

Tug locked up a laugh again with a sharp click of the lock, and his scalp hurried back to its place on learning that it was a false alarm.

"I want to get a note from him to this effect: 'Dear Tug: For the sake of old acquaintance, send me a drop of water.' Whereupon I will take my iron pen in hand, and reply: 'Uncle Ponsonboy: Drink your tears.' Then I will instruct one of my devilish assistants to lock him up, and never let him see the cheerful light of the fires again. As the door closes, I will say to him, as I now say to you,—Good-night."

Tug and Silas walked toward the hills, and Dorris and his wife toward the town, but the shadow no longer followed them; it had disappeared.

In case the shadow came back that night to prowl around The Locks, and peer in at the windows, it found a determined-looking man on guard, carrying a wicked-looking gun.

Had the eyes of the shadow followed the feet of the man, it would have noted that they walked around the stone wall at regular intervals, and that they stopped occasionally, as if listening; it would have seen them strolling leisurely away at the first approach of dawn, carrying the gun and Tug's burly body with them.


CHAPTER XVIII.

THE RISE IN THE RIVER.

The rain had been falling at intervals for weeks, and the sluggish river, which usually crawled at the foot of the town in quiet submission, had become a dangerous torrent. Long since out of its banks, its waters poured through the bottoms with an angry roar, and at night those who gathered on the brink in the town to mark its steady rising could hear cries of distress from the heavy timber, the firing of guns, and other alarms.
