Dave Porter in the South Seas Part 19

"Oh, I'm too sleepy for fun!" murmured Roger.

"This isn't fun, it's important. Come, I say!"

Thus aroused, the senator's son rolled from his couch and hurried into his clothing. In a few minutes both boys had their shoes and caps on, and along the hallway they sped, and down the back stairs. The door below was unlocked, but closed. Soon they were out in the rear yard of the Hall, and there they beheld Shadow Hamilton walking slowly in the direction of the boathouse.

"Who is it?" whispered Roger.

"It is Shadow. He is walking in his sleep. I want to find out where he is going and what he'll do."

"Humph! This certainly is interesting," answered the senator's son.

"Whatever you do, Roger, don't arouse him, or there may be an accident,"

cautioned Dave. "Let him go his own way."

"But he may hurt himself, anyway."

"No, he won't. A sleep-walker can walk a slack wire, if he tries it, and never tumble. Haven't you heard of them walking on the ridge pole of a house? I have."

"I've read about such things. And I know they say you mustn't arouse them. He is going into the boathouse!"

The chums ran forward and reached the doorway of the boathouse just as Shadow Hamilton was coming out. The somnambulist had a pair of oars, and he stepped to the edge of the dock and untied one of the boats and leaped in.

"I must find them!" they heard the youth mutter to himself. "I must find them and bring them back!"

"Did you hear that?" asked Roger. "What is he talking about?"

"That remains to be found out. Come, let us follow him," returned Dave.

They procured two pairs of oars, and were soon in another boat and pulling behind Shadow Hamilton. The boy who was asleep seemed to possess supernatural strength, and they had no easy time of it keeping up with him. His course was up the Leming River, past Robbin's Point, and then into a side stream that was rather narrow, but almost straight for a distance of two miles.

"Do you know where this stream leads to?" questioned Roger.

"I do not."

"Almost to the old castle that we visited last winter on our skates, the day we caught that robber and saved Billy Dill. The river makes half a dozen twists and turns before the castle is reached, but this is a direct route and much shorter."

"Can it be possible that Shadow is going to the old castle?" queried the country boy.

"I'm sure I don't know. We'll learn pretty soon."

As my old readers know, the place referred to was a dilapidated structure of brick and stone which had been erected about the time of the Revolutionary War. It set back in a wilderness of trees, and was given over largely to the owls and to tramps. It belonged to an unsettled estate that had gone into litigation, and there was no telling if it would ever be rebuilt and occupied in a regular way.

It was dark under the trees, but by pulling close to the boat ahead, Dave and Roger managed to keep Shadow Hamilton in sight. As soon as the somnambulist came near to the castle he ran his boat up the bank, leaped ash.o.r.e, and stalked toward the building.

"He has disappeared!" cried Roger, softly.

"I see him," answered Dave. "Come!" and he led the way into the old structure and to the very rooms where the encounter with the robber and with Billy Dill had occurred.

Scarcely daring to breathe, they watched Shadow move around in an uncertain way, touching this object and that, and opening and shutting several closet doors, and even poking into the chimney-place.

"Gone! gone! gone!" they heard him mutter. "What shall I do? What shall I do?" And he gave a groan.

Five minutes pa.s.sed and the sleep-walker left the castle and hurried to his boat. His course was now down the stream toward the Hall, and Dave and Roger followed, as before. At the dock the boats were tied up, the oars put away, and Shadow Hamilton went back to the room from which he had come. Peering in, Dave and Roger saw him undress and go to bed, just as if nothing out of the ordinary had occurred.

CHAPTER XIII

A PHOTOGRAPH OF IMPORTANCE

"I should not believe it, had I not seen it with my own eyes."

It was in this fas.h.i.+on that Roger expressed himself on the following day, when discussing the affair of the night previous with Dave. Shadow was around, as usual. He looked sleepy, but otherwise acted as if nothing out of the ordinary had happened.

"It certainly is remarkable," was Dave's comment. "The question is, what made him go to the castle? I think I know, but I cannot speak about it.

But I'll tell you what I should like to do, Roger: go up to the castle while it is daylight and take a thorough look around."

Roger was willing to do this, and the upshot of the talk was that Dave and the senator's son paid the old brick-and-stone structure a visit on the following Sat.u.r.day half-holiday, taking Phil and Ben with them. They went up in a boat by the short route, arriving there about half-past three o'clock.

There was not a soul about the deserted mansion, and the few birds flew away at their approach. It was a clear, sunny day, and they lost no time in throwing every door and window wide open, so that they might have the full benefit of the light and fresh air.

"Here is the room in which he moved around the most," remarked Roger, gazing around earnestly. "But I can't say that I see anything unusual, do you?"

They were all searching around, and after a few minutes had pa.s.sed Ben uttered a low cry and held up a small object, almost covered with dust and dirt.

"A cla.s.s pin!" cried Dave. "We must see if we can find any more of them."

It was not long before Phil came upon two pins sticking on a board of a closet. Then Roger ran into the next room and, after a short hunt, uncovered a flat pasteboard box with several more of the cla.s.s pins, each a bit tarnished by the dampness, but otherwise uninjured.

"He must have come for the pins," said Ben. "That solves the mystery of how they disappeared from Mr. Dale's possession."

"Here is a postage stamp!" e.j.a.c.u.l.a.t.ed Phil, and held it up. "It's an old German issue," he added. "And here are half a dozen others, all evidently torn from a sheet. Boys, Shadow must have taken the doctor's collection!"

Dave said nothing to this, for he had discovered a cupboard in a corner, tightly closed and with the wooden b.u.t.ton of the door missing.

He now opened the door of the cupboard with a knife.

"h.e.l.lo, what's in there?" asked Roger, who was behind him.

"Seems to be some clothing," answered Dave, and hauled forth some loose garments and also an old satchel. The garments formed part of a sailor's garb, and the satchel was marked on the bottom with the name, "William Dill."

"It's Billy Dill's missing outfit!" cried Dave, eagerly. "Oh, Roger, how glad I am that I have found this! It's the best yet!"

All the boys were interested, for they knew Dave's story and the tale of the strange sailor. As Dave ran to the light with the satchel, they crowded around him.

"I think I am fully justified in opening this grip," said the country boy. He was so agitated he could scarcely speak.
