RICHARD GIVES ANOTHER ILLUSTRATION OF SLEEP-WALKING.

For six or seven nights following the expedition to the watermelon patch of Mr. Batterman, Richard Grant did not "walk in his sleep." The parental solicitude of his father prompted him to set a watch for several nights; and Mr. Presby, who was still anxious to pursue his scientific investigations, slept with one eye open, that he might be in readiness to avail himself of the reappearance of the phenomenon.

The philosopher's hint that sleep-walkers are sensitive to any allusion to their infirmity, had prevented him and Mr. Grant from informing the subject of their precautions of the steps they had taken to observe his movements, and Richard was entirely unconscious that vigilant eyes were upon him while he slept, or while he ought to sleep.

But Richard was too lame and sore from the effects of his flogging to indulge again so soon in the luxury of "sleep-walking." He had not been questioned in regard to the blood upon the seats of the Greyhound, for, being asleep when the stains were made, of course he would know nothing about them. Mr. Presby explained his inactivity and want of energy upon philosophical principles, and every body seemed to be satisfied.

The salve which the sufferer applied to his wounded members healed the bruises in a few days, and he was again in condition to pursue his wonted sports and pleasures. After the lapse of a week, as the patient exhibited no further signs of the malady, the watch was discontinued; but Mr. Presby was too enthusiastic in the cause of science to abandon the case so soon. He sat up in his chamber till midnight, with his ears wide open, to catch the slightest indication of a movement on the part of his interesting subject.

Every day, Richard and Sandy met; and they never failed to renew the mutual pledges they had made to be revenged upon "Old Batterbones." The plan was discussed and amended till no further improvement could be made; and by this time Richard was so far recovered from his injuries as to enable him to take the leading part in its execution. The night was appointed for the purpose, and it was agreed that the boys should meet at a point just below Whitestone, where Richard was to take Sandy into the Greyhound, and proceed to the inlet where they had before landed.

It was a very difficult matter for Richard to get out of the house without detection. If he could succeed in opening his door, and walk through the long halls of the mansion without attracting the attention of any of its numerous inmates, he could hardly expect to unlock any of the outer doors with safety. After much reflection, he decided that it would be the better way to go out as he had gone before—over the roof of the conservatory, and down the trellis.

With the proper tools, therefore, he had removed the nails with which his father had secured the window of his chamber. He had then skilfully adjusted them, so that they appeared to be as his father had left them, though he could easily pull them out. At ten o'clock he retired as usual, but the hour of meeting was one o'clock, for the young rascals had come to the conclusion that their purpose could be better executed in the small hours of the morning, when the farmer and his man would probably be asleep.

Richard waited impatiently till he heard the clock strike twelve. There had been no noise in the chamber of Mr. Presby for some time, and he concluded that the old gentleman must be asleep. He had gone to bed as usual, in order to remove any suspicion in case he should find it necessary to act the part of the sleep-walker again. He rose and dressed himself for the expedition, using the utmost care to avoid disturbing the slumbers of the troublesome philosopher in the adjoining room.

Every thing worked to his entire satisfaction, and he was not conscious that he had made the slightest noise. The nails were removed from the window; but, though he had taken the precaution to oil the sash where it slid up and down, it creaked a little, in spite of all the care he could use. He was satisfied that the noise could not wake Mr. Presby, and he continued his operations. Leaving the window open, as a somnambulist would naturally be expected to do, he crept softly over the roof, and reached the trellis without accident.
