“It’s a lightning-rod staircase, Mrs. Warren,” explained Henry Burns. “I use it sometimes after ten o’clock, for that is my bedtime, you know. Mrs. Carlin—good soul—sends me off to bed regularly at that hour, no matter what is going on; and so I have to make use of it occasionally.”

Mrs. Warren shook her head doubtfully.

“You shouldn’t do it, Henry,” she said. “Although I know it is hard for a strong, healthy boy to go off to bed every night at ten o’clock. Well, that comes of being too strict, I suppose,—but do look out and don’t break your neck. It’s a bad night to be climbing around.”

“Don’t worry about Henry Burns, mother,” said Arthur. “He wouldn’t do it, if he wasn’t forced to it,—and he knows how to take care of himself, if anybody does.”

“Well, good night,” said Henry Burns. “And don’t forget, I hold my reception to-morrow night; and I extend to Tom and Bob a special invitation to be present.” And, with a knowing glance at George Warren, Henry Burns took his departure.

As the boys went off to bed that night, George Warren explained to them that on the next night, the occasion being an entertainment in place of the regular Wednesday night hop at the hotel, he and Henry Burns had planned a joke on Colonel Witham, in which they were all to take part, and, with this prospect in view, they dropped asleep.

In the meantime Henry Burns, arriving at the hotel, and having learned by previous experience that a lock on a rear door of the old part of the hotel, which was not connected with the new by any door, could be manipulated with the aid of a thin blade of a jack-knife, crept up to the garret by way of a rickety pair of back stairs, and from thence emerged upon the roof through a scuttle. Then, carefully making his way along the ridge-pole to where the new part joined the old, he climbed a short distance up a lightning-rod, to the roof of the new part.

This was a large roof, nearly flat. He walked across, about midway of the building, to where another rod, fastened at the top to a chimney, came up. Clinging to this, Henry Burns disappeared over the edge of the roof, found a resting-place for his foot on a projection which was directly over his own window, and then lowered himself, like an acrobat, down the rod to a veranda. Raising the window directly beside the rod, he slipped inside, closed it softly, and in a few minutes more was abed and sound asleep.

While all Southport slept, the storm spent its force, and toward morning gradually subsided. In the place of the beating rain there stole up through the islands, in the early morning hours, great detached banks of fog,—themselves like strange, white islands,—which shut out the bay from the shore. They lay heavy over the water, and, as the boisterous seas gradually gave way to the long, smooth waves that rolled in without breaking, one might have fancied that the fog, itself, had a depressing and tranquillizing influence upon the sea.

Yet old fishermen would have ventured out then, without fear, for there were signs, that might be read by the weather-wise, that a light west wind was soon to be stirring that would scatter the fog at its first advance, and sweep it back out to sea.
