“Where do we go now?” asked Rose, as she helped her mother by carrying a package in one hand and holding to Margy with the other.  Rose was a real “mother’s helper” that day.

“We go on the boat now,” said Daddy Bunker.  “And I want you children to be very careful.  We are going to ride on the boat all night, and we shall be in New York in the morning.”

“Shall we sleep on the boat?” asked Laddie.

“Yes, we’ll have cute little beds to sleep in,” said Mother Bunker.

A half hour later they were on one of the big Fall River boats that make nightly trips between New York and the Massachusetts city.  The Bunkers were shown to their state-rooms.  They had three large apartments, with several bunks, or beds, in each one, so there would be plenty of room.

They had their supper on the boat, and then they went out on deck in the evening.  There were many sights new and strange to the children, and they looked eagerly at each one.  Then it grew dark, and it was decided that the time had come for little folks to “turn in,” and go to sleep.

Laddie, who with Russ and his father shared a room together, was looking from the window of the stateroom, out into the dark night, when he suddenly cried out: 

“Oh, there’s going to be a big thunder storm!  I just saw the flash of lightning!”

“Are you sure it was lightning?” asked Mr. Bunker with a smile.  “I didn’t hear any thunder.”

“There it is again!” cried Laddie, and this time a ray of bright, white light shone in the window, full in Laddie’s face.

CHAPTER IV

A MIX-UP

“That isn’t lightning,” said Russ, who had come to the window of the stateroom to stand beside his brother and look out.

“’Tis, too!” insisted Laddie, as another flash came.  “It’s lightning, and maybe it’ll set our boat on fire, and then we can’t go to Cousin Tom’s an’ dig for gold!  So there!”

Mr. Bunker, who was opening a valise in one corner of the room, getting out the boys’ pajamas for the night, had not seen the light shining in the window, but had seen the glare of it on the wall.

“’Tisn’t lightning at all!” declared Russ again.

“How do you know it isn’t?” asked Laddie.

“’Cause lightning flashes are a different color,” said Russ.  “And, besides, they don’t stay still so long.  Look, Daddy, this one is peeping right in our window like a light from Aunt Jo’s automobile!”

Mr. Bunker turned in time to see the bright flash of light come in through the window, and then it seemed to stay in the room, making it much brighter than the light from the electric lamps on the wall.

“Of course that isn’t lightning!” said Mr. Bunker.  “That’s a search-light from some ship.  Come on out on deck, boys, and we’ll see it.”

The bright glare was still in the room, but it did not flare up as lightning would have done, and there were no loud claps of thunder.
