Something, however, occurred to change their plans, and it was the latter part of June when they left home for their trip to the North.  They had a pleasant voyage, making few pauses by the way, and reached their destination on Monday, the second day of July.

It was early in the evening when the Dolphin neared the White City; the little ones were already in bed and sweetly sleeping, but all the others had gathered on deck to catch the first glimpse of the fairy-like scene.  They had passed the mouth of the Chicago River and were steaming on down the lake.

“Oh, papa, what is that?” asked Grace, pointing to a bright light in the water.

“A lighted buoy,” he replied; “a spar buoy with an incandescent lamp of one hundred candle power.  It is a wrought-iron cage at the end of a spar which is held in place by a heavy cast-iron anchor.  You will see another presently, for there are thirteen between the river and the White City.”

“To warn vessels to keep off shoals?” she asked.

“Yes,” he said, and went on to explain how the electrical current was supplied, winding up with a promise to take her, and anyone else who wished to go, to the Electrical Building to gaze upon its wonders, and also for a ride in the electric launches.  “But,” he added, “I think there is nothing you will enjoy more than the sight of the electric lights which you will get presently in the Peristyle and the Court of Honor.”

“Oh, I am very eager to see it all, papa!” she exclaimed.

“As we all are,” said Lulu.

“Well, my dears, I think we can all go there at once and spend an hour or two; all but the little ones, who can be left in the care of their nurse.”  He turned enquiringly toward his wife and her mother as he spoke.

“Oh, yes,” said Violet; “they will not be likely to wake, and Agnes will take good care of them.”

“I think we are all probably ready to accept your invitation with pleasure, captain,” Elsie said.  “Surely none of us are fatigued—­unless with lack of exercise.”

“No, surely not,” remarked Mr. Dinsmore, “and I, as well as Grace, am eager to see the beauties of that much talked of Court of Honor.”

“I think we will find some other objects worthy of our attention before we reach even the Peristyle,” remarked Captain Raymond.

“Oh, yes!” exclaimed Lulu, “there is another of those lights.”

“I am so glad you brought us in the yacht, captain,” said Evelyn; “for we can start out at once to see the sights—­not being in the least fatigued with our long journey.”

“And we have already a beautiful view of water and sky,” remarked Grandma Elsie; “those sunset clouds are certainly lovelier than any work of man’s hands.”

“Yes, mamma; and they are beautifully reflected in the water,” said Violet.

“But such things can be seen at home,” Rosie remarked in a sprightly tone, “and I propose to give my particular attention to such as are to be found only in this part of the world and at the present time.”
