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."
