CHAPTER 8.
A BANQUET UNDER WATER The palaces of the mermaids were all aglow with lights as they approached them, and Trot was amazed at the sight.
"Where do the lamps come from ?" she asked their guide wonderingly.
"They are not lamps, my dear," replied Merla, much amused at this suggestion.

"We use electric lights in our palaces and have done so for thousands of years--long before the earth people knew of electric lights." "But where do you get 'em ?" inquired Cap'n Bill, who was as much astonished as the girl.
"From a transparent jellyfish which naturally emits a strong and beautiful electric light," was the answer.

"We have many hundreds of them in our palaces, as you will presently see." Their way was now lighted by small, phosphorescent creatures scattered about the sea gardens and which Merla informed them were hyalaea, or sea glowworms.

But their light was dim when compared to that of the electric jellyfish, which they found placed in clusters upon the ceilings of all the rooms of the palaces, rendering them light as day.

Trot watched these curious creatures with delight, for delicately colored lights ran around their bodies in every direction in a continuous stream, shedding splendid rays throughout the vast halls.
A group of mermaids met the visitors in the hall of the main palace and told Merla the queen had instructed them to show the guests to their rooms as soon as they arrived.
