There was one fish in particular, commonly called the electric-light fish, the scientific name being linophyrne lucifer, which had what looked like an electric light on the end of its sharp snout and a rope-like appendage under its lower jaw. It had a square mouth and sharp, curved teeth, and a look which was enough to give an ordinary mortal a chill. "We must secure a specimen of that fish," said Amos Fearless, in the sign language. "The captain and the doctor spoke about it particularly." "And also a specimen of that long, thin thing," answered Dave, pointing to what is familiarly called in Borneo the ray of fire. The ray of fire is a white fish four or five feet long and less than three inches thick. It has silver scales which flash out like fire whenever it swims quickly. Soon they had reached the half-mile limit, and the diving bell came to a standstill. Then a door in the bell was opened and they prepared to spread out a strong net with which to catch what was desired. It was by no means an easy task--indeed, the most of a diver's labors are very hard, and before the net was properly adjusted both Dave and his parent were almost winded. Then they moved the diving bell around, from one spot to another, on the lookout for the electric-light fish and the ray of fire, so called. Soon they saw one of the electric-light fish in the vicinity. They had brought some bait along, and this was tied up in the net. The monstrous fish scented the bait and came forward slowly and cautiously. He was hungry, yet he did not altogether like the appearance of the diving bell. He had never seen a live human being before, although he had feasted upon the body of more than one dead sailor, coming down with some wreck. Amos Fearless and Dave remained as motionless as statues. Nearer and nearer came the electric-light fish. The light on his snout blinked and winked in an odd fashion and was once or twice turned upon Dave and his father. Then, like a flash, the monstrous fish swept into the net after the bait. Snap! went the line attached to the top of the net, and Dave and his father began pulling the net shut with might and main. They had to work like lightning, for, feeling that something was wrong, the electric-light fish began to thrash around at a lively rate. The net swept to and fro as the fish darted hither and thither in its efforts to escape. Bang! Up against the diving bell came net and fish with a shock that threatened to shiver the glass into a million fragments. "Shove away!" motioned Amos Fearless to his son, and Dave caught hold of a rod to which the net was fastened and the net was placed at a distance from the bell. At last the wonderful electric-light fish was a prisoner in the net. It still continued to thrash around, and fearful that he might break loose in spite of the strength of the net, Amos Fearless signaled to those on the ship to haul up the prize.
