Upon seeing the space which had been obscured by the shadow of the boat’s hulk, Ulysses found the bottom of the sea so near that he almost believed that he could touch it with the point of his oar.  The rocks were like glass.  In their interstices and hollows the plants were moving like living creatures, and the little animals had the immovability of vegetables and stones.  The boat appeared to be floating in the air and athwart the liquid atmosphere that wraps this abysmal world, the fish hooks were dangling, and a swarm of fishes was swimming and wriggling toward its encounter with death.

It was a sparkling effervescence of yellowing flames, of bluish backs and rosy fins.  Some came out from the caves silvered and vibrant as lightning flashes of mercury; others swam slowly, big-bellied, almost circular, with a golden coat of mail.  Along the slopes, the crustaceans came scrambling along on their double row of claws attracted by this novelty that was changing the mortal calm of the under-sea where all follow and devour, only to be devoured in turn.  Near the surface floated the medusae, living parasols of an opaline whiteness with circular borders of lilac or red bronze.  Under their gelatinous domes was the skein of filaments that served them for locomotion, nutrition and reproduction.

The fishermen had only to pull in their lines and a new prisoner would fall into their boat.  Their baskets were filling up so fast that the Triton and his nephew grew tired of this easy fishing....  The sun was now near the height of its curve, and every wavelet was carrying away a bit of the golden band that divided the blue immensity.  The wood of the boat appeared to be on fire.

“We’ve earned our day’s pay,” said the Triton, looking at the sky and then at the baskets.  “Now let’s clean up a little bit.”

And stripping off his clothing, he threw himself into the sea.  Ulysses saw him descend from the center of the ring of foam opened by his body, and could gauge by it the profundity of that fantastic world composed of glassy rocks, animal plants and stone animals.  As it went down, the tawny body of the swimmer took on the transparency of porcelain.  It appeared of bluish crystal—­a statue made of a Venetian mirror composition that was going to break as soon as it touched the bottom.

Like a god he was passing through the deeps, snatching plants out by the roots, pursuing with his hands the flashes of vermilion and gold hidden in the cracks of the rocks.  Minutes would pass by; he was going to stay down forever; he would never come up again.  And the boy was beginning to think uneasily of the possibility of having to guide the bark back to the coast all alone.  Suddenly the body of white crystal began taking on a greenish hue, growing larger and larger, becoming dark and coppery, until above the surface appeared the head of the swimmer, who, spouting and snorting, was holding up all his submarine plunder to the little fellow.
