We wouldn't go five miles without bumping into a fellow countryman. Come on now, isn't it time for our sudden departure from Captain Nemo?"

"No, no, Ned," I replied in a very firm tone. "Let's ride it out, as you seafaring fellows say. The Nautilus is approaching populated areas. It's going back toward Europe, let it take us there. After we arrive in home waters, we can do as we see fit. Besides, I don't imagine Captain Nemo will let us go hunting on the coasts of Malabar or Coromandel as he did in the forests of New Guinea."

"Well, sir, can't we manage without his permission?"

I didn't answer the Canadian. I wanted no arguments. Deep down, I was determined to fully exploit the good fortune that had put me on board the Nautilus.

After leaving Keeling Island, our pace got generally slower. It also got more unpredictable, often taking us to great depths. Several times we used our slanting fins, which internal levers could set at an oblique angle to our waterline. Thus we went as deep as two or three kilometers down but without ever verifying the lowest depths of this sea near India, which soundings of 13,000 meters have been unable to reach. As for the temperature in these lower strata, the thermometer always and invariably indicated 4 degrees centigrade. I merely observed that in the upper layers, the water was always colder over shallows than in the open sea.

On January 25, the ocean being completely deserted, the Nautilus spent the day on the surface, churning the waves with its powerful propeller and making them spurt to great heights. Under these conditions, who wouldn't have mistaken it for a gigantic cetacean? I spent three-quarters of the day on the platform. I stared at the sea. Nothing on the horizon, except near four o'clock in the afternoon a long steamer to the west, running on our opposite tack. Its masting was visible for an instant, but it couldn't have seen the Nautilus because we were lying too low in the water. I imagine that steamboat belonged to the Peninsular & Oriental line, which provides service from the island of Ceylon to Sidney, also calling at King George Sound and Melbourne.

At five o'clock in the afternoon, just before that brief twilight that links day with night in tropical zones, Conseil and I marveled at an unusual sight.

It was a delightful animal whose discovery, according to the ancients, is a sign of good luck. Aristotle, Athenaeus, Pliny, and Oppian studied its habits and lavished on its behalf all the scientific poetry of Greece and Italy. They called it "nautilus" and "pompilius." But modern science has not endorsed these designations, and this mollusk is now known by the name argonaut.

Anyone consulting Conseil would soon learn from the gallant lad that the branch Mollusca is divided into five classes; that the first class features the Cephalopoda (whose members are sometimes naked, sometimes covered with a shell), which consists of two families, the Dibranchiata and the Tetrabranchiata, which are distinguished by their number of gills; that the family Dibranchiata includes three genera, the argonaut, the squid, and the cuttlefish, and that the family Tetrabranchiata contains only one genus, the nautilus. After this catalog, if some recalcitrant listener confuses the argonaut, which is acetabuliferous (in other words, a bearer of suction tubes), with the nautilus, which is tentaculiferous (a bearer of tentacles), it will be simply unforgivable.

Now, it was a school of argonauts then voyaging on the surface of the ocean. We could count several hundred of them. They belonged to that species of argonaut covered with protuberances and exclusive to the seas near India.

These graceful mollusks were swimming backward by means of their locomotive tubes, sucking water into these tubes and then expelling it. Six of their eight tentacles were long, thin, and floated on the water, while the other two were rounded into palms and spread to the wind like light sails. I could see perfectly their undulating, spiral-shaped shells, which Cuvier aptly compared to an elegant cockleboat.
