A few paces away, a monstrous, meter-high sea spider was staring at me with beady eyes, poised to spring at me. Although my diving suit was heavy enough to protect me from this animal's bites, I couldn't keep back a shudder of horror. Just then Conseil woke up, together with the Nautilus's sailor. Captain Nemo alerted his companion to this hideous crustacean, which a swing of the rifle butt quickly brought down, and I watched the monster's horrible legs writhing in dreadful convulsions.

This encounter reminded me that other, more daunting animals must be lurking in these dark reaches, and my diving suit might not be adequate protection against their attacks. Such thoughts hadn't previously crossed my mind, and I was determined to keep on my guard. Meanwhile I had assumed this rest period would be the turning point in our stroll, but I was mistaken; and instead of heading back to the Nautilus, Captain Nemo continued his daring excursion.

The seafloor kept sinking, and its significantly steeper slope took us to greater depths. It must have been nearly three o'clock when we reached a narrow valley gouged between high, vertical walls and located 150 meters down. Thanks to the perfection of our equipment, we had thus gone ninety meters below the limit that nature had, until then, set on man's underwater excursions.
