standing broad upon their granite base, like the heavy columns of Tuscan architecture. Why had our incomprehensible guide led us to the bottom of this submarine crypt? I was soon to know. After descending a rather sharp declivity, our feet trod the bottom of a kind of circular pit. There Captain Nemo stopped, and with his hand indicated an object I had not yet perceived. It was an oyster of extraordinary dimensions, a gigantic tridacne, a goblet which could have contained a whole lake of holy water, a basin the breadth of which was more than two yards and a half, and consequently larger than that ornamenting the saloon of the Nautilus. I approached this extraordinary mollusk. It adhered by its byssus to a table of granite, and there, isolated, it developed itself in the calm waters of the grotto I estimated the weight of this tridacne at 600 pounds. Such an oyster would contain thirty pounds of meat; and one must have the stomach of a Gargantua to demolish some dozens of them.
Captain Nemo was evidently acquainted with the existence of this bivalve, and seemed to have a particular motive in verifying the actual state of this tridacne. The shells were a little open; the captain came near, and put his dagger between to prevent them from closing; then with his hand he raised the membrane with its fringed edges, which formed a cloak for the creature. There, between the folded plaits, I saw a loose pearl, whose size equaled that of a cocoanut. Its globular shape, perfect clearness, and admirable luster made it altogether a jewel of inestimable value. Carried away by my curiosity I stretched out my hand to seize it, weigh it, and touch it, but the captain stopped me, made a sign of refusal, and quickly withdrew his dagger, and the two shells closed suddenly. I then understood Captain Nemo's intention. In leaving this pearl hidden in the mantle of the tridacne, he was allowing it to grow slowly. Each year the secretions of the mollusk would add new concentric circles. I estimated its value at £500,000 at least.
After ten minutes Captain Nemo stopped suddenly. I thought he had halted previously to returning. No; by a gesture he bade us crouch beside him in a deep fracture of the rock, his hand pointed to one part of the liquid mass, which I watched attentively.
