“But we?—What time or thought had we for his troubles? _We were free!_ In lightning leaps, in curving spurts, in crazy zig-zags—whooping, shrieking with delight, we sped for home and the open sea! “That is all of my story and I will now, as I promised last night, try to answer any questions you may ask about the sea, on condition that I am set at liberty as soon as you have done.” _The Doctor:_ “Is there any part of the sea deeper than that known as the Nero Deep—I mean the one near the Island of Guam?” _The Fidgit:_ “Why, certainly. There’s one much deeper than that near the mouth of the Amazon River. But it’s small and hard to find. We call it ‘The Deep Hole.’ And there’s another in the Antarctic Sea.” _The Doctor:_ “Can you talk any shellfish language yourself?” _The Fidgit:_ “No, not a word. We regular fishes don’t have anything to do with the shellfish. We consider them a low class.” _The Doctor:_ “But when you’re near them, can you hear the sound they make talking—I mean without necessarily understanding what they say?” _The Fidgit:_ “Only with the very largest ones. Shellfish have such weak small voices it is almost impossible for any but their own kind to hear them. But with the bigger ones it is different. They make a sad, booming noise, rather like an iron pipe being knocked with a stone—only not nearly so loud of course.” _The Doctor:_ “I am most anxious to get down to the bottom of the sea—to study many things. But we land animals, as you no doubt know, are unable to breathe under water. Have you any ideas that might help me?” _The Fidgit:_ “I think that for both your difficulties the best thing for you to do would be to try and get hold of the Great Glass Sea Snail.” _The Doctor:_ “Er—who, or what, is the Great Glass Sea Snail?” _The Fidgit:_ “He is an enormous salt-water snail, one of the winkle family, but as large as a big house. He talks quite loudly—when he speaks, but this is not often. He can go to any part of the ocean, at all depths because he doesn’t have to be afraid of any creature in the sea. His shell is made of transparent mother-o’-pearl so that you can see through it; but it’s thick and strong. When he is out of his shell and he carries it empty on his back, there is room in it for a wagon and a pair of horses. He has been seen carrying his food in it when traveling.” _The Doctor:_ “I feel that that is just the creature I have been looking for. He could take me and my assistant inside his shell and we could explore the deepest depths in safety. Do you think you could get him for me?”
