All eyes now perceived a dark hole in the roof, a round hole exactly in the middle of the shining dome. And as they gazed the dark hole became light. And they saw above them a white shining disk like a very large and very bright moon. It was the light of day.
'Some one has opened the trap-door,' said Lucy. 'The Ingots always closed their treasure-vaults with trap-doors.'
The bright disk was obscured; confused shapes broke its shining roundness. Then another disk, small and very black appeared in the middle of it; the black disk grew larger and larger and larger. It was coming down to them. Slowly and steadily it came; now it reached the level of the dome, now it hung below it; down, down, down it came, past the level of their eager eyes and splashed in the water close by the ship. It was a large empty bucket. The rope which held it was jerked from above; the bucket dipped and filled and was drawn up again slowly and steadily till it disappeared in the hole in the roof.
'Quick,' said the parrot, 'get the ship exactly under the hole, and next time the bucket comes down you can go up in it.'
'This is out of the Arabian Nights, I think,' said Lucy, when the yacht was directly under the hole in the roof. 'But who is it that keeps on opening the books? Somebody must be pulling Polistopolis down.'
'The Pretenderette, I shouldn't wonder,' said Philip gloomily. 'She isn't the Deliverer, so she must be the Destroyer. Nobody else can get into Polistarchia, you know.'
'There's me.'
'Oh, you're Deliverer too.'
'Thank you,' said Lucy gratefully. 'But there's Helen.'
'She was only on the Island, you know; she couldn't come to Polistarchia. Look out!'
