By-and-by the Four Children came to a country where there were no houses, but only an incredibly innumerable number of large bottles without corks, and of a dazzling and sweetly susceptible blue colour. Each of these blue bottles contained a Blue-Bottle Fly, and all of these interesting animals live continually together in the most copious and rural harmony, nor perhaps in many parts of the world is such perfect and abject happiness to be found. Violet, and Slingsby, and Guy, and Lionel, were greatly struck with this singular and instructive settlement, and having previously asked permission of the Blue-Bottle-Flies (which was most courteously granted), the Boat was drawn up to the shore and they proceeded to make tea in front of the Bottles; but as they had no tea-leaves, they merely placed some pebbles in the hot water, and the Quangle-Wangle played some tunes over it on an Accordion, by which of course tea was made directly, and of the very best quality.

The Four Children then entered into conversation with the Blue-Bottle-Flies, who discoursed in a placid and genteel manner, though with a slightly buzzing accent, chiefly owing to the fact that they each held a small clothes-brush between their teeth which naturally occasioned a fizzy extraneous utterance.
‘Why,’ said Violet, ‘would you kindly inform us, do you reside in bottles? and if in bottles at all, why not rather in green or purple, or indeed in yellow bottles?’
To which questions a very aged Blue-Bottle-Fly answered, ‘We found the bottles here all ready to live in, that is to say, our great-great-great-great-great-grandfathers did, so we occupied them at once. And when the winter comes on, we turn the bottles upside down, and consequently rarely feel the cold at all, and you know very well that this could not be the case with bottles of any other colour than blue.’
‘Of course it could not;’ said Slingsby, ‘but if we may take the liberty of inquiring, on what do you chiefly subsist?’
‘Mainly on Oyster-patties,’ said the Blue-Bottle-Fly, ‘and, when these are scarce, on Raspberry vinegar and Russian leather boiled down to a jelly.’
‘How delicious!’ said Guy.
To which Lionel added, ‘Huzz!’ and all the Blue-Bottle-Flies said ‘Buzz!’
At this time, an elderly Fly said it was the hour of the Evening-song to be sung; and on a signal being given all the Blue-Bottle-Flies began to buzz at once in a sumptuous and sonorous manner, the melodious and mucilaginous sounds echoing all over the waters, and resounding across the tumultuous tops of the transitory Titmice upon the intervening and verdant mountains, with a serene and sickly suavity only known to the truly virtuous. The Moon was shining slobaciously from the star-bespringled sky, while her light irrigated the smooth and shiny sides and wings and backs of the Blue-Bottle-Flies with a peculiar and trivial splendour, while all nature cheerfully responded to the cerulaean and conspicuous circumstances.
