“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 for 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-bespangled sky, while her light irrigated the smooth and shiny sides and wings and backs of the Blue-Bottle-Flies with a peculiar and trivial splendor, while all Nature cheerfully responded to the cerulean and conspicuous circumstances.

In many long-after years, the four little travellers looked back to that evening as one of the happiest in all their lives; and it was already past midnight when—­the sail of the boat having been set up by the Quangle-Wangle, the tea-kettle and churn placed in their respective positions, and the Pussy-Cat stationed at the helm—­the children each took a last and affectionate farewell of the Blue-Bottle-Flies, who walked down in a body to the water’s edge to see the travellers embark.

As a token of parting respect and esteem, Violet made a courtesy quite down to the ground, and stuck one of her few remaining parrot-tail feathers into the back hair of the most pleasing of the Blue-Bottle-Flies; while Slingsby, Guy, and Lionel offered them three small boxes, containing, respectively, black pins, dried figs, and Epsom salts; and thus they left that happy shore forever.

Overcome by their feelings, the four little travellers instantly jumped into the tea-kettle, and fell fast asleep.  But all along the shore, for many hours, there was distinctly heard a sound of severely-suppressed sobs, and of a vague multitude of living creatures using their pocket-handkerchiefs in a subdued simultaneous snuffle, lingering sadly along the walloping waves as the boat sailed farther and farther away from the Land of the Happy Blue-Bottle-Flies.

Nothing particular occurred for some days after these events, except that, as the travellers were passing a low tract of sand, they perceived an unusual and gratifying spectacle; namely, a large number of Crabs and Crawfish—­perhaps six or seven hundred—­sitting by the water-side, and endeavoring to disentangle a vast heap of pale pink worsted, which they moistened at intervals with a fluid composed of lavender-water and white-wine negus.
