“In one fountain,” said Gypsy, catching on with enthusiasm, “and lemonade crystals in the other.”

They went out to spend their pound. While they were absent, the Piccadilly Flower-Girls came and got to work. In a few minutes the Square was a garden of roses. Roses red and white, yellow and pink, garlanded the stone balustrades opposite the National Gallery and wreathed the basins of the fountains; arches of roses bloomed up the steps; the Weatherhouse was smothered in Crimson Ramblers; Dorothy Perkins climbed from the foot of the Nelson Column to the top of Nelson’s head, the base was mounded deep in moss, and every lion crouched in a temple of standards. Their work was barely accomplished when Mrs. Green arrived buried in balloons. They were gas balloons of every colour, and each was anchored with a fairy lamp, so that when she let them go they hung in chains and patterns of light fifteen feet in air. The other Moonlighters were now appearing in full force. The Punch-and-Judy Man set up his theatre between the fountains, Tonio’s striped and painted Hokey-Pokey booth was established in one corner, the Strawberry Girl had her great fruit-baskets in another. Jeremy, with an assortment of his brightest wares, turned the Weatherhouse into a Penny Toyshop. The Organ-Man and his barrel-organ took the middle of the Square, where there was plenty of room for dancing. The Muffin-and-Crumpet Man walked round and round and round ringing his bell. They told him that for once he was out of season, but the Night Watchman said that the moon was blue to-night, so that anything could happen for once.

By the time Gypsy and Ginger returned, laden with packets of Sherbert and Lemonade Powder, the party was ready.

“Oh!” cried Ginger.

She dropped her parcels and dashed from attraction to attraction; flew one of Jeremy’s windmills round the Square, tasted a strawberry, ate half a hokey-pokey, rang the muffin-bell in Toby’s ear, stuck a rose in her smock, and seizing Gypsy’s hands danced him three times round the barrel-organ.

Then they all turned their attention to the fountains, and just as the sherbert got really fizzing the Evening Newsboy appeared with the children.

Not many parties begin in full swing, but Gypsy’s and Ginger’s did. The moment the children of London saw Trafalgar Square, a dream of balloons and roses under the blue moon, they began to laugh; and for two hours, whether they were dancing to the organ music as only London Children can dance: or watching Punch thwack Judy as only Punch can thwack: or eating crumpets, and strawberries, and free ice-creams: or besieging the Weatherhouse for Jeremy’s free toys, or lying on their stomachs over the fountains with their faces in the sherbert: or playing Touch-Stone with Lily, Rose and Jessamine around the Column: they never stopped laughing. When the Taxi-Man appeared astride of Snow-Flame, and put him through his loveliest circus-tricks below the fairy lights, their laughter was louder than ever. And when Gypsy, inspired by the sound of it, painted this sign in luminuous paint on the National Gallery:

THERE IS NO TRUTH IN THE RUMOUR
THAT CHILDREN’S PARTIES WILL BE HELD IN
TRAFALGAR SQUARE ONCE A WEEK

their laughter was so loud that it was heard from Land’s End to John o’ Groats. It was so loud that it was heard by the Policeman in the Strand.

He blew his whistle.
