People who have only seen London on Coronation Day, or Lord Mayor’s Show Day, or on the day when the Ambassador of Calamiane is given the Freedom of the City, do not really know of what she is capable in the way of festival. All these occasions are foreseen and dress-rehearsed. The costume is provided in advance, and it is trusted that the spirit, as well as the body, may inhabit it on the day. But when the time comes it is usually about some business of its own; for in spite of the newspapers the spirit is not the body’s house-dog. It doesn’t come when it’s whistled for. Its breed is tameless.

But when it springs out of its wilds it does in an hour what Committees cannot do in six months. Only those who saw Trafalgar Square on the night of Gypsy and Ginger’s party know what the spirit of London can do in an hour.

The Evening Newsboy spread the rumour of the party with the swiftness and ubiquity of evening news. He had the newsboy’s art of subdividing a single rumour into a flight of swallows. Before midnight every slum in the city knew there was to be a party amongst the fountains of Trafalgar Square.

Gypsy and Ginger sat on the floor of the Weatherhouse making staircases of their two-hundred-and-forty pennies, and consulted how to spend them to the best advantage. They had quite forgotten their intention of spending them on railway tickets to Sussex.

“Which do you think the children would like best?” asked Gypsy. “Presents or supper?”

“Presents and supper,” said Ginger.

“It won’t run to both, darling. The guests will come in their thousands.”

“But think of a whole pound.”

“I know, but all the same,” said Gypsy. He was really the practical one of the two. “If we decided on presents, a lot could be done with beads and marbles.”

“If they had supper, we could give them farthing buns,” said Ginger. “For a pound you can get a thousand farthing buns, more or less, I’m never sure which. But if there are thousands of children—.”

“What about a Conjuror?” suggested Gypsy. “You ought to be able to buy quite a good Conjuror for a pound?”

“No,” said Ginger, “we can be our own conjurors. And I want the children to have something that will really go round without giving out, and I’ve thought of what it is.”

“Well?” said Gypsy.

“Sherbert,” said Ginger. “Packets and packets of it. In the fountains.”

“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.

In a trice the London Police were on the alert.
