"But some have to be."

"No; going to see them, I mean."

"Well, I don't know; they play a very important part in the proceedings, and in a way they are heroes, for wherever they go with us they share our danger. I heard quite a lot of interesting things about them."

At this moment they were approaching a part of the route which separated them for a while from the popular plaudits. In the forefront was a deep archway, and beyond it was a brief stretch of road shut in by hoardings and dominated by high masts of scaffolding, behind which new Government buildings were in process of erection. Across each front to left and right a few strings of bunting fluttered to give festive relief; for here there were no stands filled with spectators, no pavements lined with shouting crowds; and behind the palisades work had been knocked off for the day. The cry of the populace lulled down to a mere murmur, and the trampling of the hoofs echoed strangely as they passed under the vaulted arch and along the walled-in track with its huge baulks of timber on both sides supporting the growth of stone walls.

Ahead stood a wide gateway opening by a sharp turn into Regency Row, whose broad thoroughfare of cream-tinted façades, now bright with flags, formed an ideal rallying-ground for the sightseeing multitude.

"Now there," said the King, pointing ahead to a high triangular building facing the gates through which they were about to emerge, "there is the place that I always think a bomb might be thrown from with much certainty and effect, plump into the middle of us, just as we are turning the corner."

"I do wish you would leave off talking about such things," said the Queen reproachfully, "or wait till we are safe home again. How can I keep on smiling, if you go putting bombs into my head?"

"I was only saying, my dear——"

Suddenly, from behind, an amazing detonation seemed to strike at the smalls of their backs, throwing them half out of their seats. The glass slide upon the Queen's side of the coach ran down with a crash, and one of the large gilt baubles from its roof toppled and fell into the road. At the same instant a great blast and swirl of smoke blew by, shutting for a moment the outer world from view. Then loud cries, hullabalooings, shoutings—a scramble and clatter of hoofs as though three or four horses had gone down and were up again—a capering flash of pink silk calves—as the six footmen exploded upon from the rear sought safety in front where the eight piebald ponies were all standing on end with men hanging on to their noses. And then further disorder of a less violent kind, runnings to and fro, and from the crowd waiting ahead a vast and tumultuous cry rather jovial in its sound.

The King had risen from his seat, and trying to look out and see what was going on behind had put his head through the glass, his crown acting as a safe and effective battering ram.
